Integrating Image Coding and Indexing for Content-based Image Retrieval

We believe that image coding and image indexing have many commonalities. Integrating image coding and image indexing may prove to be a very effective way to managing the ever increasing image/video data. We have developed several technologies to achieve the integration of image coding and indexing to facilitate image retrieval, including, methods based on binary space partitioning tree, block truncation coding and 2nd generation image coding.
