SimilarImages is an advanced tool for finding duplicate or similar images on your computer. It can scan one or more folder location and find similar pictures based on several different scan methods. You can adjust the sensitivity by setting a threshold value that determines how much alike images need to be in order to be considered similar.

How does SimilarImages find those similar images?
It uses a somewhat modified version of the "Quadrant RGB" algorithm and futhermore considers some other meta-information provided by the source files. This basicially means: the images will be split into quadrants and average RGB values are computed. Pairs that have pretty "close" avg. numbers are considered being "similar". Movies are handled the same except that SimilarImages will first create a combined image using 4 frames from various points of the movie.

SimilarImages usually runs with the regular priority what means it will use as much CPU time as it can get, even if this means that other applications will run a lot slower. Using Low Priority Mode SimilarImages tells Windows to first consider other applications and only give "spare" CPU time to SimilarImages.
This will cause SimilarImages to take somewhat longer for its operations.
