说明：  基于MATLAB的条形码识别。带GUI可视化用户操作界面。读取条形码，经过一系列预处理，如灰度化，去噪，直方图增强，中值滤波，二值化，腐蚀，识别等。可识别20多张条形码图片，另外可定制二维码的识别，二维码可自定义生成内容，生成二维码，然后嵌入数字水印进行加密传输，接收方提取水印的二维码，识别。(Bar code recognition based on MATLAB. Visual user interface with GUI. Read bar code, after a series of preprocessing, such as graying, denoising, histogram enhancement, median filtering, binarization, corrosion, recognition and so on. It can identify more than 20 bar code images, and can customize the identification of two-dimensional code. The two-dimensional code can generate the content of the two-dimensional code, generate the two-dimensional code, and then embed the digital watermark for encryption transmission. The receiver can extract the two-dimensional code of the watermark for identification.)

用C写的图像融合代码，包括了医学图像融合、多焦点图像融合和多传感器图像融和等多种类型的融和算法，运行速度快。(Image fusion with the C written code, including the medical image fusion, multi-focus image fusion and multi-sensor image fusion and many other types of fusion algorithms, to run fast.)

图像降噪、贝叶斯估计、盲源降噪,采用盲源方法进行噪声估计，再进行贝叶斯非局部均值降噪(Image denoising, Bias estimation and blind source noise，The blind source method for noise estimation, then the Bayes non local mean noise reduction)

语音特征提取代码，提取mfcc和lpcc。(Speech feature extraction code, and extract mfcc lpcc.)

说明：  机器视觉系统实例--颜色识别系统，matlab实现(Examples of machine vision systems- the color identification system, matlab achieve)

飞机的设计和制造一直是与性能优异的材料 联系在一起。20世纪60年代中期以碳纤维为增强体 的复合材料问世，70年代初开始应用于军用飞机 结构，80年代开始应用于民用飞机结构。复合材料 具有比强度高和比刚度高的独特优点，飞机结构 采用复合材料，其重量可相应减少20%~30%[1]。此 外，复合材料还具有可设计性强、疲劳性能好、耐 腐蚀、易于大面积整体成型、维护性好等优点。目 前，复合材料已经成为重要的飞机结构材料。(he design and manufacture of aircraft has been a material with excellent performance Relate. In the mid 1960s, carbon fibers were used as reinforcements The composite material came out and was used in military aircraft in the early 70s The structure began to be applied to civil aircraft structures in 80s. Compound material The aircraft structure has the unique advantages of high specific strength and high specific stiffness The weight of the composites can be reduced by 20%~30%[1] accordingly. this Besides, the composite material has the advantages of good design, good fatigue performance and good resistance to fatigue Corrosion, easy to form a large area, good maintainability and so on. order Before, composite materials have become important aircraft structural materials.)
