Data that represent complex and multivariate processes are well known to be multiscale due
to the variety of changes that could occur in a process with different localizations in time and …

摘要小波图象去噪已经成为目前图象去噪的主要方法之一. 在对目前小波去噪文献进行理解和
综合的基础上, 首先通过对小波去噪问题的描述, 揭示了小波去噪的数学背景和滤波特性; …

Apparent streak-like artifacts will present in reconstructed images due to excessive quantum
noise in low-dose X-ray imaging process. Dealing with the noisy sinogram before a filtered …

This paper presents a new spatially adaptive wavelet denoising method. Based on a doubly
stochastic process model of wavelet coefficients, the method gives a new threshold, which …

Early detection of small hepatocellular carcinoma (SHCC) has very important clinic value,
and wavelet denoising arithmetic research of SHCC CT image, based on image processing …

Many real word images are often contaminated by noise. Noise reduction techniques aim to
improve image quality and can be used to facilitate further image processing. This work …
