Esp32 OpenCV tests

This example uses OpenCV library on the Esp32. Only the modules core, imgproc and imgcodecs are compiled.

The goal of this example is to check which OpenCV features are working.

The example tests :

  • some matrices initialization, then basic image processing functions on these matrices.
  • Reading a 470x400 pixels PNG image from the SPIFFS filesystem of the Esp32. For now, only PNG files are supported.
  • Perform grayscale conversion and then binary threshold on the image, then write it on the spi flash
  • Perform a canny edges detection on the image and the write it on the spi flash
