and matrix type is match specified one too
|
| EnsureSizeIsEnough(Int32, Int32, MatType, GpuMat) |

|
| Filter2D |
Applies the non-separable 2D linear filter to an image.

| GaussianBlur(GpuMat, GpuMat, Size, Double, Double, BorderType, BorderType) | |
| GaussianBlur(GpuMat, GpuMat, Size, GpuMat, Double, Double, BorderType, BorderType, Stream) |
Smooths an image using the Gaussian filter.
|
| GetCudaEnabledDeviceCount |
Returns the number of installed CUDA-enabled devices.
Use this function before any other GPU functions calls.
If OpenCV is compiled without GPU support, this function returns 0.
|
| GetDevice |
Returns the current device index set by SetDevice() or initialized by default.
|
| Laplacian |
Applies the Laplacian operator to an image.
|
| MatchTemplate |
Computes a proximity map for a raster template and an image where the template is searched for.
|
| MinMaxLoc(GpuMat, Double, Double, Point, Point, GpuMat) |
Finds global minimum and maximum array elements and returns their values with locations
|
| MinMaxLoc(GpuMat, Double, Double, Point, Point, GpuMat, GpuMat, GpuMat) |
Finds global minimum and maximum array elements and returns their values with locations
|
| MorphologyEx(GpuMat, GpuMat, MorphologyOperation, Mat, NullablePoint, Int32) |
Applies an advanced morphological operation to an image.
|
| MorphologyEx(GpuMat, GpuMat, MorphologyOperation, Mat, GpuMat, GpuMat, NullablePoint, Int32, Stream) |
Applies an advanced morphological operation to an image.
|
| PrintCudaDeviceInfo | |
| PrintShortCudaDeviceInfo | |
| RegisterPageLocked |
Page-locks the matrix m memory and maps it for the device(s)
|
| ResetDevice |
Explicitly destroys and cleans up all resources associated with the current device in the current process.
Any subsequent API call to this device will reinitialize the device.
|
| Scharr(GpuMat, GpuMat, Int32, Int32, Int32, Double, BorderType, BorderType) |
Calculates the first x- or y- image derivative using the Scharr operator.
|
| Scharr(GpuMat, GpuMat, Int32, Int32, Int32, GpuMat, Double, BorderType, BorderType, Stream) |
