System information (version)

• OpenCV => 4.4.0-pre

Detailed description

The "Structural Analysis and Shape Descriptors" page says "see below for available statistics". I looked through the page a couple of times but couldn't find information on the available statistics.

Steps to reproduce

1. Go to https://docs.opencv.org/master/d3/dc0/group__imgproc__shape.html
2. Search for "available statistics"

Expected behavior: a list of available statistics should be on the page. Best would be if the text linked there.
