A Brief Introduction to SEM (Scanning Electron Microscopy)

Image noise is random variation of brightness or color information in images, and is usually an aspect of electronic noise. It can be produced by the image sensor and circuitry of a scanner or digital camera. Image noise can also originate in film grain and in the unavoidable shot noise of an ideal photon detector. Image noise is an undesirable by-product of image capture that obscures the desired … WebAuditory dominance refers to the auditory information in multisensory integration; more priority is given to auditory information, and it is processed in a dominant position.
