详细的介绍了清华大学的matlab7.0的工作原理(Described in detail the working principle of Tsinghua University matlab7.0)

自适应算法,根据空域相邻块的运动水平,自适应地选择搜索策略,对于小运动块,充分利用中心偏置特性提高算法速度,对大运动块则利用多候选值算法力求得到真实的全局最小值,以确保对各种不同的图像序列都有较高的搜索速度和准确度(Adaptive algorithm, in accordance with the airspace adjacent to the level of block movement, adaptive search strategy to choose, for a small movement blocks, take full advantage of center-biased characteristics of algorithms improve the speed of movement of large pieces of the algorithm using multi-candidate seeks to be the true value of the overall situation minimum, to ensure a variety of image sequences have a high search speed and accuracy)

计算正弦信号加噪声的相关函数。系数b 决定余弦相关函数在噪声指数型相关函数中的“比重”。T为正弦信号周期。正弦信号加相关噪声的相关函数图像为一个指数函数和一个余弦函数叠加的波形。(Calculated sinusoidal signal plus noise correlation function. Coefficient b determine the cosine correlation function in the noise correlation function of exponential type in " proportion." T for the sinusoidal signal cycle. Sinusoidal signal plus noise correlation function related to the image as an index function and a cosine function superimposed waveform.)
