1.9.0 "Find similar files" can't distinguish down-converted copies of HEIC file
Posted: Mon May 26, 2025 9:18 am
"FInd similar files" is unreliable when examining photos converted from HEIC to JPG
Effect: duplicate photos are not identified.
To reproduce:
1. Open this directory in XnView MP.
2. Click on "Tools" - "Find similar files".
3. Select "Similar image content".
4. Set similarity to 60%.
5. Click "OK".
Actual behaviour (bug): XnView reports "No files found!"
The files ending in "IMG_NNNN.jpg" (5712x3213) were converted from the original Apple HEIC format into JPG using XnViewMP's batch conversion feature.
Those without "IMG_NNNN" (2730x1536) were converted by Apple for inclusion in a "Shared album".
Effect: duplicate photos are not identified.
