Application of PatchNet in image representation

PatchNet, as a graph model with hierarchical structure, is a new technology of image representation. Its description structure for images can well conform to the cognitive features of human visual system. The semantic information and geometric structural information can be stored and represented compactly. PatchNet can realise abstract representation of an input image. This paper introduces the PatchNet representation of images, describes the detailed structure of PatchNet, and analyses how to apply PatchNet in content searching and editing based on image library.
