In this paper we propose a subblock-based compact color descriptor and present a hardware design for this descriptor, which contains four main sections: partition, quantification, histogram computation, and Haar transform. It can be used for video content filtering, image matching, sketch-based matching and browsing application. Several design solutions of the descriptor extraction are given
