说明：  对图像目标识别和提取，主要通过改进非线性阈值分割实现(For image target recognition and extraction, the main method is to improve the non-linear threshold segmentation.)

彩色图像纹理提取的一种算法，效果还挺好的(color image of a texture extraction algorithm, It's a good result)

用图像分割的方法提取树叶病斑坏死区域并显示(Necrotic lesion leaves the region extraction method, and displays the image segmentation)

基于DCT,DFT,DWT等的水印算法，还有加置乱的水印算法，用于图像处理方面(Based on the DCT, DFT, DWT, such as the watermarking algorithm, as well as increase the watermark scrambling algorithm, for image processing)

本人用matlab自己做的图像分裂合并程序，主要对印章图像进行处理．(own image split the merger process, mainly to seal image processing.)

卡尔曼滤波是一种数据处理方法，它是一种线性最小方差无偏估计准则，基于系统 状态估计和当前观测，通过引入状态空间而获得的新的状态估计.本篇论文陈述了卡尔曼滤 波的基本思路和算法；并通过仿真，显示卡尔曼滤波的功能，以及如何用它来跟踪方向确定、速度恒定的飞行器。 (Kalman filter is a data processing method, which is a linear minimum variance unbiased estimation criteria, based on system state estimation and the current observations, obtained by introducing the state space of the new state estimate of the Kalman filter thesis statement the basic ideas and algorithms and through simulation, shows Kalman filtering functions, and how to use it to keep track of the direction determined constant speed aircraft.)

输入图片的一阶矩、二阶矩、三阶矩。颜色空间可以在计算前更改( the first moment, second moment and third moment of the picture)

说明：  计算机图形学基本算法 DDA直线 中点直线 BRESEMHAM圆 正负法圆 B样条曲线 B曲线 (DDA line algorithm for computer graphics, the midpoint of the basic straight-line method BRESEMHAM circle round the positive and negative B-spline curve B curve)

matlab做的图像去噪程序，使用的是维纳滤波法（winner），内附图像，可直接运行(matlab image denoising procedure, using the Wiener filter method (winner), included images, can be run directly)

FPGA数字图像处理实现均值滤波，并且仿真将生成图片写出TXT格式以便使用MATLAB查看(Mean filter is realized by digital image processing in FPGA, and the generated image is written in TXT format for viewing with MATLAB.)
