2DWaveletsimpression
- 由于小波及小波包技术可以将信号或图像分层次按小波基展开,所以可以根据图像信号的性质以及事先给定的图像处理要求确定到底要展开到哪一级为止,从而不仅能有效地控制计算量,满足实时处理的需要,而且可以方便地实现通常由子频带、层次编码技术实现的累进传输编码(即采取逐步浮现的方式传送多媒体图像)。这样一种工作方式在多媒体数据浏览、医学图片远程诊断时是非常必要的。另外,利用小波变换具有放大、缩小和平移的数学显微镜的功能,可以方便地产生各种分辨率的图像,从而适应于不同分辨率的图像I/O设备和不同传输速率的通信系

- 二维图像信号的去噪步骤: (1)二维图像信号的小波分解。选择合适的小波与恰当的分解层次N,并对待压缩的二维图像信号进行N层分解计算。 (2)对分解后的每一层高频系数,选择一个恰当的阈值,并对该层高频系数进行软阈值量化处理。 (3)二维图像信号的小波重构。用小波分解后的第N层近似(低频系数)和经过阈值量化处理后的各层细节(高频系数),对二维信号进行小波重构。-Two-dimensional image signal denoising steps: (1) two-dimensiona
