Web1 answer. The output of convertTo will have the same channels count as input. It seem like CurrentMat has CV_32FC4 type, so Result will have CV_8UC4 ( CV_8UC4 == 24 ). If you want to convert your image from 4-channel to 3-channel you should use cvtColor with CV_BGRA2BGR (or CV_BGRA2GRAY for single channel output): Thanks that worked. WebIn this case, you also need to specify the type of each matrix element- CV_8U here, which corresponds to 1-byte pixel (grayscale) images. The U letter here means it is unsigned. You can also declare signed numbers using S. For a color image, you would specify three channels ( CV_8UC3 ). WebMar 11, 2014 · 기본적으로는 아래와 같다.
