SAMURAI Refine

# SAMURAI Refine Node This node performs video object segmentation using the SAMURAI model. ## Inputs: - **image**: Input video frames sequence (required) - **model_name**: SAMURAI model to use (required) - **resolution**: Maximum resolution for processing (default: 1024) - **iou_threshold**: Intersection over Union threshold (default: 0.1) - **box**: Bounding box from SAMURAI Box Input (optional) - **points**: Point prompts for segmentation (optional) - **labels**: Labels for point prompts (optional) - **start_frame**: Starting frame number (optional) ## Outputs: - **MASK**: Generated segmentation masks - **frame_number**: Current frame number for sequence ## Models Available: - sam2.1_hiera_base.pt - sam2.1_hiera_base_plus.pt - sam2.1_hiera_large.pt - sam2.1_hiera_small.pt ## Usage: 1. Connect video and box/points inputs 2. Select desired model and parameters 3. Node will generate masks for the selected object through the video sequence
