摘要: A predictive coding method for coding intra of frames is revealed. Firstly, an encoder divides an image frame into a plurality of macroblocks. Then the encoder sets predictive coding models corresponding to these macroblocks according to a ratio. The encoder performs predictive coding for coding each macroblock according to the corresponding predictive coding model so as to get and output a coded image. By the present invention, various predictive coding models are set and applied to code the different macroblocks so as to increase predictive coding efficiency. The intra prediction efficiency and image compression efficiency are improved simultaneously.

摘要: The present invention relates to a method for motion estimation in multimedia images, which comprises steps of: dividing a predict image frame into a plurality of groups of macroblocks, and each of the groups of macroblocks including a plurality of macroblocks; predicting a motion vector of each of the groups of macroblocks, and producing a predict motion vector; producing one or more search windows according to the predict motion vector; and comparing a plurality of pixels in each macroblock of each group of macroblocks to a plurality of pixels in the search window, and producing an actual motion vector, respectively. Thereby, by gathering a plurality of macroblocks, a shared predict motion vector is produced for reducing computations in coding. Hence, the coding efficiency can be enhanced.
