课程设计 基于matlab的工件图像尺寸测量技术(The course design is based on matlab the workpiece image size measurement techniques)

采用考虑湍流内外尺度影响的退化模型来恢复大气湍流降质图像，运用包含了湍流内外尺度影响的波结构函数、折射率谱以及薄透镜成像的退化函数导出了新的退化模型。(A new degradation model includling the influence of outer-and inner-scale of turbulence is presented to restore atmospheric turbulence degradation images. )

说明：  一个纹理坐标自动生成的例子，有助于理解纹理坐标自动生成的各个函数(An example of automatically generated texture coordinates, texture coordinates generated automatically help you understand the various functions)

说明：  二进小波变换的图像增强,matlab代码(Dyadic wavelet transform image enhancement, matlab code)

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.)

图片去噪：对一幅图像加入不同的噪声（随机点噪声、椒盐噪声等），选取不同的方法去噪，比如说邻域平均、中值滤波、图像迭加等，比较对于不同的噪声，不同的方法哪种更好(Image denoising: for an image by adding different noise (random-dot noise, salt and pepper noise, etc.), select a different method of denoising, for example, the neighborhood average, median filter, image superposition and so on, compared for different noise, different methods which better)
