Reconnaissance d'un vrai sémaphore avec YOLO Darknet

Ce sémaphore est une image virtuelle, mais c'est copie conforme du vrai !

Suite et fin

De Yolo Darknet sur un portable Optimus

Apprentissage

cfg

Relire tout le readme pour bien configurer en particulier:

  • for training for both small and large objects use modified models: yolov3-tiny_3l.cfg
  • If you train the model to distinguish Left and Right objects as separate classes (left/right hand, left/right-turn on road signs, …) then for disabling flip data augmentation - add flip=0

Apprentissage
