All comparers can be registered:

VerifyImageHash.RegisterComparers();

Use specific threshold

[Test]
public Task CompareImageThreshold() =>
    VerifyFile("sample.jpg")
        .UseImageHash(threshold: 85);

^{snippet source | anchor}

Use specific algorithm

[Test]
public Task CompareImageAlgorithm() =>
    VerifyFile("sample.jpg")
        .UseImageHash(algorithm: new PerceptualHash());

^{snippet source | anchor}
