[C#/WINFORM/EMGUCV] Image 클래스 : Convolution 메소드를 사용해 볼록 회선 적용하기

■ Image 클래스의 Convolution 메소드를 사용해 볼록 회선을 적용하는 방법을 보여준다.

▶ 예제 코드 (C#)


using Emgu.CV;
using Emgu.CV.Structure;

float[,] maskArray =
{
    {  0.0f, -1.0f, 0.0f },
    { -1.0f,  0.0f, 1.0f },
    {  0.0f,  1.0f, 0.0f }
};

ConvolutionKernelF convolutionKernelF = new ConvolutionKernelF(maskArray);

Image<Gray, float> sourceImage = new Image<Gray, float>("c:\\source.jpg");
Image<Gray, float> targetImage = sourceImage.Convolution(convolutionKernelF);

sourceImageBox.Image = sourceImage;
targetImageBox.Image = targetImage;
