Design of an adaptive human visual filter

The design method of a kind of adaptive filters with human visual sensitivity is proposed. By analyzing on the character of human visual, we take three features of human visual sensitivity to be considered. It is shown that the algorithm is adaptive. The most of the common filters, such as mean filter, are improved into adaptive filters. It constructs simply the coefficient matrices of filters on line and combines with common filters to attain the adaptive filters in the time domain. It decreases the contradiction between reducing the noise in images and preserving the significant features. The coefficient for visual sensitivity is obtained before filtering, so it can be integrated with some other common filters to get new filters with human visual sensitivity
