摘　　要：针对符号图像的细化,提出了一种并行细化算法的改进算法,通过对符号图像目标像素中非骨架点的逐层剥落,最终获得图像中符号的骨架,提高了算法的执行效率;同时在图像细化过程中记录了获得骨架点时当前正在剥落的层,为解决细化图像中特征点的畸变提供了可能。Aiming at the thinning of ideograph image, an algorithm to improve a parallel thinning arithmetic is put forward, the ideograph skeleton in image is acquired at last by wiping offthe No-skeleton points of aim pixels in ideograph image, level by level, the improved thinning algorithm proceeds more quickly. At the same time of image thinning, the skeleton points level where the No-skeleton points of aim pixels are being wiped off can be recorded, that may be used to deal with some distortions of the characteristic points .
