python-3.x - Digital image processing of corn kernels

Question

insect infested (with hole and fading yellow color) and good corn kernelsI am trying to identify and count insect-infested corn kernels from good or healthy corn kernels. I have done the thresholding up until drawing contours around all the corn kernels in the image. FYI, the insect-infested kernels have holes and fading yellow color. How should I get the percentage of infested kernels from an image with the infested and good kernels? I am also open to other suggestions.
