How is mutual information calculated?
The mutual information can also be calculated as the KL divergence between the joint probability distribution and the product of the marginal probabilities for each variable. — Page 57, Pattern Recognition and Machine Learning, 2006. This can be stated formally as follows: I(X ; Y) = KL(p(X, Y) || p(X) * p(Y))
What is mutual information image?
Mutual information is a measure of image matching, that does not require the signal to be the same in the two images. It is a measure of how well you can predict the signal in the second image, given the signal intensity in the first.
How do you measure similarity between two images?
Image Similarity
The similarity of the two images is detected using the package “imagehash”. If two images are identical or almost identical, the imagehash difference will be 0. Two images are more similar if the imagehash difference is closer to 0.
What is similarity in image processing?
These measure provide a quantitative measure of the degree of match between two images, or image patches, A and B. Image similarity measures play an important role in many image fusion algorithms and applications including retrieval, classification, change detection, quality evaluation and registration.
