Sklearn structural_similarity
WebbThe structural similarity index measure (SSIM) is a method for predicting the perceived quality of digital television and cinematic pictures, as well as other kinds of digital images and videos.SSIM is used for measuring the similarity between two images. The SSIM index is a full reference metric; in other words, the measurement or prediction of image quality … WebbBased on the documentation cosine_similarity(X, Y=None, dense_output=True) returns an array with shape (n_samples_X, n_samples_Y).Your mistake is that you are passing [vec1, vec2] as the first input to the method. Also your vectors should be numpy arrays:. from sklearn.metrics.pairwise import cosine_similarity import numpy as np vec1 = …
