| Abstract: | Image de-noising is a basic problem in the field of image processing,and an important content in image enhancement.The wavelet de-noising is an internationally recognized focus in the field of image de-noising research.This paper research on the application of theory of wavelet transform adopted in de-noising,traditional objective indicators of evaluation are utilized to measure the effect of various wavelet transforms.Meanwhile,the theory of structure similarity is introduced into the assessment system,and simulation results show that the metric is consistent with the subjective judgments. |
