A Denoising Method of Image Details Preserving
Yonggang He · Aeronautical Computing Technique · 2009
Total Variation noise removal method is developed extensively since presented.It modify images towards piecewise constant functions,so leading to lose a lot of details.We propose a mechanism that better preserves fine features in such denoising processes.This is accomplished by constraining fidelity item constructed by local variance.Our results show improvement in the signal-to-noise ratio over total variation method,and they are more appealing visually.
