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 ?
Hi!
there is probably something wrong with your code, because this works for me... Can you post the code you use?
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 ?
