The H.264 encoder allows 2 intra coding modes and 5 inter coding modes for a macroblock in a P slice. This is the most essential part for high compression efficiency but requires many computations to decide the most suitable coding mode. In this paper, we present a fast mode decision algorithm for H.264 P slices. To reduce complexity, we analyze the results of 16 x 16 ME (motion estimation) of a macroblock according to the proposed decision model, and if this macroblock is considered to be coded with a larger mode, we prevent motion estimations for smaller modes."andybeachhttps://www.blogger.com/profile/06309707016260546279noreply@blogger.comtag:blogger.com,1999:blog-9949735.post-16649290753008067312008-07-25T15:30:00.000-07:002008-07-25T15:30:00.000-07:00RWVC is there, and the book was a pleasure -- with...RWVC is there, and the book was a pleasure -- with plenty of nougats for everyone.<BR/><BR/>Hey, do you know if h.264 is indeed optimized for 16x16 image dimensions? An Adobe resource seems to indicate this:<BR/>http://www.adobe.com/devnet/flash/apps/flv_bitrate_calculator/video_sizes.html<BR/><BR/>RichRichhttps://www.blogger.com/profile/04573955585806562627noreply@blogger.comtag:blogger.com,1999:blog-9949735.post-41295691207451307342008-07-25T14:39:00.000-07:002008-07-25T14:39:00.000-07:00thanks for the review! please consider adding my ...thanks for the review! please consider adding my RWVC site you your blog roll as well. i am continuing to post topics related to video and am finalizing a format now for sharing video tutorials.<BR/><BR/>cheers,<BR/><BR/>andy beachandybeachhttps://www.blogger.com/profile/06309707016260546279noreply@blogger.com
