Finding Images

A better way to search online.

Searching for images on the Internet can be hit or miss. That’s because most image searches rely on metadata (text associated with the images, such as file names or dates), and metadata can be incomplete–if it’s there at all. Software that analyzes the images themselves has been notoriously unreliable. But it could get a boost from a technology developed at the University of California, San Diego.

The technology is based on existing systems that learn to describe pictured objects in terms of features like color, texture, and lines by practicing on pictures in a database of known objects. The UCSD system adds a new twist: it assigns each image a likelihood of belonging to categories such as “sky,” “mountain,” or “people.” Then it uses those words to label parts of the pictures. The technique is 40 percent more accurate than typical content-based image-search methods, says Nuno ­Vasconcelos, a UCSD professor.
