Strengths & Weaknesses

↑ Strengths

Supports multiple programming languages and platforms.medium

Offers a wide range of computer vision algorithms.medium

High performance due to optimized C/C++ core.medium

↓ Weaknesses

Steep learning curve for non-Python developershigh

API requires Python-specific patterns, TypeScript SDK is community-maintained

Frequent breaking changes between versionsmedium

v0.1 to v0.2 migration required rewriting chain definitions

Limited support for high-level machine learning taskshigh

Does not natively support advanced deep learning models, requiring integration with TensorFlow or PyTorch

Complex setup and configuration on some platformsmedium

Windows users often face challenges with pre-built binaries and dependency management

Documentation can be sparse for advanced featureslow

Advanced topics such as custom algorithm development have limited tutorials and examples
