Detailed Description

Remaps the input image, effectively warping it using a user-provided mapping.

Function Documentation

VPIStatus vpiCreateImageRemap	(	VPIStream	stream,
		const VPIWarpMap *	warpMap,
		VPIPayload *	payload
	)

Create a payload for Image Remap algorithm.

This function allocates all resources needed by the Image Remap algorithm and ties the returned payload to the given stream.

Parameters

stream	[in] VPI stream the algorithm will be submitted to. Currently only PVA stream is supported.
warpMap	[in] Mapping of output into input. It must define a grid with the same size as output image.
payload	[out] Pointer to a payload handle with the create payload.

VPIStatus vpiSubmitImageRemap	(	VPIPayload	payload,
		VPIImage	input,
		VPIImage	output,
		VPIInterpolationType	interp,
		VPIBoundaryCond	bcond
	)

Submits the Image Remap operation to the stream associated with the payload.

Parameters

payload	[in] Payload created by vpiCreateImageRemap.
input	[in] Image to be remapped. In a lens distortion correction context, this would correspond to the distorted image. Valid image types: VPI_IMAGE_TYPE_NV12
output	[out] Stores the remapped image.. In a lens distortion correction context, this would correspond to the corrected (distortion-free) image. Must have the same type as input.
interp	[in] Interpolation method to be used. Valid values: VPI_INTERP_NEAREST VPI_INTERP_LINEAR VPI_INTERP_CATMULL_ROM
bcond	[in] What value to pick if remapped coordinated falls outside input image. Valid values: VPI_BOUNDARY_COND_ZERO
