Application Research of Homogeneous Texture Descriptor in Content-Based Image Retrieval

The homogeneous texture descriptor is one of MPEG-7 texture descriptors. This descriptor describes the texture information of an image or the region of interest in an image. A new texture feature wedge feature is proposed, which emphasizes the texture direction. The homogeneous texture descriptor owning the new feature is more suitable to content-based image retrieval system. The experimental results show this method can get better retrieval recall and accuracy ratio comparing with that of only using the texture energy or the generalized gray co-occurrence matrix.
