This function converts the input array to xf::cv::Mat. The Vitis Vision kernel would require the input to be of type, xf::cv::Mat. This function would read from the array pointer and write into xf::cv::Mat based on the particular configuration (bit-depth, channels, pixel-parallelism) the xf::cv::Mat was created. Array2xfMat supports line stride. Line stride is the number of pixels which needs to be added to the address in the first pixel of a row in order to access the first pixel of the next row.
//Without Line stride support
template <int PTR_WIDTH, int MAT_T, int ROWS, int COLS, int NPC>
void Array2xfMat(ap_uint< PTR_WIDTH > *srcPtr, xf::cv::Mat<MAT_T,ROWS,COLS,NPC,XFCVDEPTH>& dstMat)
//With Line stride support
template <int PTR_WIDTH, int MAT_T, int ROWS, int COLS, int NPC>
void Array2xfMat(ap_uint< PTR_WIDTH > *srcPtr, xf::cv::Mat<MAT_T,ROWS,COLS,NPC,XFCVDEPTH>& dstMat, int stride)
| Parameter | Description |
|---|---|
| PTR_WIDTH | Data width of the input pointer. The value must be power 2, starting from 8 to 512. |
| MAT_T | Input Mat type. Example XF_8UC1, XF_16UC1, XF_8UC3 and XF_8UC4 |
| ROWS | Maximum height of image |
| COLS | Maximum width of image |
| NPC | Number of pixels computed in parallel. Example XF_NPPC1, XF_NPPC8 |
| XFCVDEPTH | Depth of the Output image. |
| srcPtr | Input pointer. Type of the pointer based on the PTR_WIDTH. |
| dstMat | Output image of type xf::cv::Mat |
| stride | Line stride. Default value is dstMat.cols |
