Hi,  
well, pretty easy issue, but IDK if it is already solved or… Dont know where is it solved.

I have an image, with a big shape well detected with findContours in the middle of the screen (OK) but in one of the corners there are 2 tiny detected bodies that I coudnt discard with any kind of morfology and I would like to discard with this findContours function.  
There is any function that might help me to discard the tiny bodies? thank you!

look up `contourArea`, discard contours that are small by that measure.

here’s an example: [OpenCV: Image Moments](https://docs.opencv.org/master/d0/d49/tutorial_moments.html)
