Counting eggs of hen

edit

You can count egg blobs doing simple color threshold (choose color space model ) For overlapping eggs you can use watershed algorithm with Distance transform like in this example but instead of doing simple threshold

threshold(bw, bw, 40, 255, CV_THRESH_BINARY | CV_THRESH_OTSU);

Use InRange function.

please provide some additional images if you have. let's think on a more general solution.

@Ziri.. Just, I have one doubt. If the color of the holder and eggs are same

Hi Ziri, Thanks a lot for your kind help.. I added 2 more pictures.. and , I want to count white and brown eggs

You can start by preparing training data ( positive and negative images) of egg with different colors in different situations... then use cascade classifier Check this link . -If results are not satisfying you'll have to use better methods ( Convolutional Neural Network ).

Hi Ziri, Thanks again.. I'll test cascade classifier first and try CNN if needed..

i think cascade classifier dont work. try new train_HOG.cpp there is a PR waiting to be accepted.

As worse as a cascade classifier will fail at this (to simply object and not rotation invariant) it will fail with HOG also. Your task needs something more versatile like DPM, DeepLearning, ACF/ICF ... although those are not available through OpenCV.

@nanuyo you keep updating the question, with little to no response. Can you at least respond to peoples suggestions?

sorry to Steven, as you advised, I reallised that it is not easy to count eggs on the basket with legacy computer vision algorithms. so, I will try to count eggs on the case only and removed a picture(eggs in the basket).and I want to add more simpler pictures for you .. but this editor (add comment) doesn't provide us attaching pictures.. Can I add the other pictures into the main story ?
