图形图像处理，基于灰度直方图单阈值分割算法的研究-Graphic image processing, histogram-based threshold segmentation algorithm based on a single research

delphi实现实时获得摄像头数据并且肤色模型阈值过滤，以及形态学膨胀处理。因为delphi这方面资料特别少，特地做了一个贡献给大家。-delphi real-time access to data and color model of the camera threshold filtering, and morphological expansion processing. Delphi this information because of the special little speci

调整对比度：首先设定一个阀值，通常是128；然后判断像素点的R，G，B值，凡是大于128的， 增加一个值，小于128的，减少一个值-Adjust the contrast: First, set a threshold, usually 128 then determine the pixel R, G, B values, all greater than 128, add a value smaller than 128, reduce the value
