Key Highlights

  • Fisheye cameras support in camera calibration block
  • Heatmap block for detections and tracklets
  • Enable gzip compression by default
  • Fix video frame count estimation from uploaded video
  • Add frame size to WebRTC video metadata
  • SAM3 visual segmentation enabled

New Features

  • Fisheye camera calibration
  • Heatmap visualization block (supports detections and tracklets with movement tracking)

Full Release Notes

# 💪 Added

* Fisheye cameras in camera calibration block by @Erol444 in https://github.com/roboflow/inference/pull/1996
Calibration block was supporting polynomial calibration which is not handling fisheye distortions well. This change adds support for fisheye calibration.

* Heatmap block by @Erol444 in https://github.com/roboflow/inference/pull/1986
This change adds heatmap block (uses supervision's heatmap annotator), which supports both:
 - detections, so heatmap based on where detections were
 - tracklets, which ignores stationary objects (default: on), so we heatmap the movements not the objects
