Matlab: How to find the right-most point of a white line within the imrect?
- by mchlfchr
i've got a question regarding the imrect() function, which is part of the image processing toolbox in MatLab.
I'd like to find a starting point within an image.
I use the imrect function for setting a region to limit and specify the lookup area,
but I can't get the point where the ROI mask is getting back mapped to the original size of the image.
As you can see on the image there is a specified rectangle (cyan-colored), which I want to inspect for the white line, especially the nearest point to the right edge of the rectangle. I experimentated with only looking up on the last column of the rectangle, but as I mentioned before, the re-mapping onto the global image coordinates failed.
So in this example, the white point I'd like to get would be around (98,302)
The original (x,y) coordinates are relevant, so a cropping of the image to the rectangle is not acceptable.
So, do you have any ideas?
Thanks for any helping comments.
Kind regards,
