Recent Projects

Large-scale image search and classification

Fast binary code based indexing schemes for large-scale image search.

Cross-modal image retrieval

A system for cross modal image retrieval learned from Flickr data. The user can use images to query image, and can also use tags to query images. Left sample images correspond to tag queries “deer” and “deer snow”.
