Public Functions

BorderVarShapeWrapNHWC() = default

inline explicit __host__ __device__ BorderVarShapeWrapNHWC (ImageBatchWrapper imageBatchWrap, ValueType borderValue={})

Constructs a BorderVarShapeWrapNHWC by wrapping an imageBatchWrap.

Parameters:

• imageBatchWrap – [in] An ImageBatchVarShapeWrapNHWC object to be wrapped.

• borderValue – [in] The border value is ignored in non-constant border types.

inline explicit __host__ BorderVarShapeWrapNHWC(const ImageBatchVarShapeDataStridedCuda &images, int numChannels, ValueType borderValue = {})

Constructs a BorderVarShapeWrapNHWC by wrapping images.

Parameters:

• images – [in] A ImageBatchVarShapeDataStridedCuda with image batch information.

• numChannels – [in] The number of (interleaved) channels inside the wrapper.

• borderValue – [in] The border value is ignored in non-constant border types.

inline __host__ __device__ ValueType & operator[] (int4 c) const

Subscript operator for read-only or read-and-write access (depending on value type).

Parameters:

c – [in] 4D coordinates (x sample, y row, z col, w channel) to be accessed.

Returns:

Accessed (const) reference.

inline __host__ __device__ ValueType & operator[] (int3 c) const

Subscript operator for read-only or read-and-write access (depending on value type, considering plane=0).

Parameters:

c – [in] 3D coordinates (x sammple, y row, z col) (first channel) to be accessed.

Returns:

Accessed (const) reference.

inline __host__ __device__ ValueType * ptr (int s, int y, int x, int c) const

Get a read-only or read-and-write proxy (as pointer) at the given coordinates.

Parameters:

• s – [in] Sample image index in the list.

• y – [in] Row index in the selected image.

• x – [in] Column index in the selected image.

• c – [in] Channel index in the image.

Returns:

The (const) pointer to the beginning of the given coordinates.

inline __host__ __device__ ValueType * ptr (int s, int y, int x) const

Get a read-only or read-and-write proxy (as pointer) at the given coordinates (considering plane=0).

Parameters:

• s – [in] Sample image index in the list.

• y – [in] Row index in the selected image.

• x – [in] Column index in the selected image.

Returns:

The (const) pointer to the beginning of the given coordinates.
