Image Recognition: Think Tattoo Recognition

June 8, 2016

I know that some bad guys encourage their “assistants” to get facial tattoos. I am not personally into tattoos, but there are some who believe that one’s immune system is strengthened via the process. The prison tattoos I have seen in pictures mind you, did not remind me of the clean room conditions in some semi conductor fabrication facilities. I am confident that ball point pen ink, improvised devices, and frequent hand washing are best practices.

I read “Tattoo Recognition Research Threatens Free Speech and Privacy.” The write up states:

government scientists are working with the FBI to develop tattoo recognition technology that police can use to learn as much as possible about people through their tattoos.

The write up points out that privacy is an issue.

My question:

If a person gets a facial tattoo, perhaps that individual wants others to notice it?

I have heard that some bad guys want their “assistants” to get facial tattoos. With a message about a specific group, it makes it difficult for an “assistant” to join another merry band of pranksters.

Turn to Unsplash for Uncommon Free Photos

June 7, 2016

Stock photos can be so, well, stock. However, Killer Startups points to a solution in, “Today’s Killer Startup: Unsplash.” Reviewer Emma McGowan already enjoyed the site for its beautiful free photos, with new ones posted every day. She especially loves that their pictures do not resemble your typical stock photos. The site’s latest updates make it even more useful. She writes:

“The new version has expanded to include lovely, searchable collections. The themes range from conceptual (‘Pure Color’) to very specific (‘Coffee Shops’). All of the photos are free to use on whatever project you want. I can personally guarantee that all of your work will look so much better than if you went with the usual crappy free options.

“Now if you want to scroll through beautiful images a la old-school Unsplash, you can totally still do that too. The main page is still populated with a seemingly never ending roll of photos, and there’s also a ‘new’ tab where you can check out the latest and greatest additions to the collection. However, I really can’t get enough of the Collections, both as a way to browse beautiful artwork and to more easily locate images for blog posts.”

So, if you have a need for free images, avoid the problems found in your average stock photography, which can range from simple insipidness to reinforcing stereotypes and misconceptions. Go for something different at Unsplash. Based in Montreal, the site launched in 2013. As of this writing, they happen to be hiring (and will consider remote workers).

No Search Just Browse Images on FindA.Photo

March 2, 2016

The search engine FindA.Photo proves itself to be a useful resource for browsing images based on any number of markers. The site offers a general search by terms, or the option of browsing images by color, collection (for example, “wild animals,” or “reflections”) or source.  The developer of the site, David Barker, described his goals for the services on Product Hunt,

“I wanted to make a search for all of the CC0 image sites that are available. I know there are already a few search sites out there, but I specifically wanted to create one that was: simple and fast (and I’m working on making it faster), powerful (you can add options to your search for things like predominant colors and image size with just text), and something that could have contributions from anyone (via GitHub pull requests).”

My first click on a swatch of royal blue delivered 651 images of oceans, skies, panoramas of oceans and skies, jellyfish ballooning underwater, seagulls soaring etc. That may be my own fault for choosing such a clichéd color, but you get the idea. I had better (more various) results through the collections search, which includes “action,” “long-exposure,” “technology,” “light rays,” and “landmarks,” the last of which I immediately clicked for a collage of photos of the Eiffel Tower, Louvre, Big Ben, and the Great Wall of China.

She Is a Meme Librarian

January 20, 2016

Memes are random bits of Internet culture that come and go faster than the highest DSL speed.  There are so many memes out there that it seems impossible to catalog the trends, much less each one.  The Independent tells us that Amanda Brennan has made a career out of studying and documenting memes, becoming the world’s first meme librarian: “Meet Tumblr’s ‘Meme Librarian,’ The Woman With The Best Job On The Internet.”

Brennan works at Tumblr and her official title is content and community manager, but she prefers the title “meme librarian.” She earned a Master’s in Information from Rutgers and during graduate school she documented memes for Know Your Meme, followed by Tumblr.

“[In graduate school] immediately I knew I did not want to work in a traditional library. Which is weird because people go to library school and they’re like ‘I want to change the world with books!’ And I was like ‘I want to change the world of information.’ And they started a social media specialization in the library school, and I was like, ‘This is it. This is the right time for me to be here.’”

Brennan is like many librarians, obsessed with taxonomy and connections between information.  The Internet gave her an outlet to explore and study to her heart’s content, but she was particularly drawn to memes, their origins, and how they traveled around the Internet.  After sending an email to Know Your Meme about an internship, her career as a meme librarian was sealed.  She tracks meme trends and discovers how they evolve not only in social media, but how the rest of the Internet swallows them up.

I wonder if this will be a future focus of library science in the future?

Bing Uses Image Search for Recipes

December 8, 2015

Recipe websites have become the modern alternative to traditional cookbooks, but finding the perfect recipe through an Internet search engine can be tedious. LifeHacker informs us that Bing is now using image search technology to help users whittle down the results in, “Find Recipes by Image in Bing’s Image Search.” Writer Melanie Pinola describes how it works:

“When you look up ‘baked ziti’ or ‘roast turkey’ or any other food-related term and then go to Bing’s images tab, photos that you can access recipes for will have a chef’s hat icon, along with a count of how many sites use that image. Click on the image to see the recipe(s) related to the image and load them in your browser. You’ll save some time versus click through to every recipe in a long list of search results, especially if you’re thinking of making something that looks a particular way, such as bacon egg cups.”

So remember to use Bing next time you’re hunting for a recipe online. Image search tech continues to improve, and there are many potential worthwhile uses. We wonder what it will be applied to next.

Algorithmic Bias and the Unintentional Discrimination in the Results

October 21, 2015

The article titled When Big Data Becomes Bad Data on Tech In America discusses the legal ramifications of relying on algorithms for companies. The “disparate impact” theory has been used in the courtroom for some time to ensure that discriminatory policies be struck down whether they were created with the intention to discriminate or not. Algorithmic bias occurs all the time, and according to the spirit of the law, it discriminates although unintentionally. The article states,

“It’s troubling enough when Flickr’s auto-tagging of online photos label pictures of black men as “animal” or “ape,” or when researchers determine that Google search results for black-sounding names are more likely to be accompanied by ads about criminal activity than search results for white-sounding names. But what about when big data is used to determine a person’s credit score, ability to get hired, or even the length of a prison sentence?”

The article also reminds us that data can often be a reflection of “historical or institutional discrimination.” The only thing that matters is whether the results are biased. This is where the question of human bias becomes irrelevant. There are legal scholars and researchers arguing on behalf of ethical machine learning design that roots out algorithmic bias. Stronger regulations and better oversight of the algorithms themselves might be the only way to prevent time in court.

Plethora of Image Information

July 24, 2015

Humans are visual creatures and they learn and absorb information better when pictures accompany it.  In recent years, the graphic novel medium has gained popularity amongst all demographics.  The amount of information a picture can communicate is astounding, but unless it is looked for it can be hard to find.   It also cannot be searched by a search engine…or can it?  Synaptica is in the process of developing the “OASIS Deep Image Indexing Using Linked Data,”

OASIS is an acronym for Open Annotation Semantic Imaging System, an application that unlocks image content by giving users the ability to examine an image closer than before and highlighting data points.  OASIS is linked data application that enables parts of the image to be identified as linked data URIS, which can then be semantically indexed to controlled vocabulary lists.  It builds an interactive map of an image with its features and conceptual ideas.

“With OASIS you will be able to pan-and-zoom effortlessly through high definition images and see points of interest highlight dynamically in response to your interaction. Points of interest will be presented along with contextual links to associated images, concepts, documents and external Linked Data resources. Faceted discovery tools allow users to search and browse annotations and concepts and click through to view related images or specific features within an image. OASIS enhances the ability to communicate information with impactful visual + audio + textual complements.”

OASIS is advertised as a discovery and interactive tool that gives users the chance to fully engage with an image.  It can be applied to any field or industry, which might mean the difference between success and failure.  People want to fully immerse themselves in their data or images these days.  Being able to do so on a much richer scale is the future.

Google and Disappeared Streets

July 14, 2015

If you spend any time with Google Maps (civilian edition), you will find blurred areas, gaps, and weird distortions which cause me to ask, “Where did that building go?”

If you really spend a lot of time with Google Maps, you will be able to see my two dogs, Max and Tess, in a street view scene.

And zoomed in. Aren’t the doggies wonderful?

The article “The Curious Case of Google Street View’s Missing Streets” is not interested in seeing what the wonky Google autos capture. The write up pokes at me with this line:

Many towns and cities are littered with small gaps in the Street View imagery.

The write up explains that Google recognizes that gaps are a known issue. The article gets close to something quite interesting when it states:

In extreme cases, whole countries are affected. Privacy has been a particular issue in Germany, where many people objected to the roll-out of Street View. Google now has Street View images only for big cities in Germany, like Berlin and Frankfurt, and appears to have given up on the rest of the country completely. Zoom out over Europe in Street View mode and Germany is mostly a blank island in a sea of blue.

Want to do something fun the author of the write up did not bother to do? Locate a list of military facilities in the UK. Then try to locate those on a Google Map. Next try to locate those on a Bing.com map (oops, Uber map)?

Notice anything unusual? Now relate your thoughts to the article’s list of causes.

If not, enjoy the snap of Max and Tess.

Why Are Ads Hiding Themselves

June 25, 2015

The main point of an advertisement is to get your attention and persuade you to buy a good or service.  So why would ads be hiding themselves in a public venue?  Gizmodo reports that in Russia certain ads are hiding from law enforcement in the article: “This Ad For Banned Food In Russia Itself From The Cops.”  Russian authorities have banned imported food from the United States and European Union.   Don Giulio Salumeria is a Russian food store that makes its income by selling imported Italian food, but in light of the recent ban the store has had to come up with some creative advertising:

“Websites are already able to serve up ads customized for whoever happens to be viewing a page. Now an ad agency in Russia is taking that idea one step further with an outdoor billboard that’s able to automatically hide when it spots the police coming.”

Using a camera equipped with facial recognition software programmed to recognized symbols and logos on officers’ uniforms, the billboard switches ads from Don Giulio Salumeria to another ad advertising a doll store.  While the ad does change when it “sees “ the police coming, they still have enough time to see it.  The article argues that the billboard’s idea is more interesting than anything.  It then points out how advertising will become more personally targeted in the future, such as a billboard recognizing a sports logo and advertising an event related to your favorite team or being able to recognize your car on a weekly commute, then recommending a vacation.   While Web sites are already able to do this by tracking cookies on your browser, it is another thing to being tracked in the real world by targeted ads.

MIT Discover Object Recognition

June 23, 2015

MIT did not discover object recognition, but researchers did teach a deep-learning system designed to recognize and classify scenes can also be used to recognize individual objects.  Kurzweil describes the exciting development in the article, “MIT Deep-Learning System Autonomously Learns To Identify Objects.”  The MIT researchers realized that deep-learning could be used for object identification, when they were training a machine to identify scenes.  They complied a library of seven million entries categorized by scenes, when they learned that object recognition and scene-recognition had the possibility of working in tandem.

“ ‘Deep learning works very well, but it’s very hard to understand why it works — what is the internal representation that the network is building,’ says Antonio Torralba, an associate professor of computer science and engineering at MIT and a senior author on the new paper.”

When the deep-learning network was processing scenes, it was fifty percent accurate compared to a human’s eighty percent accuracy.  While the network was busy identifying scenes, at the same time it was learning how to recognize objects as well.  The researchers are still trying to work out the kinks in the deep-learning process and have decided to start over.  They are retraining their networks on the same data sets, but taking a new approach to see how scene and object recognition tie in together or if they go in different directions.

Deep-leaning networks have major ramifications, including the improvement for many industries.  However, will deep-learning be applied to basic search?  Image search still does not work well when you search by an actual image.
