Tunable options

You can configure parameters in function pixelate.

def pixelate(image: Union[str, np.ndarray],
             colors=10, factor=8, dither=False, quantize_by_factor=4,
             segmentation_network=None) -> dict

Just modify the line:

res = pixelate(img, segmentation_network=segm_net)

Future work

• move from bot.polling() to webhooks
• add heuristics for better pixel images
• replace face detection algorithm w/ instance segmentation
  (face detection only works if your subject is facing forward)
• replace white background w/ bg_color hyperparameter
