METHOD AND APPARATUS FOR CODING MODE DECISION

摘要

Disclosed are a method and an apparatus for determining a coding mode. The method for determining a code mode includes the steps of: predicting a value of a distortion and an amount of bits generated when being coded in a current coding block (CB) in a candidate coding mode to estimate a rate-distortion (RD) cost; comparing the minimum RD cost produced based on the current CB with the estimated RD cost to determine whether a coding operation with respect to the candidate coding mode is omitted; and determining a final coding mode of the current coding block based on the minimum RD cost.
