+### Grounded-SAM-2  Video Object Tracking with Continuous ID (with Grounding DINO)
+Users can upload their own video files and specify custom text prompts for grounding and tracking using the Grounding DINO and SAM 2 frameworks. To do this, execute the script:
+
+
+```python 
+grounded_sam2_tracking_demo_with_continuous_id.py
+```
+
+You can customize various parameters including:
+
+- `text`: The grounding text prompt.
+- `video_dir`: Directory containing the video files.
+- `output_dir`: Directory to save the processed output.
+- `output_video_path`: Path for the output video.
+- `step`: Frame stepping for processing.
+- `box_threshold`: box threshold for groundingdino model
+- `text_threshold`: text threshold for groundingdino model
+Note: This method supports only the mask type of text prompt.
