class Similarity – Similarity Object

The similarity object is an attrtuple returned by Image.get_similarity().

Fields are accessible by name (similarity.mean) or by index (similarity[0]). It has no public constructor.

class image.similarity

Please call Image.get_similarity() to create this object.

mean() → float

Returns the mean of the similarity values computed across the image.

Also accessible as similarity[0].

stdev() → float

Returns the standard deviation of the similarity values computed across the image.

Also accessible as similarity[1].

min() → float

Returns the min of the similarity values computed across the image. For SSIM threshold the min value to determine if two images are different.

Also accessible as similarity[2].

max() → float

Returns the max of the similarity values computed across the image. For DSIM threshold the max value to determine if two images are different.

Also accessible as similarity[3].
