Fading: Selective fading causes a cloudy pattern to appear on an FFT display. Fading refers to the distortion that a carrier-modulated telecommunication signal experiences over certain propagation media. A fading channel is a communication channel that experiences fading. In wireless systems, fading is due to multipath propagation and is sometimes referred to as multipath induced fading. This is about the phenomenon of loss of signal in telecommunications.
Erosion: Erosion is one of two fundamental operations in Morphological image processing from which all other morphological operations are based. The operation is a subset of set theory, where each pixel in an image is considered to be a member of a set of pixel, rather that the usual interpretation of an image being a strict function of two dimensions.
fading = reduction in amplitude(hence reduction in range of values)
eroding = dunno exact definition. but its diminishing all the brighter points(so the darker portion seems to increase in area).
why dont u google out for better material
