本文介绍了一种基于MATLAB的数字图像处理应用系统，该系统提供了图像旋转缩放等功能。通过MATLAB工具，用户可以轻松地对图像进行处理，包括加载图像、查看图像信息等操作。

1 简介

数字图像处理技术(Digital Image Processing)指的是所输入的图像被转换为一种数字信号形式,并且利用计算机对其进行相应处理的技术.目前,数字图像处理技术广泛应用于农业生产过程,医学诊断,科学研究,航空航天领域以及军事制导等领域.该技术能够对图像进行大量快速的处理,再现性好,处理精度高,具有很高的适用范围. 为方便用户更好地使用数字图像处理技术,本文应用MATLAB工具开发的数字图像处理应用系统,可为用户提供数字图像旋转缩放功能。
