基于matlab的图像形状与分类 - 毕业设计(7)

附录

致 谢

在论文完成之际，我心情无法平静。大学期间，尤其是毕业论文完成期间，有很多可敬的老师和同学给予了我无私帮助。对此我深怀感激。

首先感谢导师方旺盛老师从始至终的关心、指导和教诲。方旺盛老师追求真理、一丝不苟、严格律己、宽以待人的崇高品质对学生将是永远的鞭策。

本次毕业设计从课题选题、信息收集到论文的撰写都是在方旺盛老师全面、具体、耐心的指导下进行的。特别是方旺盛老师不厌其烦的指出设计中的不足及问题的解决方向，使我感受到方旺盛老师的渊博学识、敏锐思维和民主严谨的作风。论文写作过程中，从行文的用语到格式的规范，都力求完美。这里再次对方旺盛老师的无私付出表示深深的谢意。

其次在设计的过程中，感谢给予我帮助的同学们，在此对其表示感谢。 然后感谢信息工程系各位老师对我的培养和关心，感谢我的家人在大学期间对我的支持和鼓励。

论文中所用程序：

边缘提取及形状识别分类的主程序

function varargout = chuongtrinhnhandang(varargin)

% CHUONGTRINHNHANDANG M-file for chuongtrinhnhandang.fig % CHUONGTRINHNHANDANG, by itself, creates a new CHUONGTRINHNHANDANG or raises the existing

% singleton*. %

% H = CHUONGTRINHNHANDANG returns the handle to a new CHUONGTRINHNHANDANG or the handle to

% the existing singleton*. %

%

CHUONGTRINHNHANDANG('CALLBACK',hObject,eventData,handles,...) calls the local

% function named CALLBACK in CHUONGTRINHNHANDANG.M with the given input arguments.

%

% CHUONGTRINHNHANDANG('Property','Value',...) creates a new CHUONGTRINHNHANDANG or raises the

% existing singleton*. Starting from the left, property value pairs are % applied to the GUI before chuongtrinhnhandang_OpeningFunction gets called. An

% unrecognized property name or invalid value makes property application

% stop. All inputs are passed to chuongtrinhnhandang_OpeningFcn via varargin.
