Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
DBoW2 is primarily written in C++ and lacks native support for other languages, which can be a barrier for developers who are not proficient in C++.
Setting up DBoW2 requires detailed configuration of dependencies and environment settings, which can be time-consuming and error-prone.
The open-source project has a relatively small user base, leading to fewer contributions, bug fixes, and community-driven solutions for issues that arise.
