Furthermore, it is shown that for each belief set operator satisfying strong belief cumulativity there exists a largest monotonic logic underlying it, thus generalizing a result for nonmonotonic inference operations.

In this paper, the basic problem in geometric modelling, the regularized set operation of regularized geometric objects, is discussed. The paper first presents a definition of the regularized geometric objects by analysing the boundary of geometric objects based on the concept of connection. Then it shows a hierarchic boundary representation scheme and a formal description of regularized set operator. Finally, the steps to implement the regularized set operator are presented.

In order to eliminate impulse noise and preserve the fine structure features of the image, a method of the image denoising based on monotony set operator is presented. This method, firstly, uses the threshold decomposition principle to decompose the image into a bank of level sets, and then apply a special set operator to filter the level sets, finally restructure a image with the level sets filtered. To compare with traditional medial filter and Gaussian filter, the image denoising method based on set operator has the characteristics of shape preserving and contrast invariant. In addition, Fast algorithm based on Heap data structure is presented in order to increase the efficient of the filter algorithm. According to connection, the algorithm can find maximum and minimum regions, and if the area of the regions is less than a special value, then they will be cut. So the small peaks and small vales in the image can be eliminated. Experimental results show that the efficient of the algorithm is obvious over the method used one by one threshold, and set operator has remarkable advantages in terms of eliminating impulse noise, shape preserving and contrast invariant.
