| 摘 要： | 采用一维信号的进化模型，建立图像广义空间的进化模型，得出了各种参数与图象物理参量的关系，据此建立了图像结构信息模型，指出H(Tran)是图像结构熵，图像应向结构熵最大的方向进化．同时，建立了层次结构模型，指出各个终节点构成语义字符串，并定义了图像语义码，这个码所含的信息量及熵称为语义信息及语义熵．

| Abstract: | 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. |
