Hi, I am trying to clone the results and technique of this website https://www.visualizecolor.com/voc#/PaintPhoto?projectid=5791b5a0-9567-4159-a7dd-25e54481a17a Using open cv in Python. So far i have tried converting BGR 2 HSV and then get the pixel color and make mask but it's not making same results. then i have tried segmentation. Even gray scale also,I just need help in selection of mask. any hint will be really appreciated. Attached the image for refrence purpose.
