Description: 在VS2005下编写的vfw的程序，通过vfw方式打开摄像头，并得到原始数据进行处理。其中摄像头必须支持RGB24格式的数据输出。代码中有RGB24转灰度、迭代阈值化等算法。-Prepared under the vfw in VS2005 program, open the camera through vfw, and the raw data for processing. One camera must support RGB24 format of data output. Code in RGB24 turn gray, iterative thresholding algorithm. Platform: |
