Image processing method in which noise is signal dependent

摘要

Procedure for treatment of a pixel type image based on statistical treatment of the acquired data. Procedure involves acquiring (100) a pixel image (JO), in which the intensity has both signal and signal dependent noise components (101); removing the intensity bands (QMk) from the uniform image (Mk) (111) and determining statistical laws (f) between noise variation (Hk) at levels (QSk) and noise levels in the intensity bands (QMk) (114). Statistical laws are used to determine several noise levels (SBk) as a function of the uniform intensity (Mk) of the image (120), with the noise curve (NC) as a statistical law (g) between the change in the noise (SBk) with intensity (Mk) of the image. An Independent claim is made for a medical imaging device making use of the statistical process.
