If I write for example image=255*image, the value of image is not updated (I should get a full white image). Is this normal ? Do I have to go through inner loops to multiply each element ?
What is the datatype of your matrix? (If you want it to be white, a image.setTo(255) for an CV_8UC1-image does the job)
Have you maybe passed your image by value instead of reference?
the image come from image = imread(argv[1], CV_LOAD_IMAGE_GRAYSCALE); So it should be CV_8UC1. I don't want the image to be white, it was just for testing the multiplication. What do you mean by passing by value instead of reference ? Normally it should be automatically be passed by reference, no ?
Hi!
there is probably something wrong with your code, because this works for me... Can you post the code you use?
