Color correction matrix - 2023.2 English

Color correction matrix algorithm converts the input image color format to output image color format using the colorcorrection matrix provided by the user (CCM_TYPE).

API Syntax

template <int CCM_TYPE, int SRC_T, int DST_T, int ROWS, int COLS, int NPC = 1, int XFCVDEPTH_IN_1 = _XFCVDEPTH_DEFAULT, int XFCVDEPTH_OUT_1 = _XFCVDEPTH_DEFAULT>
void colorcorrectionmatrix(xf::cv::Mat<SRC_T, ROWS, COLS, NPC, XFCVDEPTH_IN_1>& _src_mat,
                           xf::cv::Mat<SRC_T, ROWS, COLS, NPC, XFCVDEPTH_OUT_1>& _dst_mat)

Parameter Descriptions

The following table describes template parameters and arguments of the function.

Table 461 Table colorcorrectionmatrix correction Parameter Description
Parameter	Description
CCM_TYPE	colorcorrection matrix.
SRC_T	Input pixel type. 8/10/12/16-bit unsigned, 3 channel are supported (XF_8UC3, XF_10UC3, XF_12UC3, XF_16UC3).
DST_T	Output pixel type. 8/10/12/16-bit unsigned, 3 channel are supported (XF_8UC3, XF_10UC3, XF_12UC3, XF_16UC3).
ROWS	Maximum height of input and output image
COLS	Maximum width of input and output image. In case of N-pixel parallelism, width should be multiple of N.
NPC	Number of pixels to be processed per cycle; possible options is XF_NPPC1, XF_NPPC2 AND so on
XFCVDEPTH_IN_1	Depth of input image
XFCVDEPTH_OUT_1	Depth of output image
_src_mat	Input image
_dst_mat	Output image
