- Update DetectLogosDETR to support both CLIP and DINOv2 models
- Rename clip_model parameter to embedding_model
- Add model type detection for different embedding extraction
- DINOv2 uses CLS token, CLIP uses get_image_features()
- Add -e/--embedding-model argument to test_logo_detection.py
- Include model name in file output header
- Add run_threshold_tests.sh for testing various threshold/margin values
- Add run_model_comparison.sh for comparing CLIP vs DINOv2 models
- Add find_all_matches() method to DetectLogosDETR that returns all
logos above similarity threshold without any rejection logic
- Add --matching-method simple option to test script
- Update run_comparison_tests.sh to include simple matching as Test 1
- Update documentation to describe simple matching method
The multi-ref matching method was missing a margin check against other
logos, causing excessive false positives. This fix adds:
- margin parameter to find_best_match_multi_ref() that requires the
best logo's score to exceed the second-best by a minimum margin
- Test script now passes --margin to both matching methods
- Updated documentation to reflect margin applies to both methods
Also adds run_comparison_tests.sh to run all three matching methods
and compare results.
Add DETR+CLIP based logo detection library and test framework:
- DetectLogosDETR class for logo detection and matching
- Test script with margin-based and multi-ref matching methods
- Data preparation script for test database
- Documentation for API usage and test methodology
