拉格朗日乘数法在H.264视频编码中的应用。

Use adaptive frame/field picture coding mode.

Decision is based on lagrangian RDO of the form <?xml:namespace prefix = v ns = "urn:schemas-microsoft-com:vml" /><shapetype id="_x0000_t75" stroked="f" filled="f" path="m@4@5l@4@11@9@11@9@5xe" o:preferrelative="t" o:spt="75" coordsize="21600,21600"><stroke joinstyle="miter"></stroke><formulas><f eqn="if lineDrawn pixelLineWidth 0"></f><f eqn="sum @0 1 0"></f><f eqn="sum 0 0 @1"></f><f eqn="prod @2 1 2"></f><f eqn="prod @3 21600 pixelWidth"></f><f eqn="prod @3 21600 pixelHeight"></f><f eqn="sum @0 0 1"></f><f eqn="prod @6 1 2"></f><f eqn="prod @7 21600 pixelWidth"></f><f eqn="sum @8 21600 0"></f><f eqn="prod @7 21600 pixelHeight"></f><f eqn="sum @10 21600 0"></f></formulas><path o:connecttype="rect" gradientshapeok="t" o:extrusionok="f"></path><?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><lock aspectratio="t" v:ext="edit"></lock></shapetype><shape id="_x0000_i1025" style="WIDTH: 126pt; HEIGHT: 14.25pt" o:ole="" type="#_x0000_t75"><imagedata o:title="" src="file:///C:/DOCUME~1/ADMINI~1/LOCALS~1/Temp/msohtml1/01/clip_image001.wmz"></imagedata></shape>where Distortion is the SSE distortion of the entire reconstructed frame (or both fields), λ is the lagrangian parameter, and Rate is the allotted bits for coding the frame (or fields respectively). 说的很清楚啦，在JVT-Q042.doc文档的Page-4-40页面。一下让我明白了很多，看来学要别人指点呢。
