- Find duplicate images using perceptual hashing which can match similar images even if they have been resized, edited or had changes to their metadata (EXIF) tags, etc.
- Web interface for browsing images and deleting duplicates
- Machine learning analyzes the metadata of images you delete and suggests which images to delete
- Rapid rescanning of directories for new or changed files using database cache
- Images are not modified in any way
- Light weight Python code that can run on low-powered NAS devices
It may be necessary to set environment variables for the Wand to find the ImageMagick libraries.

Commands for organizing images into YYYY/MM/DD folders. src directory will be scanned recursively and files copied or moved into dest/YYYY/MM/DD directories based in DateTimeOriginal tag or FileModifyDate if DateTimeOriginal tag does not exist. The organize command will move the files in the destination in place. Use --dry-run option to test file actions.
./shashin.py cp src dest/
./shashin.py mv src dest/
./shashin.py organize dest/
The web interface should be served for local browsers only. There is no security and any external user could view or delete images. Additionally the complete path location of each image (ie. /Users/admin/photos/album/img_1.jpg) is exposed to the browser.
On scan, the dhash of each file is calculated and stored in an sqlite3 database. This database is used to detect identical files and similar images. By default, it is stored in ~/.cache/shashin/shashin.sqlite3
In the web interface, a group of duplicated images is ordered so that the FIRST image is the one predicted to be kept and the following images are to be deleted. The prediction is made by building a machine learning model comparing the metadata of images that were deleted with images that were kept. A new model is built every time the browse command is started.
- Handle videos
- Allow customization of
YYYY/MM/DDhierarchy - Allow renaming of files
