How do you compare two images for 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.

How do I find visually similar images?

With Google Images you can quickly discover visually similar images from around the web and obtain relative information about a photo including objects or places in it, and its metadata like the name of the object.

How do you compare two images and calculate relevance?

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.
