Abstract

Palmprint has gained popularity as a biometric modality and has recently attracted significant research interest. The competition-based method is the prevailing approach for hand-crafted palmprint recognition, thanks to its powerful discriminative ability to identify distinctive features. However, the competition mechanism possesses vast untapped advantages that have yet to be fully explored. In this paper, we reformulate the traditional competition mechanism and propose a Comprehensive Competition Network (CCNet). The traditional competition mechanism focuses solely on selecting the winner of different channels without considering the spatial information of the features. Our approach considers the spatial competition relationships between features while utilizing channel competition features to extract a more comprehensive set of competitive features. Moreover, existing methods for palmprint recognition typically focus on first-order texture features without utilizing the higher-order texture feature information. Our approach integrates the competition process with multi-order texture features to overcome this limitation. CCNet incorporates spatial and channel competition mechanisms into multi-order texture features to enhance recognition accuracy, enabling it to capture and utilize palmprint information in an end-to-end manner efficiently. Extensive experimental results have shown that CCNet can achieve remarkable performance on four public datasets, showing that CCNet is a promising approach for palmprint recognition that can achieve state-of-the-art performance.

Requirements

If you have already tried our previous work CO3Net, you can skip this step.

Our codes were implemented by PyTorch 1.10 and 11.3 CUDA version. If you wanna try our method, please first install necessary packages as follows:

pip install requirements.txt

Data Preprocessing

To help readers to reproduce our method, we also release our training and testing lists (including PolyU, Tongji, IITD, Multi-Spectrum datasets). If you wanna try our method in other datasets, you need to generate training and testing texts as follows:

python ./data/genText.py

Pretrained Model

To help readers use our model, we release our pretrained models for Tongji and IITD. Because this method is designed under a close-set setting, we encourage the readers to train our method in your dataset.

Training

After you prepare the training and testing texts, then you can directly run our training code as follows:

python train.py --id_num xxxx --train_set_file xxxx --test_set_file xxxx --des_path xxxx --path_rst xxxx

• batch_size: the size of batch to be used for local training. (default: 1024)
• epoch_num: the number of total training epoches. (default: 3000)
• temp: the value of the tempture in our contrastive loss. (default: 0.07)
• weight1: the weight of cross-entropy loss. (default: 0.8)
• weight2: the weight of contrastive loss. (default: 0.2)
• com_weight: the weight of the traditional competition mechanism. (default: 0.8)
