说明：  matlab应用于神经网络：利用BP算法及Sigmoid函数，研究函数的逼近问题。(matlab applied to neural networks: the use of BP algorithm and Sigmoid function is to study the function approximation problem.)

：针对TV模型修复算法只沿梯度垂直方向扩散，容易在平滑区域引入阶梯效应，迭代效率低，易产生假边缘的缺点，分析比较了TV图像修复模型的性能，提出了一种改进的图像修复算法。(Abstract：TV image inpainting only repairs algorithm along the vertical direction，making diffusion gradi— ent in smooth area into stair step effect，reducing iterative efficiency，producing false edge faults．We ana— lyse and compare the TV image restoration model and repair the performance of the model is put forward in this paper．Puts forward an improved image restoration algorithm)

基于小波分析和主成分分析的人脸识别研究随着社会的发展，社会各个方面对快速有效的身份验证的要求日益迫切。由 于生物特征是人的内在属性，具有很强的自身稳定性和个体差异性，因此是身份 验证的理想依据。其中利用人脸特征又是最自然直接的手段，相比其他生物特征， 它具有直接、友好、方便的特点，易于为用户接受。从而，人脸识别吸引了越来 越多来自计算机视觉和信号处理等领域的关注，成为模式识别、图像处理等学科 的研究热点。(Based on wavelet analysis and principal component analysis of the Face Recognition With the social development of all aspects of society in his capacity as quickly and efficiently verify the requirements of increasingly urgent. Biological characteristics as a result of the inherent human attribute, has a strong individual differences in their stability and, therefore, is an ideal basis for authentication. The use of facial features which is the most natural means of direct, compared with other biological characteristics, it has a direct, friendly, convenient and easy for users to accept. Thus, face recognition has attracted more and more from the computer vision and signal processing and other areas of concern, as a pattern recognition, image processing, such as the research subjects.)
