边缘检测算法的一种实现

按照指定分隔符将已知字符串分割成个部分，并以cell存储(In accordance with the specified separator known string divided into parts, and cell storage)

四边形网格扫描转化与交互式编辑 实现四边形网格交互式编辑：要求实现四边形扫描转化算法，以此为基础，实现四边形网格中所有四边形的扫描转化、颜色添充；并通过交互改变四边形顶点位置体会交互式图形系统特点。(Quadrilateral mesh scan conversion and interactive editing Quadrilateral grid interactive editing: Quadrilateral scan conversion algorithms required to achieve, on this basis, to achieve all quadrilateral quadrilateral scan conversion, color Tim charge and changing the quadrilateral vertex position by exchanging experience the interactive features of the graphics system.)

求灰度图像的梯度特征向量，以便用于目标检测(The grad feature of gray image can be achieved by the code.)

Harris，SURF特征点提取匹配算法，两种算法实例比较(Harris, SURF feature point extraction matching algorithm compares two algorithms examples)

说明：  该文件主要用于减少相干斑噪声，包含各种常见的滤波器如Lee滤波器，Frost滤波器等(This file is mainly used to reduce speckle noise, including a variety of common filters, such as Lee filter, frost filter and so on)

基于亚像素运动估计算法的块匹配运动，有源码跟参考文献，初学的小伙伴可以看看(Block-matching motion estimation algorithm based sub-pixel motion, there is source code with references, beginner can look at a small partner)

raw 数据转换成plant 的yuv 数据，已经测试通过。希望对raw数据进一步处理的同学有帮助。( Raw data is converted into YUV plant data, has been tested through. Hope that the raw data to further deal with the students to help. )

使用matlab实现的,基础单变量以及多变量梯度下降算法,和信号分类以及信号归一化部分算法，是机器学习领域最基本的代码，希望大家多多交流(matlab implementation of basic univariate and multivariate gradient descent and signal classification algorithms, machine learning basic code, hope that more exchanges)

说明：  相机是将三维世界坐标系中的坐标点映射到二维图像平面的过程能够用一个几何过程描述，最简单模型称为针孔模型。 因为相机镜头透镜的存在，使得光线投影到成像平面过程中产生了畸变。(Camera is the process of mapping coordinate points in three-dimensional world coordinate system to two-dimensional image plane, which can be described by a geometric process. The simplest model is called pinhole model. Because of the existence of camera lens, the light rays are distorted when they are projected onto the image plane.)

最邻近插值的matlab实现代码，可以对图像进行插值，插值的方法为最邻近插值法(The nearest neighbor interpolation matlab code, image interpolation, interpolation methods nearest neighbor interpolation)
