Abstract

The problem whether the threshold value is reasonable is very important to the binary or multi mask image formed under the condition of multi-interference information, and it is really the key to delete the interference information and extract the useful information. In this paper, the author discussed the problem as to whether the method is reasonable or not in judging the threshold value under the condition of forming binary mask image with single interference factor based on different thresholds and deleting interference information based on multi-value masking image with reasonable threshold, with the purpose of extracting the alteration information. The results show that, if the same non- interfering regions can be extracted based on the binary or multi mask image with multi-interference information, the threshold value is reasonable in forming binary mask image with single interference factor, the multi-interference information will underlap each other, the interference information or the false information can be deleted and the true alteration information can be extracted based on the true multi mask image.
