A novel image retrieval algorithm based on the color anddistribution of interest points
Baolong Guo · Journal of Xidian University · 2005
A novel algorithm for image retrieval based on interest points is presented. Interest points are regarded as the vision clues, and an annular color histogram is designed, which takes not only the local color feature into consideration, but also the space distribution information of interest points. With robustness to rotation and translation, the algorithm avoids the shortcoming of losing the location information in color histogram. Experimental results show that this algorithm is simple and improves the image retrieval efficiency.
