CABiNet (MobileNetV3-Large) Finetuned on UAVid

CABiNet (MobileNetV3-Large backbone) semantic segmentation model for aerial UAV imagery using the UAVid benchmark dataset.

This model is part of the UAVid Semantic Segmentation Model Zoo, a collection of CABiNet and YOLO26 models trained and evaluated under a common pipeline for aerial semantic segmentation.

Training Framework

Trained with the CABiNet repository, which pairs its own real-time segmentation trainer with a parallel Ultralytics YOLO26-sem pipeline — shared dataset tooling, training/eval, and mIoU benchmarking across UAVid, AeroScapes, and VDD. Star the repo if you find these models useful!

Known Limitations

Performance may degrade in:

Very small or thin objects (e.g. pedestrians, moving cars at altitude)
Heavy occlusion under tree canopy
Motion blur on moving vehicles
Mixed/very high input resolutions (UAVid source images are 3840x2160 / 4096x2160; both pipelines evaluate at reduced imgsz)
