In this model, thesubsystem_slwrap_toGrayScalesubsystem resides in theRGBtoGRAY_Liblibrary. You create thesubsystem_slwrap_toGrayScalesubsystem by using theOpenCV Importer. The subsystem accepts an RGB image from the Image From File block and converts it to a grayscale output image. The output...
{//here you can use cv::IMREAD_GRAYSCALE to load grayscale image, see image2cv::Mat3bconstimage1 = cv::imread("C:\\workspace\\horse.png", cv::IMREAD_COLOR); cv::Mat1b image1_gray; cv::cvtColor(image1, image1_gray, cv::COLOR_BGR2GRAY); cv::imshow("image1", image1_gray)...

请注意,如果您使用的是较旧的OpenCV版本(例如OpenCV 2.x),您可能需要升级到OpenCV 3.x或更高版本,以便使用cv2.IMREAD_GRAYSCALE。 结论 "module 'cv2' has no attribute 'CV_LOAD_IMAGE_GRAYSCALE'"错误的解决方案是将代码中的cv2.CV_LOAD_IMAGE_GRAYSCALE替换为cv2.IMREAD_GRAYSCALE。通过使用正确的常量来加...
最近写代码,使用到了CV_LOAD_IMAGE_GRAYSCALE,其为将原图转为灰度图片。如: Mat srcImage = imread("srcImage.png", CV_LOAD_IMAGE_GRAYSCALE); 其转为灰度的计算公式为: Gray = 0.299 * R + 0.587 * G + 0.114 * B 但在Opencv4中,CV_LOAD_IMAGE_GRAYSCALE却找不到,经过查看Opencv的API可知,CV_...
After that, you can get your blue channel image. Normally, the blue channel of an colour image in opencv is the first layer (cuz they put 3 channels as BGR). By the way, if you wanna use the copy each pixel method, you can initial an empty image Mat result_blue(src.rows, src....
