#include <opencv2/cudaarithm.hpp>
Forms a border around an image.
src | Source image. CV_8UC1 , CV_8UC4 , CV_32SC1 , and CV_32FC1 types are supported. |
dst | Destination image with the same type as src. The size is Size(src.cols+left+right, src.rows+top+bottom) . |
top | Number of top pixels |
bottom | Number of bottom pixels |
left | Number of left pixels |
right | Number of pixels in each direction from the source image rectangle to extrapolate. For example: top=1, bottom=1, left=1, right=1 mean that 1 pixel-wide border needs to be built. |
borderType | Border type. See borderInterpolate for details. BORDER_REFLECT101 , BORDER_REPLICATE , BORDER_CONSTANT , BORDER_REFLECT and BORDER_WRAP are supported for now. |
value | Border value. |
stream | Stream for the asynchronous version. |
Ptr<LookUpTable> cv::cuda::createLookUpTable | ( | InputArray | lut | ) |
#include <opencv2/cudaarithm.hpp>
Creates implementation for cuda::LookUpTable .
lut | Look-up table of 256 elements. It is a continuous CV_8U matrix. |

src | Source matrix. Supports 1, 3 and 4 channels images with CV_8U, CV_16U, CV_32S or CV_32F depth. |
dst | Destination matrix. |
flipCode | Flip mode for the source:
