Image-Processing-by-DWT

中文(Chinese):该程序基于MATLAB R2018b编写,具备GUI界面(基于GUIDE环境)。程序使用小波变换对图像进行处理,包括图像融合、图像降噪、图像压缩和图像隐藏。程序提供图片测试素材,可参照素材内容自行制作其他图片素材。目前程序尚不完善,有待进一步改进。感谢你的关注!兼容性:未经过严格测试,但编写时尽量使用旧函数,以尽力保证在旧版MATLAB上可以运行。

English: The program is written based on MATLAB R2018b and features a GUI interface (developed in the GUIDE environment). It utilizes wavelet transform for image processing, which includes image fusion, denoising, compression, and image hiding. The program provides sample image materials for testing, allowing users to create additional image resources based on these samples. Currently, the program is not perfect and is subject to further improvement. Thank you for your attention! Compatibility: It has not been rigorously tested, but older functions were used as much as possible during development to ensure compatibility with older versions of MATLAB.

更新日志:V1.2(2024.5.13)1. 图像处理支持彩色图片,不仅限于灰度图片(极个别功能除外);2. 图像预处理中,支持自定义高斯噪声的均值和方差;3. 在程序中可以对图像进行放大、缩小、移动和标定数据操作;4. 窗口支持放大和缩小;5. 修改和增加部分注释;6. 提升异常处理,运行期间遇到的大部分错误将会以消息框形式显示而不是出现在MATLAB命令行;未来更新计划:增加程序说明文档。V1.1(2024.4.18):1. 对计算PSNR和NC出现错误时的提示进行了改进;2. 新增图像预处理功能,可以对图像进行灰度转换和高斯加噪。未来更新计划:增加更多的异常处理机制。V1.0(2023.11.22):第一个版本。
