Warning
This operator is now deprecated. Use
random_bbox_crop()
instead.Performs a random crop with bounding boxes where Intersection Over Union (IoU) meets a randomly selected threshold between 0-1.
When the IoU falls below the threshold, a new random crop is generated up to num_attempts. As an input, the operator accepts image, bounding boxes and labels. At the output cropped image, cropped and valid bounding boxes and valid labels are returned.

- Parameters:
- Keyword Arguments:
bytes_per_sample_hint¶ (int or list of int, optional, default = [0]) –
Output size hint, in bytes per sample.
If specified, the operator’s outputs residing in GPU or page-locked host memory will be preallocated to accommodate a batch of samples of this size.
num_attempts¶ (int, optional, default = 1) – Number of attempts.
preserve¶ (bool, optional, default = False) – Prevents the operator from being removed from the graph even if its outputs are not used.
seed¶ (int, optional, default = -1) –
Random seed.
If not provided, it will be populated based on the global seed of the pipeline.
