Image processing 12- image linear blending

Linear blending of two images

    

    Perform a linear blending of the two images ：

        dst(i,j)=weights1(i,j)∗src1(i,j)+weights2(i,j)∗src2(i,j)

void cv::blendLinear(InputArray src1,

                InputArray src2,

                InputArray weights1,

                InputArray weights2,

                OutputArray dst

                )

    src1 : The type is CV_8UC(n) or CV_32FC(n), among n As a positive integer .

    src2 : It is associated with src1 Of the same type and size .

    weights1: The type is CV_32FC1, And src1 Same size .

    weights2; The type is CV_32FC1, And src1 Same size .

    dst ： If its size and type are the same as src1 Different , Then create it .
