Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
Primary language is C++, which may not be familiar to all developers, and while there are bindings for other languages like Python, they are less mature.
Setting up the environment can be challenging due to dependencies on external libraries and tools that need proper configuration.
While basic tutorials exist, detailed explanations of more complex functionalities are lacking, making it difficult for users to fully leverage the library's capabilities.
Real-time processing can become sluggish when dealing with high-resolution or large volumes of gesture data, impacting the responsiveness and accuracy of recognition systems.
