default constructor

Overloaded parameters

Parameters

• size: Array of integers specifying an n-dimensional array shape.
• type: Array type. Use CV_8UC1, …, CV_16FC4 to create 1-4 channel matrices, or CV_8UC(n), …, CV_64FC(n) to create multi-channel (up to CV_CN_MAX channels) matrices.

pub fn new_1(

    data: *mut c_void,
    step: GpuMatND_StepArray
) -> Result<GpuMatND>

default constructor

Overloaded parameters

Parameters

• size: Array of integers specifying an n-dimensional array shape.
• type: Array type. Use CV_8UC1, …, CV_16FC4 to create 1-4 channel matrices, or CV_8UC(n), …, CV_64FC(n) to create multi-channel (up to CV_CN_MAX channels) matrices.
• data: Pointer to the user data. Matrix constructors that take data and step parameters do not allocate matrix data. Instead, they just initialize the matrix header that points to the specified data, which means that no data is copied. This operation is very efficient and can be used to process external data using OpenCV functions. The external data is not automatically deallocated, so you should take care of it.
• step: Array of _size.size()-1 steps in case of a multi-dimensional array (the last step is always set to the element size). If not specified, the matrix is assumed to be continuous.

C++ default parameters

• step: StepArray()

fn as_raw_mut_GpuMatND(&mut self) -> *mut c_void

fn flags(&self) -> i32

! includes several bit-fields:

fn set_flags(&mut self, val: i32)

! includes several bit-fields:

fn dims(&self) -> i32

matrix dimensionality

fn set_dims(&mut self, val: i32)

matrix dimensionality

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

shape of this array

fn set_size(&mut self, val: GpuMatND_SizeArray)

shape of this array

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

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

fn set_step(&mut self, val: GpuMatND_StepArray)

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

fn create(&mut self, size: GpuMatND_SizeArray, typ: i32) -> Result<()>

Allocates GPU memory. Suppose there is some GPU memory already allocated. In that case, this method may choose to reuse that GPU memory under the specific condition: it must be of the same size and type, not externally allocated, the GPU memory is continuous(i.e., isContinuous() is true), and is not a sub-matrix of another GpuMatND (i.e., isSubmatrix() is false). In other words, this method guarantees that the GPU memory allocated by this method is always continuous and is not a sub-region of another GpuMatND.

fn release(&mut self) -> Result<()>

fn swap(&mut self, m: &mut GpuMatND)

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.

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.

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.

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

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

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.

fn upload(&mut self, src: &dyn ToInputArray) -> Result<()>

fn upload_1(
    &mut self,
    src: &dyn ToInputArray,
    stream: &mut Stream

fn download(&self, dst: &mut dyn ToOutputArray) -> Result<()>

fn download_1(
    &self,
    dst: &mut dyn ToOutputArray,
    stream: &mut Stream
) -> Result<()>

fn is_continuous(&self) -> Result<bool>

returns true iff the GpuMatND data is continuous (i.e. when there are no gaps between successive rows)

fn is_submatrix(&self) -> Result<bool>

returns true if the matrix is a sub-matrix of another matrix

fn elem_size(&self) -> Result<size_t>

returns element size in bytes

fn elem_size1(&self) -> Result<size_t>

returns the size of element channel in bytes

fn empty(&self) -> Result<bool>

returns true if data is null

fn external(&self) -> Result<bool>

returns true if not empty and points to external(user-allocated) gpu memory

fn get_device_ptr(&self) -> Result<&mut u8>

returns pointer to the first byte of the GPU memory

fn total(&self) -> Result<size_t>

returns the total number of array elements

fn total_mem_size(&self) -> Result<size_t>

returns the size of underlying memory in bytes

fn typ(&self) -> Result<i32>

returns element type
