The Random Crop Images node randomly selects a rectangular section from each input image and crops it to a specified width and height. This is commonly used for data augmentation to create variations of training images. The random position for the crop is determined by a seed value, ensuring the same crop can be reproduced.

Inputs

Parameter	Data Type	Required	Range	Description
image	IMAGE	Yes	-	The image to be cropped.
width	INT	No	1 - 8192	The width of the crop area (default: 512).
height	INT	No	1 - 8192	The height of the crop area (default: 512).
seed	INT	No	0 - 18446744073709551615	A number used to control the random position of the crop (default: 0).

Note: The width and height parameters must be less than or equal to the dimensions of the input image. If a specified dimension is larger than the image, the crop will be limited to the image’s boundary.

Outputs

Output Name	Data Type	Description
image	IMAGE	The resulting image after the random crop has been applied.
