Bug ID: 498281
Summary: No faces detected: -215:Assertion failed)
inputs[vecIdx][j] == inputs[i][j] in function
'getMemoryShapes'
Classification: Applications
Product: digikam
Version: 8.5.0
Platform: Debian testing
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Faces-Engine
Assignee: digikam-bugs-n...@kde.org
Reporter: bugs.kde@knackich.de
Target Milestone: ---
SUMMARY
When running face detection on an album with photos with people’s faces
visible, no faces are detected. This error is logged:
[ERROR:0@14,429] global ./modules/dnn/src/net_impl.cpp (1184)
getLayerShapesRecursively Exception message: OpenCV(4.6.0)
./modules/dnn/src/layers/eltwise_layer.cpp:251: error: (-215:Assertion failed)
inputs[vecIdx][j] == inputs[i][j] in function 'getMemoryShapes'
STEPS TO REPRODUCE
1. Start digikam from a terminal
2. Right-click on an album and select “Scan for Faces”
OBSERVED RESULT
No faces are detected.
Face detection appears to be starting. The progress bar shows that photos are
processed one by one. In the end a popup appears:
Items scanned for faces: 4 Faces processed: 0
Where “4” is the number of photos in the album and “Faces processed” is always
0.
These messages are logged once for every photo:

EXPECTED RESULT
Faces should be detected and known persons should be recognized if possible.
