A simple, fully convolutional model for real-time instance segmentation. This is the code for our paper:
For a real-time demo, check out our ICCV video:
Here are our YOLACT models along with their FPS on a Titan Xp and mAP on COCO's val
:
Image Size | GPU x BS | Backbone | *FPS | mAP | Weights | Configs | Download |
---|---|---|---|---|---|---|---|
550 | 1x8 | Resnet50-FPN | 42.5 | 29.0 | config | model | |
550 | 8x8 | Resnet50-FPN | 42.5 | 28.4 | config | model | |
550 | 1x8 | Resnet101-FPN | 33.5 | 30.4 | config | model |
*Note: The FPS is evaluated by the original implementation. When calculating FPS, only the model inference time is taken into account. Data loading and post-processing operations such as converting masks to RLE code, generating COCO JSON results, image rendering are not included.
All the aforementioned models are trained with a single GPU. It typically takes ~12GB VRAM when using resnet-101 as the backbone. If you want to try multiple GPUs training, you may have to modify the configuration files accordingly, such as adjusting the training schedule and freezing batch norm.
# Trains using the resnet-101 backbone with a batch size of 8 on a single GPU.
