Below is a summary of the OpenCV features tested on the ESP32 and the time they took (adding the heap/stack used could also be useful).

Colorspaces
^^^^^^^^^^^
Opencv supports multiple colorspaces (RGB, BGR, RGB565, RGBA, CIELAB, CIEXYZ, Luv, YUV, HSV, HLS, YCrCb, Bayer, Gray). All these colorspaces are not mandatory for an embedded system, so some are removed.
