The function cv::split does the reverse operation. If you need to shuffle channels in some other advanced way, use cv::mixChannels.

Web29 de abr. de 2024 · I think the default format is BGR only. You can always use cv2.cvtColor (img, cv2.COLOR_BGR2RGB) after reading the image to convert the image to RGB. ` def get_image (self, filePath): return cv.imread (filePath)` code is this and return the image as RGB (when I show it up at screen it's seems like as seems on windows image viewer). hightidepoolservices.comWeb42. You may use cv2.merge () to add the alpha channel to the given RGB image, but first you need to split the RGB image to R, G and B channels, as per the documentation: Python: cv2.merge (mv [, dst]) mv – input array or vector of matrices to be merged; all the matrices in mv must have the same size and the same depth.
