Image filter method based on maximal entropy principle

摘要

This paper selects Haar wavelet as the basis, using the soft threshold method wavelet coefficients of compression processing, image filtering experiment is accomplished by wavelet compression de-noising method. The approach to determine the appropriate threshold coefficient affects the noise level directly, so the approach used to determine the threshold coefficient is very important. The maximum entropy principle is used to determine threshold coefficient in this paper. De-noising experimental results of a picture with noise shows that the method to determine the threshold coefficient through the maximum entropy principle and then wavelet compress de-noising is accomplished, which is used to complain combine the threshold coefficient through the maximum entropy principle and wavelet compression de-noising and the result is satisfied.
