any one help me to find the solution of that by machine learning or any another approch?

Answer 1

EMGU.CV is same library in C# for openCV in C++ and python

you can use matchtemplate

In openCV it is

Mat image1Img = imread("image1.png", IMREAD_COLOR);
Mat image2Img = imread("image2.png", IMREAD_COLOR);
Mat image3Img = imread("image3.png", IMREAD_COLOR);

Mat scoreImg;
double maxScore;

matchTemplate(image1Img, image2Img, scoreImg, TM_CCOEFF_NORMED);
minMaxLoc(scoreImg, 0, &maxScore);
wxLogMessage(wxString::Format("score <%.2f>", maxScore));

In C# you can use as

Image<Gray, Byte> sourceImage = new Image<Gray, Byte>(@"Images/Source.bmp");
Image<Gray, Byte> templateImage = new Image<Gray, Byte>(@"Images/Template.bmp");
Image<Gray, float> resultImage = sourceImage.MatchTemplate(templateImage, Emgu.CV.CvEnum.TM_TYPE.CV_TM_CCOEFF_NORMED);
