matlab 去雾gui设计

以下是一个基本的 MATLAB 去雾 GUI 设计的示例：

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

该 GUI 包含以下组件：

1. 一个 `axes` 对象，用于显示加载的图像。
2. 一个 "Load Image" 按钮，用于加载图像文件。
3. 一个 "Remove Haze" 按钮，用于从加载的图像中去除雾气。
4. 一个 "Gamma Correction" 滑块和一个相关的编辑框，用于控制去雾算法中的 gamma 矫正参数。
5. 一个 "Reset" 按钮，用于将 gamma 矫正参数重置为默认值。

在此 GUI 中，"Load Image" 按钮和 "Remove Haze" 按钮都与回调函数 `load_btn_Callback` 和 `remove_haze_btn_Callback` 相关联。当用户单击 "Load Image" 按钮时，回调函数将弹出一个文件对话框，允许用户选择一个图像文件。当用户单击 "Remove Haze" 按钮时，回调函数将使用去雾算法从加载的图像中去除雾气，并将结果显示在 `axes` 对象中。

"Gamma Correction" 滑块和编辑框都与回调函数 `slider1_Callback` 和 `gamma_edit_Callback` 相关联。当用户移动滑块时，回调函数将更新编辑框的值。当用户在编辑框中输入新值时，回调函数将更新滑块的值。"Reset" 按钮与回调函数 `reset_btn_Callback` 相关联，用于将 gamma 矫正参数重置为默认值。

这只是一个简单的示例，你可以根据你的需求添加其他组件和回调函数。
