The method for image retrieval based on multi-factors correlation utilizing block truncation coding
Multi-factors correlation (MFC) is used to describe the image. We utilize the block truncation coding to convert the color image to bitmap. Structure elements are used to represent the bitmap. Gradient value correlation is used to denote the gradient relation. Gradient direction correlation is used to denote the gradient relation.
