Abstract: An efficient image encoding method for H.264 SVC is provided. When a base layer macroblock mode MODEBL is intra, the image encoding method calculates a I16×16 mode value for a Pred_Mode of I16×16 of the MODEBL, calculates a mode value of the base layer, compares the I16×16 mode value with the mode value of the base layer, and thus selects the best mode. Also, the method calculates a mode value for a skip mode of the base layer, compares the skip mode value with a pre-determined quantization parameter threshold, and thus selects the best mode. Hence, the image coding efficiency can be enhanced by improving complexity in the mode decision in the H.264 SVC encoding process.

Abstract: In a method for image prediction of a multi-view video codec, a disparity vector value of a current macroblock is obtained and a corresponding macroblock is searched through the obtained disparity vector value. An intra prediction coding direction value of the searched macroblock is determined as an intra prediction coding direction value of the current macroblock. The current macroblock is coded/decoded through the determined intra prediction coding direction value. The coding efficiency can be increased by reducing a coding amount by omitting a process of obtaining an unnecessary disparity value by using a different-view intra prediction coding direction as a current-view intra prediction coding direction. The coding efficiency can be increased by reducing a coding amount by differentially coding a similar disparity vector. The reliability can be increased through an accurate disparity using multiples of 8 rather than 16, in motion skip for sharing the format of a macroblock.
