What needs to be clarified
Assess suitability for facial comparison, separate glasses from appearance features and evaluate visible facial information without assuming an identity.
Materials to prepare
- Original entrance footage including neighbouring frames
- Comparison photographs without resizing or further compression
- Image provenance and file-processing information
What to compare
Select frames with the clearest facial regions while preserving their link to the original. Compare visible morphology, allowing for lens reflections, occlusion and detail. Describe frame resemblance separately and assess whether enough facial information remains for meaningful comparison.
Possible outcome of the analysis
The result may assess suitability and feasible comparisons with feature illustrations; insufficient detail should lead to an explanation of why identity cannot be determined.
Limits of the conclusions
The same glasses model does not identify its wearer. Enlargement cannot restore lost detail; hidden eyes and blurred contours may preclude a supported identity conclusion.
