UFO is a simple and Unified framework for addressing Co-Object Segmentation tasks: Co-Segmentation, Co-Saliency Detection and Video Salient Object Detection. Humans tend to mine objects by learning from a group of images or a several frames of video since we live in a dynamic world. In computer vision area, many researches focus on co-segmentation (CoS), co-saliency detection (CoSD) and video salient object detection (VSOD) to discover the co-occurrent objects. However, previous approaches design different networks on these tasks separately, which lower the upper bound on the ease of use of deep learning frameworks. In this paper, we introduce a unified framework to tackle these issues, term as UFO (Unified Framework for Co-Object Segmentation). All tasks share the same framework.

Task & Framework

Usage

Requirement

torch >= 1.7.0
torchvision >= 0.7.0
python3

Training

Training on group-based images. We use COCO2017 train set with the provided group split dict.npy.

python main.py

Training on video (w/o flow) . We load the weight pre-trained on the static image dataset, and use DAVIS and FBMS to train our framework.

python finetune.py --model=models/image_best.pth --use_flow=False

Training on video (w/ flow). The same as above, then we use DAVIS_flow and FBMS_flow to train our network.

python finetune.py --model=models/image_best.pth --use_flow=True

Inference

Generate the image results [checkpoint]

python test.py --model=models/image_best.pth --data_path=CoSdatasets/MSRC7/ --output_dir=CoS_results/MSRC7 --task=CoS_CoSD

Generate the video results [checkpoint]

python test.py --model=models/video_best.pth --data_path=VSODdatasets/DAVIS/ --output_dir=VSOD_results/wo_optical_flow/DAVIS --task=VSOD

Generate the video results with optical flow [checkpoint]

python test.py --model=models/video_flow_best.pth --data_path=VSODdatasets/DAVIS_flow/ --output_dir=VSOD_results/w_optical_flow/w_optical_flow --use_flow=True --task=VSOD

Evaluation

• Pre-Computed Results: Please download the prediction results of our framework form the Results section.
• Evaluation Toolbox: We use the standard evaluation toolbox from COCA benchmark.

Result
