Required Methods

source

fn as_raw_GpuMatND(&self) -> *const c_void

Provided Methods

source

fn flags(&self) -> i32

! includes several bit-fields:

the magic signature
continuity flag
depth
number of channels

source

fn dims(&self) -> i32

matrix dimensionality

source

fn size(&self) -> Vector<i32>

shape of this array

source

fn step(&self) -> Vector<size_t>

! step values Their semantics is identical to the semantics of step for Mat.

source

fn try_clone(&self) -> Result<GpuMatND>

Creates a full copy of the array and the underlying data. The method creates a full copy of the array. It mimics the behavior of Mat::clone(), i.e. the original step is not taken into account. So, the array copy is a continuous array occupying total()*elemSize() bytes.

source

fn clone_1(&self, stream: &mut Stream) -> Result<GpuMatND>

Creates a full copy of the array and the underlying data. The method creates a full copy of the array. It mimics the behavior of Mat::clone(), i.e. the original step is not taken into account. So, the array copy is a continuous array occupying total()*elemSize() bytes.

Overloaded parameters

This overload is non-blocking, so it may return even if the copy operation is not finished.

source

fn create_gpu_mat_header(
    &self,
    idx: GpuMatND_IndexArray,
    row_range: Range,
    col_range: Range
) -> Result<GpuMat>

Creates a GpuMat header for a 2D plane part of an n-dim matrix.

Note: The returned GpuMat is constructed with the constructor for user-allocated data. That is, It does not perform reference counting.

Note: This function does not increment this GpuMatND’s reference counter.

source

fn create_gpu_mat_header_1(&self) -> Result<GpuMat>

Creates a GpuMat header for a 2D plane part of an n-dim matrix.

Note: The returned GpuMat is constructed with the constructor for user-allocated data. That is, It does not perform reference counting.

Note: This function does not increment this GpuMatND’s reference counter.

Overloaded parameters

Creates a GpuMat header if this GpuMatND is effectively 2D.

Note: The returned GpuMat is constructed with the constructor for user-allocated data. That is, It does not perform reference counting.

Note: This function does not increment this GpuMatND’s reference counter.

source

fn to_gpu_mat(&self) -> Result<GpuMat>

Extracts a 2D plane part of an n-dim matrix if this GpuMatND is effectively 2D. It differs from createGpuMatHeader() in that it clones a part of this GpuMatND.

Note: This operator does not increment this GpuMatND’s reference counter;
