Hamming embedding and weak geometric consistency for large scale image search H Jegou, M Douze, C Schmid European conference on computer vision, CBIR is desirable because most web based image search engines rely purely on metadata and this produces a lot of garbage in the results.

The relevance feedback mechanism makes it possible for CBIR systems to learn human concepts since users provide some positive and negative image labeling information, which helps systems to dynamically adapt the relevance of images to be retrieved.

This threshold neighborhood pixel values are multiplied by binomial values of the corresponding pixels.
