【图像检测】基于gabor滤波实现布匹瑕疵检测matlab代码

1 简介

给出一种基于多通道Gabor滤波技术实现高速实时布匹瑕疵检测方法.在多分辨率和多方向上分别对图像进行Gabor滤波,建立金字塔图像表示结构,并对滤波后的多幅图像进行融合与重建,把瑕疵区域从布匹背景中提取出来,从而实现对布匹瑕疵的实时检测.实验表明,这种方法的检测准确率可达到95%,而且具有计算量小、稳定性好等优点.

2 部分代码

function varargout = bupi(varargin)

% BUPI MATLAB code for bupi.fig

%     BUPI, by itself, creates a new BUPI or raises the existing

%     singleton*.

%

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

%     the existing singleton*.

%

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

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

%

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

%     existing singleton*. Starting from the left, property value pairs are

%     applied to the GUI before bupi_OpeningFcn gets called. An

%     unrecognized property name or invalid value makes property application

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

%

%     *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one

%     instance to run (singleton)".
