If you are a beginer in opencv and you know python I think that when you read this page you choose page Opencv-Python tutorials. But How do you guess that you can find python tutorials in opencv tutorials pages too ? example : https://docs.opencv.org/trunk/d3/d96/tutorial_basic_geometric_drawing.html https://docs.opencv.org/trunk/dc/dd3/tutorial_gausian_median_blur_bilateral_filter.html
full list for imgproc is on this page
Have you got an idea to add a note in openv page ?
I think a link is missing for java too
