Image Retrieval Algorithm Based on Color Texture Shape and Relevance Feedback
基于ROI多特征和相关反馈的图像检索算法

An image retrieval algorithm by combining multiple features and relevance feedback based on ROI is pro- posed in this paper.This algorithm firstly decomposes the images by quad-tree,and then the color,texture and shape features based on ROI selected by the user are extracted for multilevel retrieval.Furthermore,the technique of rele- vance feedback,which manifests the user's semantic subjectivity is used in the algorithm to improve the performance of retrieval by adjusting the ROI-weight,the intra-weight an...
