图像修复基于约束最小二乘方滤波实现图像复原matlab源码GUI

Posted 2021-05-26 Matlab咨询QQ1575304183

一、简介

约束最小二乘方滤波（Constrained Least Squares Filtering，aka Tikhonov filtration,Tikhonov regularization）核心是H对噪声的敏感性问题。减少噪声敏感新问题的一种方法是以平滑度量的最佳复原为基础的，因此我们可以建立下列约束条件：

二、源代码

function varargout = zuixiaoercheng(varargin)
% ZUIXIAOERCHENG M-file for zuixiaoercheng.fig
%      ZUIXIAOERCHENG, by itself, creates a new ZUIXIAOERCHENG or raises the existing
%      singleton*.
%
%      H = ZUIXIAOERCHENG returns the handle to a new ZUIXIAOERCHENG or the handle to
%      the existing singleton*.
%
%      ZUIXIAOERCHENG('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in ZUIXIAOERCHENG.M with the given input arguments.
%
%      ZUIXIAOERCHENG('Property','Value',...) creates a new ZUIXIAOERCHENG or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before zuixiaoercheng_OpeningFunction gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to zuixiaoercheng_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
