The latter term refers to the effect, since kTC noise causes pixel-to-pixel variations in the CCD signal’s reset level. The data level depends on the reset level, so random variations in the reset level would translate to random variations in the light intensity associated with each pixel. A typical value for reset noise is 50 electrons RMS.Feb 2, 2008 · Sensor noise suppression tends to reduce the dimensionality of multichannel data (inflated by sensor-specific noise sources), and thus it may be a useful preprocessing step for methods such as ICA (e.g. Barbati et al. 2004 ).
