程序实现一个自适应阈值的算法，用以在不规则光照下从背景中提取出前景图像。-Procedures to achieve an adaptive threshold algorithm to extract the foreground from the background image in the irregular light.

依据传统的OTSU算法，对它进行改进后的自适应阈值分割算法-OTSU algorithm based on the traditional, to improve it after the adaptive thresholding algorithm

In this paper, an automatic oral liquid light inspection algorithm is designed to implement the detection of particles in oral liquid. Second-difference and accumulate difference methods are used to remove the background information the sequence
