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 compare two images in image processing?

The general idea is very simple - pixel-by-pixel comparison. The comparison engine gets the color of pixels that have the same coordinates within the image and compares this color. If the color of each pixel of both images coincides, TestComplete considers the two images to be identical.
