Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
API requires Python-specific patterns and lacks comprehensive documentation for beginners.
Performance degrades significantly with larger image datasets due to memory constraints in numpy arrays.
GitHub issues are rarely addressed by maintainers, and the user community is not active.
Installation requires manual configuration of dependencies and environment variables which can be error-prone.
