Webthe psycho-visual redundancy of display devices can be used to generatemultiple visual percepts for diﬀerentviewers, with and without viewing devices. Second, the redundancy can be used for data transmission to computing devices without sacriﬁcing the visual quality, which is in fact a kind of visible light com-munication (VLC). WebPsycho-visual Redundancy 2.1 CODING REDUNDANCY A code is a system of symbols used for information representation. The pieces of information are represented by a combination of symbols called a codeword, and their length is called the number of symbols in a codeword. The available grey levels in an image are assigned to various codewords. harry potter fanclub konto
