This is a clone of OpenCV (from commit 8808aaccffaec43d5d276af493ff408d81d4593c), modified to be cross-compiled on the ESP32. This Readme explains how to cross-compile on the ESP32 and also some details on the steps done.

Because the ESP32 has limited resources, it is a good idea to remove some parts of opencv that are in most cases not used.
