Softwares

• line/lighthouse, A user-friendly library for reproducible video moment retrieval and highlight detection (MR-HD). It supports six models, three features, and five datasets. In addition, we prepare an inference-only API and demo for developers to use MR-HD methods easily.
• Shutoh, A fast scene detector implemented in C++20. Inspired by PySceneDetect, Shutoh aims to provide a powerful and flexible alternative with enhanced performance. Shutoh achieves 2x~4x faster than PySceneDetect and supports not only rule-based (PySceneDetect), but also ML-based and neural-based scene detectors.
