DuplicateImageChecker

• Prints all duplicate images in a given directory by checking their color pixel values in a grid.
• Also recognizes images that are not the same exact size if their dimensions are mutiples from each other
• Prints all duplicate images and their sizes so you can decide which copy to keep.

Usecase

I use this tool to remove any duplicate images I got sent from other people in whatsapp.

Example

$ python main.py

Prüfe 21 Kombinationen im Ordner ./Testbilder
 - 1_1.jpg (186.171KB) und 1_2.jpg (186.171KB)
 - 3_high.jpg (207.322KB) und 3_low.jpg (207.322KB)
 - 4_original.jpg (6331.378KB) und 4_whatsapp.jpg (167.172KB)

• 1_1.jpg and 1_2.jpg are the same image
• 3_high.jpg and 3_low.jpg are the same image (both chewup up by whatsapp)
• 4_original.jpg and 4_whatsapp.jpg are the same image but only 4_whatsapp.jpg was compressed by whatsapp
