Variable Block size Motion Estimator

چکیده
Background. The class on complexity goes through how to design a fixed block size motion estimator. It is useful to have reviewed that class before proceeding with this document. Basically, often in video the only difference between much of the content in subsequent frames is motion (imagine panning a camera slowly over a fixed scene). If this is true the difference between subsequent frames can be coded solely as a set of motion vectors, indicating the translation. This provides a very high level of compression.

Adaptive Motion Estimator Based on Variable Block Size Scheme
This paper presents an adaptive motion estimator that can be dynamically reconfigured by the best algorithm depending on the variation of the video nature during the lifetime of an application under running. The 4 Step Search (4SS) and the Gradient Search (GS) algorithms are integrated in the estimator in order to be used in the case of rapid and slow video sequences respectively. The Full Sear...
