Input is RGB or BGR? #37

Hi @guipotje I have another question. In the training code you use cv2.imread to read images. However, the default image read is BGR color mode. Is it a bug?

Hi @noahzn, actually, we use grayscale images, look here, we average channels, so it should make little to no difference in using RGB or BGR.
