你可以从这里下载所有的源代码或从OpenCV的事例文件夹的代码部分查阅cpp tutorial code。 最后的参数是可选择的。如果这个参数被传入,则图像会以灰度的格式来传入,否则就会用RGB的格式。第一件事情是计算查阅表(look up table)。 intdivideWith=0; stringstream s; s<< argv[2]; s>>divideWith;if(!s||!divi...
访问像素的几种方法 SimplyAccess使用at成员函数来进行像素访问,简单但是不好用,因为速度很慢! IteratorAccess适合像素便利,但速度也很慢! FastestPointAccess才是真正实用的像素访问方法,尤其是当continuous时把行设置为1,列设置为rows*cols的算法,这样非常高效且好用,应该只使用这一种像素访问方式。 void SimplyAccess...
