Hi everyone, I am working on an app using OpenCV249 on android and would like to perform thresholding on a specific area of an image. This specific area is specified by the user by doodling a yellow rectangle on the image. Once he/she has selected this area, thresholding will be performed on that yellow rectangle window only and then output the entire image on a new ImageView.
I've went through the bulk of the docs and I can't seem to find any suitable methods that allows me to define that thresholding window unfortunately. Anyone any advise please?
