- Add section explaining how margin works differently in multi-ref vs
margin-only matching, with examples showing why margin-only fails
when using multiple references per logo
- Update run_model_comparison.sh to use optimal threshold (0.70) and
margin (0.05) based on test results
- Add DINOv2 Large model test to comparison script
- Add threshold optimization test analysis to results document
- Add detailed explanation of mean vs max aggregation methods
- Include concrete example with Nike logo and 5 reference images
- Add decision table for when to use each approach
- Show how min_matching_refs works independently of aggregation
- 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
