Abstract:
1. A method for improving iterative results of Content-Based Image Retrieval (CBIR) using relevance feedback, the method comprising: obtaining a set of positive feedback images and a set of negative feedback images via relevance feedback, the set of positive feedback images are those images deemed semantically relevant and the set of negative feedback images are those deemed semantically less relevant; within a feature space, moving a positive candidate images towards the positive feedback images, the positive candidate images having similar low-level features as those of the set of positive feedback images, wherein the moving further comprises: within a feature space, distancing negative candidate images from the set of positive feedback images, the negative candidate images having similar low-level features as those of the set of negative feedback images; calculating distances based upon a Bayesian decision boundary function; sorting images based upon calculated distances, wherein the sort is performed as if no negative feedback images exist.
