Question

I want to apply a binary mask to a color image.
Please provide a basic code example with proper explanation of how the code works.

Also, is there some option to apply a mask permanently so all functions operate only within the mask?

Answer 1

You don’t apply a binary mask to an image. You (optionally) use a binary mask in a processing function call to tell the function which pixels of the image you want to process. If I’m completely misinterpreting your question, you should add more detail to clarify.
