2020-10-18 13:25:08 -0600 | marked best answer | Detect all black pixels inside a surrounded closed white area How can i detect black pixels surrounded by closed white pixels? Background outside shapes should not be considered. See next two images: First image i would like to extract all black pixels inside the hallow shape because it's traped/surrounded by white, but image 2 have a opeing and in that case i don't need the pixels. Image 3 shows the desired capture area in red
Image 3: Desired capture area from image1 in red. Same pass on image 2 should return 0 pixels (No area detected) Another example: Input: Needed area in red: EDIT 1: Code on different inputs: Image 4: OK Image 5: OK Image 6: Not OK! How to discard image6 cases? EDIT 2: The solution: |
