EXPLORATION OF POSSIBILITY TO INCREASE PERFORMANCE OF METHOD FOR NOISE VARIANCE EVALUATION IN DIGITAL IMAGES
The method for blind noise variance evaluation based on analysis of distributions of discrete cosine transform coefficients is considered. The possibility to improve computational efficiency of this method by means of decreasing number of processed blocks is explored. Numerical simulation results ob...
