OpenCV中的独立HSV通道
问题描述：
我在opencv中有一个hsv mat文件，我想分隔通道.我发现cvSplit(hsv，h，s，v，NULL)，但是不适用于Mat文件.那么，如何只保留Mat图像文件中的第一个通道h呢? 我的结果是上面的.基本上就是我转换的图像，我可以看到脸，但是色调很奇怪.
I am having an hsv mat file in opencv and I want to separate the channels. I found cvSplit( hsv, h, s, v, NULL ), but it doesn't work with Mat files. How is it then, to keep just the first channel h of from the Mat image file?? My result is the above. Basically is the image that I convert, I can see the face but in weird tones.
使用的代码:
cvtColor(cropped_rgb, cropped_hsv, CV_BGR2HSV);
split(cropped_hsv, channels);
cropped_hsv = channels[0];
imshow("cropped_hsv", cropped_hsv);
答
您可以简单地使用 split :
Mat hsv;
vector<Mat> channels;
split(hsv, channels);
channels [0]，channels [1]，channels [2]将分别包含您的H，S，V.
channels[0], channels[1], channels[2] will contain your H, S, V respectively.
