Exploiting the Link Between Words and Pictures
There are billions of photographs with associated text available on the web. Some common areas where images and words are naturally linked include: web pages, captioned photographs, and video with speech or closed captioning. The central challenge that needs to be solved in order to organize these collections effectively is how to extract images in which specified objects are depicted from large pools of pictures with noisy text. This is a very difficult problem because the relationship between words associated with an image and objects depicted within the image is often complex.
My work has demonstrated that for many situations these collections can be mined successfully. I will talk about three projects that I have worked on in this area:
Automatically labeling faces in news photographs, classifying images from the web, and ranking iconic images from consumer photo collections. All papers, created datasets, and demos are available on my webpage at: http://www.cs.berkeley.edu/~millert/.

Recent Successes and Failures of Recognition Algorithms in Computer Vision
Recognition algorithms in computer vision have come a long way in the last 10 years. I will describe some of the successes and failures for recognition algorithms, concentrating on some of our work at Berkeley including:
- recognizing objects by matching shapes in images
- recognizing actions in video
- recognizing scenes
- indexing large collections of video by content
The talk will cover what might be the short-term future of recognition algorithms and applications.
