Reverse Searching with Images

A new resource added to our Images page is Tineye, a "reverse search engine" that allows you to input an image and find out "where an image came from, how it is being used, if modified versions of the image exist, or if there is a higher resolution version." Using image identification technology, Tineye finds results from a database of over a billion images and includes the URL from which they originated so that the user can track the life of the image and, in some cases, determine its origin.

It is important to note that Tineye cannot search for similar images; rather, it finds the same image in various locations and incarnations. It is thus useful for tracing one's own work (commercial accounts are available for companies who want to do this) or any image of interest, but it will not find different images that contain, for example, the same person.

To give you an idea of what Tineye can do, here are a couple of examples of search results.

Alternative Archives: Radical Software

As Noel prepares to lead a Best Practices for Digital Images workshop here at UT, the rest of us in the Visual Rhetoric group hope to make some of this work public here on viz. for others to use. One website that presents some interesting work done in the 1970s that theorizes the use and creation of digital/video media is Radical Software.

Radical Software was created, according to its website, out of the work of a group called the Raindance Foundation which hoped to be “an alternative media think tank; a source of ideas, publications, videotapes and energy providing a theoretical basis for implementing communication tools in the project of social change.” A part of this work involved publishing a magazine called Radical Software that discussed in various ways the power of technology (principally video) to transmit diverse and alternative messages. What the creators of this website have done is to scan all of the issues of Radical Software (published between 1970 and 1974) as PDFs and make them available to the public for searching and browsing.

What really struck me in looking over the website is the relevance that some of their theorizing might have for individuals working in education and digital humanities today. Their last issue on “Video and Kids” features a number of individuals reflecting on the ways in which they’ve used video in the classroom not only to teach students material but also to show children ways of producing their own work. This is something that the Internet itself has further democratized as the tools required now for digital interaction have become cheaper and the knowledge to use them is ready to hand. What also intrigued me is that Radical Software from the first viewed their work as open-source and encouraged readers to copy freely from it. This more open attitude seems to mirror the kind of work done today by publications like Kairos, which not only offer space for more creative kinds of scholarship but also lower the wall preventing the public from accessing it.

I found it fairly easy to navigate the site and browse between issues, although having each article be its own separate PDF on themakes it harder to read through an entire issue. (Luckily, they do have full issues in PDF, but they're available only by clicking on the cover of the issue and not visible under the contents section, which makes this feature harder to find.) The search itself is also easy to use, although it appears that the articles haven’t been associated with likely keywords: while a search on “education” yields 155 results, “pedagogy” finds none. If there were any improvement that could be made to this site, this would be helpful, but the website appears to be designed—like the magazine itself once was—for easy access by others. I hope anyone interested in the evolution of digital literacy and the use of technology will find this a useful resource.

MIT project documents videos removed from YouTube

CNET reports MIT has a new project that provides information about videos that have been removed from YouTube. From the article:

The site, an effort by the MIT Free Culture group, scans the most popular YouTube videos for the metadata Google inserts after a video has been taken down. YouTomb shows a list of recently removed videos (which you can’t actually view), who requested their removal, when they were taken down, and how long they were up beforehand.

This site should be a helpful resource for online video researchers, particularly those interested in copyright issues.
