【边缘检测】基于sobel、prewit、canny算法实现图像边缘检测含Matlab源码

function varargout = aaa(varargin) % AAA MATLAB code for aaa.fig % AAA, by itself, creates a new AAA or raises the existing % singleton*. % % H = AAA returns the handle to a new AAA or the handle to % the existing singleton*. % % AAA( ’CALLBACK’ ,hObject,eventData,handles,...) calls the local % function named CALLBACK in AAA.M with the given input arguments. % % AAA( ’Property’ , ’Value’ ,...) creates a new AAA or raises the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before aaa_OpeningFcn gets called. An % unrecognized property name or invalid value makes property application % stop. All inputs are passed to aaa_OpeningFcn via varargin. % % *See GUI Options on GUIDE ’s Tools menu.
