资源介绍:

数字图像处理是指利用计算机科学和数字信号处理的技术来改进和增强图像的质量、改变图像的外观、提取图像的特征以及实现图像分析和理解的过程。数字图像处理可以包括图像增强、图像复原、图像压缩、图像分割、图像识别等多个方面。在数字图像处理中，常用的技术包括滤波、边缘检测、图像配准、图像重建、图像融合等。滤波可以通过去噪、增强细节等方式改善图像的质量。边缘检测可以找出图像中物体的边界。图像配准可以将多幅图像对齐，用于图像拼接或者图像叠加。图像重建可以根据有损压缩后的图像进行恢复，以提高图像质量。图像融合可以将多个图像的信息融合成一个图像，用于提高图像的观看效果。数字图像处理在许多领域中都有广泛的应用，包括医学图像处理、遥感图像处理、安全监控、计算机视觉等。医学图像处理可以用于诊断和治疗，例如通过图像分割和特征提取来辅助疾病检测。遥感图像处理可以用于地理信息系统和环境监测，例如通过图像分类和变化检测来分析土地利用和覆盖变化。安全监控可以通过图像识别和分析来实现人脸识别和行为分析。计算机视觉可以用于机器人导航、自动驾驶等领域。总的来说，数字图像处理是一门利用计算机和数字信号处理技术来处理和

function varargout = GUI(varargin) % GUI MATLAB code for GUI.fig % GUI, by itself, creates a new GUI or raises the existing % singleton*. % % H = GUI returns the handle to a new GUI or the handle to % the existing singleton*. % % GUI('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in GUI.M with the given input arguments. % % GUI('Property','Value',...) creates a new GUI or raises the % existing singleton*.
