I found this old post where the author used mean shift filtering to isolate vegetables from background in an aerial image. Anyone knows if it is really possible ? I tried on my side using:
Imgproc.pyrMeanShiftFiltering(temp, output_image, 10.0, 50.0,1,new TermCriteria(TermCriteria.MAX_ITER|TermCriteria.EPS, 120, 0.001));
but I am not able to find correct values to obtain the same result.
