TLDR
A new recursive block-matching motion estimation algorithm with only eight candidate vectors per block is presented and is shown to have a superior performance over alternative algorithms, while its complexity is significantly less.Abstract:
A new recursive block-matching motion estimation algorithm with only eight candidate vectors per block is presented. A fast convergence and a high accuracy, also in the vicinity of discontinuities in the velocity plane, was realized with such new techniques as bidirectional convergence and convergence accelerators. A new search strategy, asynchronous cyclic search, which allows a highly efficient implementation, is presented. A new block erosion postprocessing proposal further effectively eliminates block structures from the generated vector field. Measured with criteria relevant for the field rate conversion application, the new motion estimator is shown to have a superior performance over alternative algorithms, while its complexity is significantly less. >read more

New frame rate up-conversion using bi-directional motion estimation
TL;DR: The proposed frame rate up-conversion algorithm does not produce any overlapped pixel and hole region in the interpolated frame, and thus can utilize the overlapped block motion compensation technique to reduce the blocking artifacts.

Motion estimation and motion-compensated interpolation
TL;DR: In this article, at least two motion parameter sets are generated from input video data (n, n-1), a motion parameter set being a set of parameters describing motion in an image, by means of which motion parameters can be calculated.
