Abstract
An apparatus and method for coding and decoding an image are provided. The apparatus for coding the image includes a spatio-temporal information prediction/compensation unit, a recovered image processor, a residue generator, a quantizer, and an entropy encoder. The spatio-temporal information prediction/compensation unit generates a predicted image by predicting and compensating spatio-temporal information including at least one of temporal prediction information from a current image and a recovered previous image, and spatial prediction information from a recovered current image. The recovered image processor performs a spatio-temporal noise removal process on the recovered current image using the spatio-temporal information, and stores the resulting noise-removed image. The residue generator generates a residue image obtained by subtracting the predicted image from the input image, and the quantizer outputs quantized coefficients by quantizing the residue image. The entropy encoder generates a bit stream by entropy coding the quantized coefficients.
