Deprecations

ImageCompression

Old way:

transform = A.Compose([A.ImageCompression(
  quality_lower=75,
  quality_upper=100,
  p=0.5
)])

New way:

transform = A.Compose([A.ImageCompression(
  quality_range=(75, 100),  
  p=0.5
)])

Downscale

Old way:

transform = A.Compose([A.Downscale(
  scale_min=0.25,
  scale_max=1,
  interpolation= {"downscale": cv2.INTER_AREA, "upscale": cv2.INTER_CUBIC},
  p=0.5
)])

New way:

transform = A.Compose([A.Downscale(
  scale_range=(0.25, 1),
 interpolation_pair = {"downscale": cv2.INTER_AREA, "upscale": cv2.INTER_CUBIC},  
  p=0.5
)])

As of now both ways work and will provide the same result, but old functionality will be removed in later releases.

Improvements

• Buggix in Blur.
• Bugfix in bbox clipping, it could be not intuitive, but boxes should be clipped by height, width and not height - 1, width -1 by @ternaus
• Allow to compose only keys, that are required there. Any extra unnecessary key will give an error by @ayasyrev
• In PadIfNeeded if value parameter is not None, but border mode is reflection, border mode is changed to cv2.BORDER_CONSTANT by @ternaus
