A New Approach for Image Retrieval Based on Color and Shape of Block
一种新的基于分块颜色和形状的图像检索方法

The approach for image retrieval based on single feature only can represent partial attributes of images,so its application is limited. After analyzing color feature and shape feature in images and combining their characteristics, this paper proposes a new approach for image retrieval based on color and shape of blocks. Firstly, this approach abstracts color information and character-points in the blocks of image ; Secondly, according to character-points of each block.it abstracts shape information. Finally, integrating color and shape information, it employs proper matching algorithm to implement image retrieval. The results of the experiments show that this approach not only is more accurate but also can be applied to object-based or region-based image query.
