RandomCropNearBBox

Targets:

image

mask

bboxes

keypoints

Image Types:uint8, float32

Crop around a reference bbox (cropping_bbox_key) with random shift (max_part_shift). Use when you have a region of interest to augment.

Arguments

max_part_shift

tuple[float, float] | float

[0,0.3]

Max shift in height and width dimensions relative to cropping_bbox dimension. If max_part_shift is a single float, the range will be (0, max_part_shift). Default (0, 0.3).

cropping_bbox_key

str

cropping_bbox

Additional target key for cropping box. Default cropping_bbox.

p

float

probability of applying the transform. Default: 1.

Examples

>>> aug = Compose([RandomCropNearBBox(max_part_shift=(0.1, 0.5), cropping_bbox_key='test_bbox')],
>>>              bbox_params=BboxParams("pascal_voc"))
>>> result = aug(image=image, bboxes=bboxes, test_bbox=[0, 5, 10, 20])
