Analysis of Several Structure Models of Image

Yu Wei-yu Yu Ying-lin Pan Xiao-zhou Xie Sheng-li(Institute of Electronic Engineering and Control, South China Univ. of Tech., Gu angzhou 510640, Guangdong, China)  
By employing the evolution model of one-dimension signals, an evolution model o f the image is constructed in a generalized space, and the relationships between the parameters of the proposed model and the physical variables of the image ar e given, on the basis of which a structural information model of the image is pr oposed, H (Tran) being defined as the structure entropy of the image. It is indicated that images should evolve to achieve the highest structure entropy . Moreover, a hierarchical structure model is established, all terminal nodes of which form a semantic string. The semantic code of the image is finally defined . The information quantity and entropy of this code are respectively considered as the semantic information and the semantic entropy.
