If I have an image (IplImage 8-bit) and a binary mask (which is also an 8-bit IplImage of the same size, where every pixel has a value of either 0 or 255), how can I make every pixel in the image that corresponds with a pixel in the mask with a value of zero have a value of zero, and every pixel in the image that corresponds with a pixel in the mask with any other value (namely 255) have the same value as in the original image?
In other words, anything that is “in the mask area” will keep its original value, and anything outside the mask area will become zero.
You can simply use
bitwise_and()function.Check the documentation.
