METHOD AND DEVICE FOR ENCODING/DECODING IMAGE IN SPATIAL DOMAIN FOR NOISE COMPONENT

摘要

An embodiment of the present invention relates to a method and a device for encoding/decoding an image in a spatial domain for noise components, which is a method and a device for encoding/decoding an image in which: a current block is predicted such that a prediction block is generated, and then said prediction block is deducted from said current block to generate a residual block; it is determined whether or not there are as many noise components of said residual block as the number of a preset range; an encoding domain is determined; if the determined encoding domain is a frequency domain the residual block is transformed and quantized; if the determined encoding domain is a spatial domain information on the encoding domain, which was determined by quantizing said residual block, and a generated quantized block are encoded or said noise components are quantized; and the quantized noise components and information on the number of said noise components and the location of said noise components are encoded and decoded.
