An Efficient Algorithms for Optimal Block Motion Estimation

This paper presents an efficient algorithm for reducing and dynamically controlling the computational complexity of an H.264 video encoder implemented in software. We also therefore address a power-aware Motion Estimator for H.264 which can adapt at run time according to the available energy level. Experiments prove that our algorithm is not only dramatically improve the performance of resource constrained multimedia systems but also can optimize the rate distortion optimization procedure to the four groups selectively.

Low-cost Monitoring and Control for Multi-dimensional Time

An important class of statically-analyzable loops is affine control loops (ACLs). Expected value signals related to fluid preference, the expected magnitude, or probability of reward were decoded simultaneously with the intended goal. An inverse method was also used by previous investigators to reconstruct the input signal of a saccade from the Fourier transform of the padded and mirrored position profile and the impulse response of the system model. In this paper, we present the application of independent component analysis (ICA) to decompose the components of saccade and vergence eye movements.
