2014-03-14 21:31:34 -0600 | asked a question | Subtraction manually Hi Folks, I'm trying to implement a function which is subtracting 2 images. (the same does subtract() of opencv)...but since OpenCv often needs 8bit-single Channel images I have to normalize my images before subtracting because the images are CV_16UC1. As I want to save time I want to have the images subtracted before normalizing. so i did it this way: (back-front=mask) it runs, but: not with the same result. When I try: the value of back is displayed. but when I move in front of the camera, the back-value changes to the front value. And the back-image is a still image which is never changed after initialization. I don't have any ideas what I've done wrong, but you?. Thx for Your help! |

My Problem: I subtract 2 Mat (each CV_16UC1 normalized to CV8_UC1) with the following code: now i want to access the values with: but every datatype I try brings a letter, a funny box but not the value...(the picture output with imshow is correct...) (I tried uchar, unsigned character, unsigned short, ushort...nothing works) Any suggestions for me? Thx in advance! |
