Detailed Description

Crop an image to the specified region of interest (ROI).

Function Documentation

cudaCrop() [1/7]

cudaError_t cudaCrop	(	float *	input,
		float *	output,
		const int4 &	roi,
		size_t	inputWidth,
		size_t	inputHeight
	)

Crop a floating-point grayscale image to the specified region of interest (ROI).

Parameters

[in]	input	Pointer to the input image in CUDA memory.
[out]	output	Pointer to the output image in CUDA memory. The output image should have the same dimensions as the ROI.
	roi	The region of interest from the input image that will be copied to the output image. This int4 vector forms a crop rectangle as follows:

• roi.x -> left
• roi.y -> top
• roi.z -> right
• roi.w -> bottom

The ROI coordinates must not be negative, otherwise an error will be returned.

Parameters

inputWidth	width of the input image (in pixels)
inputWidth	height of the input image (in pixels)

cudaCrop() [2/7]

cudaError_t cudaCrop	(	float3 *	input,
		float3 *	output,
		const int4 &	roi,
		size_t	inputWidth,
		size_t	inputHeight
	)

Crop a float3 RGB/BGR image to the specified region of interest (ROI).

Parameters

[in]	input	Pointer to the input image in CUDA memory.
[out]	output	Pointer to the output image in CUDA memory. The output image should have the same dimensions as the ROI.
	roi	The region of interest from the input image that will be copied to the output image. This int4 vector forms a crop rectangle as follows:

• roi.x -> left
• roi.y -> top
• roi.z -> right
• roi.w -> bottom

The ROI coordinates must not be negative, otherwise an error will be returned.

Parameters

inputWidth	width of the input image (in pixels)
