摘要： Provided are a method and apparatus for encoding and decoding in an intra mode based on a multiple scanning method through which efficiency of the intra mode is improved by using a spatial relationship within a frame more and obtaining estimation information from numerous references. The method includes: dividing an input image into basic encoding units composed of predetermined sized blocks; scanning at least one of the basic encoding units; determining whether references for motion estimation of a current basic encoding unit can be used as references to encode the current basic encoding unit; and encoding the current basic encoding unit according to a result of the determination.

摘要： A deblocking method and apparatus using an edge flow-directed filter and curvelet transform for deblocking Block Discrete Cosine Transform (BDCT) compressed images. The deblocking method includes: extracting an edge flow vector from a Block Discrete Cosine Transform (BDCT) compressed image to identify a direction of changes in image attributes; performing a dyadic discrete wavelet transform on the BDCT compressed image; selectively filtering a highpass wavelet image among dyadic discrete wavelet transform compressed images according to an edge flow direction of an edge pixel; performing a curvelet transform on an image including the selectively filtered highpass wavelet image and wavelet images other than the highpass wavelet image; and estimating an original image before being BDCT compressed using the curvelet transform.

摘要： Provided are a method and apparatus for encoding and decoding in an inter mode based on a multiple scanning through which efficiency of the inter mode is improved by using a spatial relationship within a frame and obtaining estimation information from numerous references. The method includes dividing an input image into basic encoding/decoding units including predetermined sized blocks, scanning at least one of the basic encoding/decoding units, determining whether references for motion estimation of a current basic encoding/decoding unit can be used as references to encode/decode the current basic encoding/decoding unit, and selectively encoding/decoding the current basic encoding/decoding unit according to a result of the determination. A decoded previous frame or blocks decoded before the final scan of a current frame is used the references for motion estimation.
