Is it possible to use python openCV to detect and count human cell based on color?

For example, in this picture, I want to detect cell that positive blue and green separate from those blue and yellow.enter image description here

    yes, you can definitely do that, but could you share your code snippet for what issue you are facing while implementing it ? or this was just a question to know yes or no ? – warl0ck Oct 29 '18 at 08:29
  • sorry I'm newbie in openCV what I know is detection based on 1 color but i dont know how to detect object basd on 2 color. – Naravut Suvannang Oct 29 '18 at 08:49
  • If blue is the common color then simply focus on green and yellow color segmentation ? – ZdaR Oct 29 '18 at 08:51

    Here is [my result with specific color removed](https://i.stack.imgur.com/dK0dA.png) . [This link](https://stackoverflow.com/questions/47483951/how-to-define-a-threshold-value-to-detect-only-green-colour-objects-in-an-image/47483966#47483966) maybe help. – Kinght 金 Oct 29 '18 at 09:11
  • Blue is Staning for nuclear of the cell. So if green and yellow present without blue is don’t count. – Naravut Suvannang Oct 29 '18 at 13:23
