A bug

[EvilPerfectionist]

The images are loaded in the format of "RGB":

rpg_vid2e/upsampling/utils/dataset.py

Line 57 in b795a4d

img = img.convert('RGB')

But they are converted to "Gray" from "BGR" before writing to disk:

rpg_vid2e/upsampling/utils/upsampler.py

Line 98 in b795a4d

img = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)

This is not really a bug as the upsampled frames are only intended to be further processed into events (and only storing them in grayscale can save some disk space).

As you can see here, during the event generation process, the upsampled frames are only loaded as grayscale again:

rpg_vid2e/esim_torch/scripts/generate_events.py

Line 36 in ecbb11a

image = cv2.imread(image_file, cv2.IMREAD_GRAYSCALE)
