In order to solve it,this paper brings forward cognitive entropy concept and information compensation concept,makes thinks of compensative information of the attribute as illuminative information,and designs a kind of CID3 algorithm based on compensative information.

In order to improve the visual property and robust virtue of digital watermarking technology, the article brings forward a new algorithm for embedding and detecting digital watermarking ,which based on information fusion and information compensation.

This article,starting from the reality of verbal communication,conjoining with information transfer theory and the cognitive adding and selecting principle of the subject in communication and its process,reiterates these two terms and believes that information compensation and communicative feed are the essence of "Insertion" and "complement" but not the dynamic change,which is only the sur.

On the basis of the information compensation theory of the induction logging and the analysis of investigation characteristics of HIL, the method of resolution matching and processing technology have been obtained.

Considering the character that wavelets decomposition naturally lows dimension and the character that multiresolution analysis spaces are orthogonal complement,this paper has proposed a new recognition algorithm by constructing information compensation tree,which can adaptively extract unequal quantity feature information from each class and ha.
