Description: 运动估计是视频压缩中帧间预测编码的关键技术之一，在各个压缩标准中都广泛使用了基于块的运动估计技术。由于运动估计通常具有较大的运算量，因此对压缩性能具有重要的影响。本文在分析了视频序列的特点和对现有的快速搜索算法深入理解的基础上提出了一种改进的快速运动估计搜索算法，通过实验表明该算法对压缩性能有了较好的改进。

Description: The problem of image registration subsumes a number of problems and techniques in multiframe
image analysis, including the computation of optic flow (general pixel-based motion), stereo
correspondence, structure from motion, and feature tracking. We present a new registration
algorithm based on spline representations of the displacement field which can be specialized to
solve all of the above mentioned problems. In particular, we show how to compute local flow,
global (parametric) flow, rigid flow resulting from camera egomotion, and multiframe versions of
the above problems. Using a spline-based description of the flow removes the need for overlapping
correlation windows, and produces an explicit measure of the correlation between adjacent flow
estimates. We demonstrate our algorithm on multiframe image registration and the recovery of 3D
projective scene geometry. We also provide results on a number of standard motion sequences.

Description: The permanent magnet synchronous motors (PMSM) are used as servo motor for precise
motion control and are used as generator to generate electrical energy driven by wind energy.
There is large variation in inertia due to varying load and parametric uncertainty in PMSM.
The design objective of this paper is to analytically determine the relative robust stability of
PMSM with parametric uncertainty using Kharitonov theorem and Routh stability criterion.
The conventional integral controller (IC) and two robust internal model controllers (IMCs) are
used for relative robust stability analysis of speed control of PMSM. The frequency domain
performance specifications like gain margin (GM) and phase margin (PM) are taken for
relative robust stability analysis, and the effect of controllers on time domain performance
specifications such as settling time (ST), rise time (RT) and overshoot (OS) is also studied.
