+# SeC: Advancing Complex Video Object Segmentation via Progressive Concept Construction

+[\[📦 Benchmark\]](https://huggingface.co/datasets/OpenIXCLab/SeCVOS)

+
+## Highlights
+
+- 🔥We introduce **Segment Concept (SeC)**, a **concept-driven** segmentation framework for **video object segmentation** that integrates **Large Vision-Language Models (LVLMs)** for robust, object-centric representations.
+- 🔥SeC dynamically balances **semantic reasoning** with **feature matching**, adaptively adjusting computational efforts based on **scene complexity** for optimal segmentation performance.
+- 🔥We propose the **Semantic Complex Scenarios Video Object Segmentation (SeCVOS)** benchmark, designed to evaluate segmentation in challenging scenarios.
