[06/17/2022] Now, fast inference mode offers a salient object result with the mask.
We have improved a result quality of salient object as follows.
You can get the more clear salient object by tuning the threshold. We will release initializing TRACER with a version of pre-trained TE-x.

[04/20/2022] We update a pipeline for custom dataset inference w/o measuring.

• Run main.py scripts.

python main.py inference --dataset custom_dataset/ --arch 7 --img_size 640 --save_map True

• Pre-trained models of TRACER are available at here
• Change the model name as 'best_model.pth' and put the weights to the path 'results/DUTS/TEx_0/best_model.pth'
  (here, the x means the model scale e.g., 0 to 7).
• Input image sizes for each model are listed belows.

--arch: EfficientNet backbone scale: TE0 to TE7.
--frequency_radius: High-pass filter radius in the MEAM.
--gamma: channel confidence ratio \gamma in the UAM.
--denoise: Denoising ratio d in the OAM.
--RFB_aggregated_channel: # of channels in receptive field blocks.
--multi_gpu: Multi-GPU learning options.
--img_size: Input image resolution.
--save_map: Options saving predicted mask.
