    摘要: The present disclosure provides a method and apparatus for intra prediction encoding/decoding. The method includes: selecting an intra prediction mode of each block to be encoded; encoding a residual block generated through an intra prediction of the block according to the selected intra prediction mode to generate a coefficient bit; encoding a mode identifier for indicating the intra prediction mode according to the predetermined mode determination method to generate a mode bit; generating a bitstream including a mode bit field including a mode bit for one or more blocks and a coefficient bit field including a coefficient bit for the block; and including a mode bit field pointer for identifying the mode bit field in the bitstream. The present disclosure simplifies the process of selecting a prediction mode in a video compression to improve a compression speed and decreases a size of compressed data to improve the compression efficiency.

    摘要: The present disclosure relates to an inter prediction method and apparatus using adjacent pixels, and a video encoding method and apparatus using the same. The inter prediction method for a predictive encoding includes: determining a current motion vector by estimating a motion of a current block; generating a reference block indicated by the current motion vector; calculating a motion compensation coefficient or an average compensation coefficient by using pixels neighboring the current block and pixels neighboring reference block; generating a changed reference block reflecting the motion compensation coefficient or the average compensation coefficient in the reference block; and determining the changed reference block as a predicted block of the current block. The present disclosure reduces a difference between an actual block and a predicted block by more accurately predicting the block to be encoded, thereby improving the compression efficiency.
