Hi,I am trying to do histogram equalization using opencv java, but i keep getting Assertion failed (_src.type() == CV_8UC1) anyone can help?

this is my code Mat doraImage= Imgcodecs.imread("C:/test/dora.jpg" , Imgcodecs.CV_LOAD_IMAGE_COLOR);

if(doraImage.channels() == 3) { doraImage.convertTo(doraImage, Imgproc.COLOR_BGR2YCrCb); else if(doraImage.channels() == 4) { doraImage.convertTo(doraImage, Imgproc.COLOR_BGR2YCrCb); } Imgproc.equalizeHist(doraImage, doraImage);
