ImageDiff

Purpose

ImageDiff determines the differences between two images.

First input image	Second input image	Detected differences

You can tell it to ignore certain areas in the images. Choose some random color, cover up those areas in either of the images and supply the RGBA values of the selected color.

First input image	Second input image	Detected differences

Example

using Adrichem.ImageDiff;
using Adrichem.ImageDiff.Algorithms;

 var Image1 = new Bitmap(Image.FromFile(Test.Image1));
 var Image2 = new Bitmap(Image.FromFile(Test.Image2));

var Differ = new SimpleDiffer
{
    Options = new DiffOptions
    {
        IgnoreColor = Color.FromArgb(216, 0, 255),
    }
};

//OR

var Differ = new PerceptualDiffer
{
    Options = new PerceptualDiffOptions
    {
        IgnoreColor = Color.FromArgb(255, 216, 0),
        Threshold = 0.1f
    }
};
var DiffOutcome = Differ.Diff(Image1, Image2);
var ActualDiffImage = DiffOutcome.DiffImage;
ActualDiffImage.Save(Path.Combine(Path.GetTempPath(), Test.Name + "diff.png"));
