摘要： Disclosed is a high-resolution video encoding/decoding method and apparatus. The video encoding method includes: predicting a current block to generate a predicted block, subtracting the predicted block from the current block to generate a residual block, determining a transform and quantization type according to the block type of the current block; transforming and quantizing the residual block according to the determined transform and quantization type; and encoding the transformed and quantized residual block. According to the video encoding/decoding method and apparatus, not only the encoding efficiency can be improved because it enables an encoding using a high correlation between temporally/spatially adjacent pixels appearing in a video, but the compression efficiency can also be improved by reducing block distortion.

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.
