Bonjour,  
Pour mon projet j’effectue du traitement d’image avec la bibliothèque sensor, puis j’extrait chaque pixel un à un avec get\_pixel. Seulement le temps d’exécution du programme est de 10 secondes, pourquoi est-ce si long ? Comment le reduire ?

Hi, you don’t want to use get pixel to do any type of processing. You want to use our python methods. If you need to do pixel manipulation then you need to edit our C firmware.

We have a library of image processing methods that run C code internally: [image — machine vision — MicroPython 1.15 documentation](https://docs.openmv.io/library/omv.image.html)
