METHODS, APPARATUS, AND A COMPUTER PROGRAM PRODUCT FOR PROVIDING A FAST INTER MODE DECISION FOR VIDEO ENCODING IN RESOURCE CONSTRAINED DEVICES |
摘要 |
A device for reducing the number of motion estimation operations in performing motion compensated prediction includes a motion estimator, a motion compensated prediction device and a processing element. The motion estimator is configured to extract a motion vector from a macroblock of a video frame. The macroblock includes inter modes which are block sizes. The motion compensated prediction device is configured to generate a prediction macroblock based on the motion vector by analyzing a corresponding macroblock in a reference frame. The processing element communicates with the motion estimator and the motion compensated prediction device. The processing element also compares a distortion value to a first predetermined threshold and selects a first encoding mode among first and second encoding modes without evaluating the second encoding mode based upon the comparison of the distortion value to the first predetermined threshold. |
