说明：  用Matlab读取RAW格式（单反相机）图片，然后进行插值处理并存为JPG格式图片。(Read RAW format using Matlab (SLR) picture, and then interpolated coexist as a JPG format picture.)

数字图像处理的入门介绍和一些函数、原理的使用，比较适合初学者使用(Introduction to digital image processing and some of the functions, the use of the principle, more suitable for beginners)

说明：  经典图像处理灰度图像去噪模型，以及改进模型效果不错(Classic image processing gray image denoising model, and improved model good results.)

Itti模型的显著图提取，使用matlab编写，很好的代码，可供参考学习(Itti model saliency map extraction, the use of matlab prepared very well the code)

MATLAB工具sift实现图像拼接，上下拼接(MATLAB tool sift image stitching, stitching up and down)

Retinex理论的基础理论是物体的颜色是由物体对长波（红色）、中波（绿色）、短波（蓝色）光线的反射能力来决定的，而不是由反射光强度的绝对值来决定的，物体的色彩不受光照非均匀性的影响，具有一致性，即retinex是以色感一致性（颜色恒常性）为基础的。不同于传统的线性、非线性的只能增强图像某一类特征的方法，Retinex可以在动态范围压缩、边缘增强和颜色恒常三个方面打到平衡，因此可以对各种不同类型的图像进行自适应的增强。(The basic theory of Retinex theory is the color of the object by object for the long wavelength (red), medium (green), short wave (blue) light reflection ability to decide, rather than by the intensity of reflected light of the absolute value to decide, the color of the object under illumination nonuniformity effects, consistent with the Retinex, that is based on color constancy (color constancy based). Different from the traditional linear, nonlinear image enhancement method of only one kind of features, Retinex can be in dynamic range compression, edge enhancement and three aspects of color constancy hit the balance, thus enhancing adaptive to a variety of different types of images can be.)

利用多用方法进行数字图像去模糊实例，便于初学者理解反卷积去模糊、伪逆去模糊等基本算法(Example scripts for image debluring, try to give general introduction of some basic algorithms, such as pseudo inverse debluring.)

MRF代码实现,visual C++ 代码，不错，可以尝试(an implementation of MRF)

说明：  用matlab将图片转成灰度图TXT，再通过verilog将数据导入FPGA中，采用高斯滤波算法来处理，再将处理后的图片数据导出到TXT中。(The image is transformed into gray-scale image TXT by MATLAB, and then the data is imported into FPGA by Verilog, processed by Gauss filter algorithm, and then the processed image data is exported to TXT.)

多聚焦图像融合的源代码，还包括几个评价指标的的function函数(Multi-focus image fusion source code, also includes several evaluation function function)
