Bounding Box Prompt Image Segmentation With Adaptive Mask Refinement

via “bounding-box-prompt image segmentation with adaptive mask refinement”

Meta's foundation model for visual segmentation.

Unique: Encodes bounding boxes as dual corner points plus a learnable box token, allowing the same prompt encoder to handle points and boxes without separate branches. This design reuses the cross-attention mechanism, reducing model complexity while maintaining flexibility across prompt modalities.

vs others: More accurate than naive bounding box masking (e.g., connected components within box) because the transformer decoder understands object boundaries learned from 1.1B training images, handling occlusion and complex shapes within the box region.
