Image Retrieval

Query by Example: finding more images in a
collection that are like the target.

Image retrieval comprises any technology designed to locate particular images within large collections, such as those found on the world wide web. Although many techniques exist, including some that look at the text and labels surrounding an image, I am most interested in content-based image retrieval, which seeks to retrieve relevant images based on an automatic analysis of their contents.

The heart of a content-based image retrieval algorithm is its formula for measuring the similarity between any pair of images. I have developed a technique that compares images based upon a combination of the color, texture, and arrangement of entities within the image frame.
