HELLO Smile | :)
this is my first question on CodeProject. actually, i dont post any question on any website but this time, i get STUCK !!
 
the IDEA...
i am working on a project based on image processing.
simply, i want to compare my new image with other images in my database to find the most similar images.
 
technically...
i am using (SURF) in (EMGU) warping library of OpenCV using this code:
 
// convert images to Gray images for the SURF
 
Image imgg1 = Image.FromFile("input_1.png");
Image<Gray, Byte> g_image_1 = new Image<Gray, byte>((Bitmap)imgg1);
Image imgg2 = Image.FromFile("input_0.png");
Image<Gray, Byte> g_image_2 = new Image<Gray, byte>((Bitmap)imgg2);
 
// prepare detection parameter 
 
MCvSURFParams image_param = new MCvSURFParams(300, false);
SURFDetector detect1 = new SURFDetector(image_param);
 
ImageFeature<float>[] image_feacher_1 = detect1.DetectFeatures(g_image_1, null);
ImageFeature<float>[] image_feacher_2 = detect1.DetectFeatures(g_image_2, null);
 
Features2DTracker<float> traker = new Features2DTracker<float>(image_feacher_1);
Features2DTracker<float>.MatchedImageFeature[] matching = traker.MatchFeature(image_feacher_2, 2);
 
matching = Features2DTracker<float>.VoteForUniqueness(matching ,0.8);
 
matching = Features2DTracker<float>.VoteForSizeAndOrientation(matching , 1.5, 20);
 
Image<Gray, Byte> res = g_image_1.ConcateVertical(g_image_2);
 
// drow matching lines
foreach (Features2DTracker<float>.MatchedImageFeature matchedFeature in matching )
            {
                PointF p = matchedFeature.ObservedFeature.KeyPoint.Point;
 
                p.Y += g_image_1.Height;
 
                res.Draw(new mLineSegment2DF(matchedFeature.SimilarFeatures[0].Feature.KeyPoint.Point, p), new Gray(0), 1);
            }
 
// showing the result image
ImageViewer Imagee = new ImageViewer(res);
Imagee.ShowDialog();
 

after this...
the result for images will be as matched points from both of the images...
and from 4570 point from image 1 and 4700 from image 2....
it matched 400 point and that.
 
now...
i am looking around to find the percentage of similarity between these images
but i can find it... i found something similar to my question...

but it is in C++ and the code hard to convert !!!
 
any help please !!!!!?!?!?
