  Why:

  CURRENT

  The README currently starts with the H1 and then 'This is the official pytorch implementation...'.

  Accurately segmenting objects in images is a fundamental challenge in computer vision, especially when objects are heavily occluded. BCNet addresses this critical problem by introducing a novel bilayer network design that explicitly models occluder and occludee relationships, leading to significant improvements in instance segmentation performance under occlusion.

  Refactor 'Highlights' into a 'Key Features' section for better scannability

  Why:

  CURRENT

  Highlights
  BCNet:** Two/one-stage (detect-then-segment) instance segmentation with state-of-the-art performance.
  Novelty:** A new mask head design, explicit occlusion modeling with **bilayer decouple (object boundary and mask)** for the occluder and occludee in the same RoI.
  Efficacy:** Large improvements both the FCOS (anchor-free) and Faster R-CNN (anchor-based) detectors.
  Simple:** Small additional computation burden and easy to use.

  ## Key Features
  *   **State-of-the-art Instance Segmentation:** BCNet achieves top performance in two/one-stage (detect-then-segment) instance segmentation.
  *   **Novel Occlusion Modeling:** Introduces a new mask head design with explicit bilayer decoupling for occluder and occludee in the same RoI.
  *   **Enhanced Boundary Detection:** Improves object contour and mask predictions through specialized GCN layers for occluder and occludee.
  *   **Broad Compatibility:** Demonstrates large improvements with both FCOS (anchor-free) and Faster R-CNN (anchor-based) detectors.
  *   **Computational Efficiency:** Offers significant performance gains with small additional computational burden and is easy to use.
