Find duplicates by content
This mode allows you to find, sort and move or delete duplicate photos based on their content.
Search of duplicates is performed in two stages. After you set the initial parameters, the program will perform a preliminary analysis of the photos. This process is performed only once and does not depend on the value of similarity. Speed image processing is about 10MB/sec.
The actual process of finding duplicates starts after you press Start button. The program sorts the duplicates by groups. In each group the most similar photos are placed. It is guaranteed that the leftmost picture is different from other photos no more, than you set in the similarity parameter. It should be noted that the similarity does not match pixel-area coincidence. It does not match the color palette. This is some integral parameter. Therefore, photos with different brightness, scale, orientation or even a black and white and color photos can be considered as similar photo. The program allows you to compare photos of different formats. Window is shown in the figure below.
