摘要
针对模拟退火法在图像恢复过程中收敛速度慢的问题,提出了以“编码”方式更新像元,邻点灰度级跃迁等技术,在保证高质量图像恢复的基础上,大大加快了模拟退火法的收敛速度。
Aims at an improvement on the slow convergence speed of the Simulated Annealing (SA) algorithm when used in image restoration. Provides several improved techniques: renew all of pieces in a“codedmodel”,transition of nearby pieces, and the lik.On the basis of insuring high quality of image restoration, such techniques will speed up the speed of convergence of a simulated annealing algorithm.
