◆ operator()()

void roccv::Remap::operator()	(	hipStream_t	stream,
		const roccv::Tensor &	input,
		const roccv::Tensor &	output,
		const roccv::Tensor &	map,
		const eInterpolationType	inInterpolation,
		const eInterpolationType	mapInterpolation,
		const eRemapType	mapValueType,
		const bool	alignCorners,
		const eBorderType	borderType,
		const float4	borderValue,
		eDeviceType	device = eDeviceType::GPU
	)

Construct a new Remap object. The object can be used to remap the pixels in an image according to a new mapping given by a map tensor containing pixel coordinates.

Limitations:

Input: Supported TensorLayout(s): [NHWC, HWC] Channels: [1 , 3, 4] Supported DataType(s): [U8]

Output: Supported TensorLayout(s): [NHWC, HWC] Channels: [1 , 3, 4] Supported DataType(s): [U8]

Input/Output dependency:

  Property      |  Input == Output
 -------------- | -------------
  TensorLayout  | Yes
  DataType      | Yes
  Channels      | Yes
  Width         | Yes
  Height        | Yes
  Batch Size    | Yes

Currently supported remap types:

• REMAP_ABSOLUTE

Parameters

[in]	stream	The HIP stream to run this operation on.
[in]	input	Input tensor with image batch data
[out]	output	Output tensor for storing modified image batch data
[in]	map	Map tensor containing absolute or relative positions for how to remap the pixels of the input tensor to the output tensor
[in]	inInterpolation	Interpolation type to be used when getting values from the input tensor.
[in]	mapInterpolation	Interpolation type to be used when getting indices from the map tensor.
[in]	mapValueType	Determines how the values in the map are interpreted.
[in]	alignCorners	Set to true if corner values are aligned to center points of corner pixels and set to false if they are aligned by the corner points of the corner pixels.
[in]	borderType	A border type to identify the pixel extrapolation method (e.g. BORDER_TYPE_CONSTANT or BORDER_TYPE_REPLICATE)
[in]	borderValue	Set as 0 unless using a constant border.
[in]	device	The device which this operation should run on. (Default: eDeviceType::GPU)
