It is necessary to find the points on the surgeon's gloves. Example of the photo below.

I can accurately define the contour of the hand using an hsv filter. Now the algorithm works well with the help of Template Matching. But still not good enough for my purposes.

There may be some ideas about how to improve the program (without adding new templates). I tried many variants of the trehsholding, but came to a standstill because there are a lot of noise.

Tetragramm

7376 ●13 ●37

Try the niBlackThreshold

ximgproc::niBlackThreshold( im, thresh, 255, THRESH_BINARY_INV, 21, -1.0 );

That gives me images something like this:

Not perfect, but you said you have hand contours, so you can drop everything outside of that, then filter the inner blobs by shape and intensity. The false alarms will still be white. Or do template matching on each one to see how closely it matches, and only keep the good ones. Lots of ways to remove false alarms, if you get good, distinct, blobs.
