摘要
JLBNM图像恢复算法能得到较高的图像恢复质量(PSNR),但其中跳跃步长和环顾步长的确定是影响算法好坏的关键因素。文中给出了图像有无细节的定性化描述,先对图像本身的信息进行处理,然后根据图像内容的相关性来确定步长,在算法操作上更简单了。分析了串行的JLBNM算法的可并行化问题,并讨论了基于SMP的JLBNM并行化过程中的数据划分问题和处理器之间的通信问题,最后给出了相应的并行JLBNM算法和实验结果。
JLBNM algorithm can achieve high quality image restoration, but the jump steps and the loop steps have great relation to the image types. In this Paler. some descriptions are given for different images. First do processing for the image, then fix the steps according to the image contents, analyse the possibility Of the parallelized JLBNM based on the SMP for the first time, and discuss the data partition and the communieation between processors in the parallel processing. At last give the parallel JLBNM algorithm.
