This paper proposes a novel approach for image spatial feature extraction.It uses CCVAE algorithm based on color vector angle and Euclid distance to detect original image color edge.For the edge pixels,the Edge Histogram Descriptor(EHD) is built.For the non-edge pixels,the Spatial Chromatic Histogram(SCH) is built.Experimental results show that the approach has high precision rate and recall rate.
