1.9.0 "Find similar files" can't distinguish down-converted copies of HEIC file

[rsbrux]

"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".

See the hyperlinked text "this directory" in my original post.

Thanks to your detailed description I can reproduce the problem.

This problem is supposed to be fixed in XnView MP 1.9.2. Please check and confirm the bug fix here.
