This paper presents low-complexity algorithm for fractional-pixel motion estimation (FME). The proposed algorithm uses a mathematical model to approximate the matching error at fractional-pixel locations. Hence, no interpolation is required at fractional-pixel locations. The matching error values at integer-pixel locations are used to evaluate the model coefficients. The performance of the proposed...
Motion Estimation/Compensation is one of the most critical modules in a typical digital video encoder. Many implementation tradeoffs should be considered while designing such a module. This paper focuses on the implementation of several motion estimation algorithms and investigates the differences between them according to different evaluation metrics. The algorithms are evaluated with respect to...
