abstract = "In this paper, we propose two new algorithms for high quality
motion estimation in high definition digital videos. Both
algorithms are based on the use of random features that guarantee
robustness to avoid dropping into a local-minimum. The first
algorithm was developed from a simple two stage approach where a
random stage is complemented by a greedy stage in a very simple
fashion. The second algorithm is based on a more refined class of
algorithms called Memetic Network Algorithms where each instance
of the search may exchange information with its neighbour
instances according to some rules that control the information
flow. The proposed algorithms were implemented and tested
exclusively with high definition sequences against well known fast
algorithms like Diamond Search and Three Step Search. The results
show that our algorithms can outperform other algorithms in
quality yielding an increment in complexity that may be amortized
if resources for a parallel execution are available. Additionally,
we provide further evidence that fast algorithms do not perform
well in high definition.",
