Restoration algorithm to line similar pixels in noisy image through detection, wash out, competition and tight frame smoothing filtering

A new directional operator structure in uniform standard format is presented. From reference to manmade Game, through detection, wash out, competition and tight frame smoothing filtering, a non orthogonal, non perfect reconstruction and non recursive analysis and synthesis filtering macro plan and micro algorithm are proposed. With simplified and optimized strategy of coarsely detecting lines then delicately searching zigzags, and under game rules of minority obey majority and weaker follow stronger, the task of restoring line similar pixels from noisy image is completed successfully. Varity of experiments are made to check the effectiveness, consistency and reliability of proposed algorithm, and some well results are obtained. At final, some faithful objective evaluate on experimental results of new method is made, and the limitation and shortcoming of it is pointed out.
