Description: 本论文主要介绍图像处理系统软件的算法分析、代码实现。以及实现软件开发的程序开发工具Delphi的简单介绍。软件开发的目的是实现对图像的锐化、扭曲、波浪平滑处理等效果。文章的主要内容为该软件的算法分析过程、代码编写、界面设计和系统实现过程。本论文特别对图象的锐化、图象的扭曲和图象的平滑处理算法进行了系统的分析和比较，如锐化功能的差分法与边缘提取算法的分析、比较，平滑功能的平滑滤波法、中值滤波法、自适应滤波法等算法的分析、比较。然后对确定的这几个功能算法的实现编写了Delphi的算法代码，其中心代码在文中将详细介绍。论文最后介绍了本软件的界面设计过程和界面设计结果，并对其中几个主要按钮的代码实现做了介绍。是介绍整个软件开发过程的文章。- This paper mainly introduces the arithmetic analyze and code realization of system software for image processing. It also briefly introduces Delphi, a program exploitation tool that realizes the software exploitation. Software exploitation aims to realize the sharpening and twisting of images as well as the smoothing of waves. The main content of this paper is the process of arithmetic analyze, the compiling of codes, the designing of interface and realization of system for this software.This paper special to Analysis and compare the arithmetic of image sharpening、image twisting、image smoothing. For example，the analyze and comparison of the bad cent method arithmetic and the edge withdraws arithmetic about sharpening function. the analyze and comparison of the smooth wave method、The inside is worth wave method、Nature orientation wave method. Then to plait writes the Delphi Calculate way code to realize the certain of function calculate. The heart code will detailed introduce at the pa Platform: |

Description: 思路简要说明：
1、图像二值化
将图片中的各点用0或1表示，1为有效点，0为背景。这里使用的是最大类间方差法
（otsu），在资料中有介绍。
2、去除干扰点
3、分割
将整个的图片分为每个单独的字，在下一步中才能一一识别。
4、与样本库进行对比，寻求最近似匹配
这步是比较核心的地方，由于要识别的图形每次都是随机变化的，我们不能进行完
全匹配识别，所以使用的是‘欧氏距离’来进行最近似匹配，资料中的《自由手写体
数字识别》里面有详细说明。
（样本库文件是按照匹配的特征通过事先编写的程序进行学习得到的）
该识别思路对目前很多验证码有效，识别速度快，正确率基本还可以（在一定程度内
样本量越大正确率越高），不能识别的情况也不少，比如字符粘连，导致程序无法正确
分割，从而识别失败，有朋友介绍神经网络识别方法不错，有空一定要学习下。-A brief description of ideas:
1, image binarization
Pictures of all the points expressed by 0 or 1, 1 for the effective point, 0 for background. Used here is the largest between-class variance
(Otsu), are introduced in the data.
2, removal of interference points
3, partition
The whole picture is divided into each individual character, in the next step in order to identify 11.
4, compared with the sample database, the search might match the recent
This step is to compare the core places, due to the recognition of each of the graphics changes are random, we can not be finished
Identification of the entire match, so the use of the Euclidean distance to be like the recent match, the information in the "free handwritten
Digital Identification, "which is described in detail.
(Sample library features in accordance with the matching pre-prepared through the process of learning to be)
The identification of a lot of ide Platform: |
