Most indexing systems are based on global image descriptors. Nowadays, new representations are used. They try to describe images more precisely without exploiting any semantic description. They use local statistics and their relationships in the image. In this paper, we present these approaches and introduce a new representation system based on a pyramidal graph. First results are also presented which show that the proposed system is very promising for both partial and global requests.
