| 20090110066 | Method and Apparatus for Selecting a Coding Mode - A method and apparatus for selecting a coding mode for a block of a current picture are disclosed. For example, the method selects a coding mode in accordance with a cost function, for coding the block, wherein the cost function comprises a coding distortion parameter and a number of coding bits parameter, wherein said coding distortion parameter is measured in accordance with at least one of: between a prediction residual and a reconstructed prediction residual, or between a transformed prediction residual and a dequantized transformed prediction residual, wherein the number of coding bits parameter is computed in accordance with at least one of: from a true number of compressed bits resulting from coding said block, directly from a plurality of bins, or directly from a plurality of quantized transform coefficients. | 04-30-2009 |
| 20100061458 | METHOD AND APPARATUS FOR FAST MOTION ESTIMATION - Embodiments of the invention generally provide a method and apparatus for fast motion estimation. One embodiment of a method for motion estimation includes classifying a macroblock of a source frame in accordance with an initial matching cost, an intermediate matching cost, and a final matching cost, where the intermediate matching cost is estimated based on a predicted motion vector for the source frame and the final matching cost is estimated based on a final motion vector for a correlated macroblock in a prior frame, performing motion estimation for the macroblock based upon the classifying, wherein an early termination is applied in accordance with a result of the classifying, and outputting a motion vector for the macroblock based on a result of the motion estimation. | 03-11-2010 |
| 20100061459 | METHOD AND APPARATUS FOR COMPLEXITY-SCALABLE MOTION ESTIMATION - Embodiments of the invention generally provide a method and apparatus for complexity-scalable video coding. One embodiment of a method for video coding includes receiving a sequence of one or more video frames, obtaining a budget for the one or more video frames, the budget specifying a maximum number of computations that may be used in performing motion estimation for the one or more video frames, allocating the maximum number of computations among individual ones of the one or more video frames, performing motion estimation in accordance with the allocating, and outputting a motion estimate for the sequence. | 03-11-2010 |
