How to compare 2 images in Python?

Python - OpenCV & PyQT5 together

To compare two images, we use the Mean Square Error (MSE) of the pixel values of the two images. Similar images will have less mean square error value. Using this method, we can compare two images having the same height, width and number of channels.

How to find correlation coefficient between two images in Python?

All Answers (3) This function is used to compute the correlation (coefficient) between two pictures (matrices): r = corr2(A,B) computes the correlation coefficient between A and B, where A and B are identical matrices or vectors.

What is correlation in image?

1 Digital image correlation. Digital image correlation (DIC) is an optical technique that combines image registration and tracking methods for accurate 2D measurements of changes in images. Correlation theories for the measurement of alterations in data were first applied to digital images in 1975 [316].
