We introduce a novel training protocol named Weakly Semi-Supervised Camouflaged Object Detection (WSSCOD), utilizing boxes as prompts to generate high-quality pseudo labels. WSSCOD leverages box annotations, complemented by a minimal amount of pixel-level annotations, to generate high-accuracy pseudo labels.

1. Dataset Division:

   • $\mathcal{D}_m = {\mathcal{X}_m, \mathcal{F}_m, \mathcal{B}m}{m=1}^M$: Pixel-level annotations $\mathcal{F}_m$, box annotations $\mathcal{B}_m$, and training images $\mathcal{X}_m$.
   • $\mathcal{D}_n = {\mathcal{X}_n, \mathcal{B}n}{n=1}^N$: Box annotations and images, where $M+N$ represents the number of training sets.

2. Training ANet:

   • Train ANet using dataset $\mathcal{D}_m$.
   • Use $\mathcal{B}_m$ as prompts and $\mathcal{F}_m$ for supervision.

3. Generating Pseudo Labels:

   • Use the trained ANet and dataset $\mathcal{D}_n$ to predict pseudo labels $\mathcal{W}_n$.

4. Constructing the Weakly Semi-Supervised Dataset:

   • Combine ${\mathcal{X}_m, \mathcal{F}m}{m=1}^M$ and ${\mathcal{X}_n, \mathcal{W}n}{n=1}^N$ to form $\mathcal{D}_t$.

5. Training PNet:

   • Train PNet using the dataset $\mathcal{D}_t$.
   • Evaluate performance with different $M$ and $N$ ratios:
     • PNet$_{F1}$: $M=1%$, $N=99%$
     • PNet$_{F5}$: $M=5%$, $N=95%$
     • PNet$_{F10}$: $M=10%$, $N=90%$
     • PNet$_{F20}$: $M=20%$, $N=80%$

We have made the training and test sets available for download via the following links:

• Google Drive
• BaiDu Drive (Passwd: he37)

Once downloaded, place data.zip in the code/data directory and unzip it.

python code/TrainANet/TrainDDP.py --gpu_id 0 --ration 1 
# ration represents the proportion of pixel-level labels
# we find that one card training is better than four or eight cards

python code/TrainANet/Test.py --ration 1 
# ration represents the proportion of pixel-level labels

python code/TrainANet/TrainDDP.py --gpu_id 0 --ration 1 --q_epoch 20 --batchsize_fully 6 --batchsize_weakly 24 
# ration represents the proportion of pixel-level labels
# q_epoch means we change the q to 1 at this epoch 
# batchsize_fully means the number of fully annotated samples in a batch
# batchsize_weakly means the number of weakly annotated samples in a batch

python code/TrainPNet/Test.py --ration 1 
# ration represents the proportion of pixel-level labels

For ANet

We release the weight and prediction maps of $N=99%$, $N=95%$, $N=90%$ and $N=20%$ at Biadu Link.

For PNet
