数字图象半色调化常用的16阶图像法

canny检测器是很有效的边缘检测器，该函数可以实现对目标图像的边缘提取。该方法总结如下：1.图像使用带有指定标准差的高斯滤波器来平滑，以此减少噪声；2.在每一点计算局部梯度和边缘方向；3.第二步中确定的边缘点会导致梯度幅度图像中出现脊，然后追踪所有脊的顶部，并将所有不再脊顶部的像素设置为0；4.执行边缘链接-canny detector is very effective edge detector, this function can be achieved on the target image edge detection. This method is summarized as follows: 1. Image used with the specified standard deviation of the Gaussian filter to smooth out, thereby reducing the noise 2. In the calculation of each point of local gradient and edge direction 3. The second step in determining the edge points will led to the image gradient magnitude ridge appears, and then keep track of all of the top of the ridge, and ridge at the top of all the pixels are no longer set to 0 4. the implementation of the edge link

原代码下载，我对计算机图形学的编程实践，包括画直线、反走样直线、画圆、 画椭圆、画矩形、画多边形、矩形填充、多边形填充、3D变换、光照、贴图等。由于 精力有限，未对原码做任何注释。出于简化编程的考虑，许多地方指定了常数，未做 通用处理。解压缩后建立gui16目录，在其下有原代码和工程文件。在gui16下建立 release目录，其下有一可执行文件及其所须的位图及模型文件。如在release目录之 外执行程序，必须复制所需位图及模型文件。-Download the original code, I have the practice of computer graphics programming, including painting a straight line, anti-aliased line, circle, drawing an oval, rectangular painting, painting polygon, rectangle fill, polygon fill, 3D transformation, light, texture and so on. Because energy is limited, the original code did not make any comment. Simplify the programming for consideration, in many parts of specified constants, GM deal done. After the establishment of gui16 extract directory, in its code and under the original project file. Gui16 established in the release directory, which under one executable file and the necessary bitmap files and models. Such as in the release directory outside of the implementation of procedures, you must copy the necessary

一个更为复杂的2D Game实例.比之前传的复杂. Windows平台的2D Game实例2, 使用了C++和OpenGL.这个souce不但是OpenGL技术,还可以学习到两个方面的技术: part1: win32的消息循环, OpenGL的设置.画一些简单的图形. part2: 处理并且显示卡通图片.-This source focuses on 2D game development with C++ and OpenGL for Windows platform. We will not only focus on OpenGL but also talk about the designs that are commonly used in game programming with a full object oriented approach. This source include two articles: Part 1: covers the win32 message loop, the window creation and the setting-up of OpenGL. You will also learn how to draw some simple shapes. Part 2 : Covers resources handling and displaying simple animations. Contents
