英文摘要： Deep learning is a kind of cognitive learning to simulate the human visual perception of the nervous system, hierarchical and incremental deep learning can get more high-level features, and it is suitable to the field of multimodal biometrics recognition. According to the low efficiency drawbacks of the traditional deep learning models, based on the preliminary studies, the project intends to do the researches on building a deep learning model and recognition for multimodal biometrics image with extreme learning units. The studies include : ① The image pre-processing and data fusion of the multimodl biometrics images; ② Fusing the extreme learning into deep learning to build the deep learning units , and combining the variational Bayesian inference, Adaptive Fuzzy Particle Swarm Optimization (AF-PSO), sparse structure optimization algorithms to improve the learning efficiency; ③Based on the built extreme learning machine units, we determine the network parameters of the learning unit of each layer to performe the hierarchical, incremental learning on the deep learning networks;Besides, it is able to fuse the certain learning methods according to the different input environments. ④Using the learned high-level representation features for multimodal biometrics recognition. By studying the above contents, we will build a new and effective deep learning model, and hope to provide new ideas and methods for the multimodal biometrics authentication, and also lay the foundation for further study.
