The Making and Breaking of Camouflage

Dataset Preparation Steps

<ol> <li>Crop the images around the camouflaged animal so that only its immediate surrounding area is taken into account:

For a still image dataset:

python utils/crop.py --data_dir ../datasets/CHAMELEON --out_data_dir ../datasets/CHAMELEON_crop --type still

For a video dataset:

python utils/crop.py --data_dir ../datasets/MoCA_Video/TrainDataset_per_sq/ --out_data_dir ../datasets/Moca_Video_Train_crop --type video

</li> <li> To compute the boundary score and the combined score, generate global contours (for the cropped images) and ground truth contours (for the object of interest, using the mask) with an off-the-shelf contour detection method, e.g. [DexiNed](https://github.com/xavysp/DexiNed).</li> <li> Compute camouflage scores</li>

python eval.py --data_dir ../CHAMELEON_crop/ --type still --contour_path ../DexiNed/result/BIPED2CHAM/fused/ --contour_gt_path ../DexiNed/result/BIPED2CHAM-GT/fused/

</ol>

Probabilistic scoring functions and more implementation will be added soon.
