Convert hppiMatrix to Mat.
This function allocates and initializes new matrix (if needed) that has the same size and type as input matrix. Supports CV_8U, CV_16U, CV_16S, CV_32S, CV_32F, CV_64F.
- Parameters
-
src | input hppiMatrix. |
dst | output matrix. |
accel | accelerator instance (see hpp::getHpp for the list of acceleration framework types). |
cn | number of channels. |

Create hppiMatrix from Mat.
This function allocates and initializes the hppiMatrix that has the same size and type as input matrix, returns the hppiMatrix*.
If you want to use zero-copy for GPU you should to have 4KB aligned matrix data. See details hppiCreateSharedMatrix.
Supports CV_8U, CV_16U, CV_16S, CV_32S, CV_32F, CV_64F.
- Note
- The hppiMatrix pointer to the image buffer in system memory refers to the src.data. Control the lifetime of the matrix and don't change its data, if there is no special need.
- Parameters
-
src | input matrix. |
accel | accelerator instance. Supports type:
- HPP_ACCEL_TYPE_CPU - accelerated by optimized CPU instructions.
- HPP_ACCEL_TYPE_GPU - accelerated by GPU programmable units or fixed-function accelerators.
- HPP_ACCEL_TYPE_ANY - any acceleration or no acceleration available.
