I split screen into segments for my classifier. I don't just want to classify each segment, I want the pixel coordinates of each segment as well. How do I do this?
thanks

Are the segments all the same size? If so then you should be able to easily convert segment index to screen coordinates.
coordinates_of_start = (index - 1) * width_in_this_direction + 1;
coordinates_of_end = index * width_in_this_direction;

index is the number of the segment in a particular direction. So the 3rd segment down, 4th over, would call for index numbers 3 for vertical direction and 4 for horizontal direction.

What do you mean by segmentation for your classifier? Is it like you want to segment the standard peppers.png demo image into purple region(s), red regions, green regions, and yellow regions, and you want the pixel coordinates of each segment (each class)? And you want to split up the screen to show masks for each segmentation (class)? If so, you can segment the image using whatever method you want, such as classify() function or the Color Thresholder app, then take the mask for each color class and use find() or regionprops() to get the (x,y) coordinates for each class.
