Noise reduction in digital radiography by wavelet packet using nonlinear correlation threshold

Autor: Jianming Lu, Takashi Yahagi, Shin'ya Yoshino, Takahide Okamoto, Shigeru Furui, Hiroshi Ichiji

Publikováno v: Medical Imaging: Image Processing

The influence of quantum mottle appears as degradation of graininess with reduction of the amount of incidence X-rays. The results of a Wiener spectrum study showed that graininess increased as the dose was reduced, and noise affected all frequencies
