Fast image comparison and diffing in C++ (with a C# binding)
Inspired by resemble.js
Basically exactly the same functionality, just not JS. (i.e. faster, uses SSE2, small memory footprint)
Build bindings\ImageDiff for an easy to use C# binding.
Bitmap leftImg = new Bitmap(leftFile);
Bitmap rightImg = new Bitmap(rightFile);
using (DiffResult result = ImageDiff.Binding.Diff(leftImg, rightImg,
new DiffOptions()
{
ErrorColor = Color.FromArgb(255, 255, 0, 255),
Tolerance = 0.2f,
OverlayTransparency = 1.0f,
OverlayType = OverlayType.Movement,
WeightByDiffPercentage = false,
IgnoreColor = false
}))
{
result.Image.Save(diffFile);
Console.WriteLine(result.Similarity);
}
