We introduce a novel region-based video compression framework that uses a morphological operation to eeciently capture motion correspondences between consecutive frames in an image sequence. Our coder is built on the observation that the motion eld associated with typical image sequences can be segmented into component motion subbeld \clusters" associated with distinct objects or regions in the...

In this paper, we develop a hierarchical global motion estimation/compensation system which is used to improve the block-based motion compensation in the current low bitrate video coding standard H.263. The system first detects the background motion by examining the local motion information using hierarchical block matching and global motion estimation algorithm. If the background motion exists...

Managerial Hedging and Incentive Compensation in Stock Market Economies Incentive compensation exposes managers to the risk of their firms. Managers can hedge their aggregate risk exposure by trading in financial markets, but cannot hedge their firmspecific exposure. This gives them an incentive to pass up firm-specific projects in favor of standard projects that contain greater aggregate risk....

In this work, various dispersion compensation methods are designed and evaluated to search for a cost-effective technique with remarkable dispersion compensation and a good pulse shape. The techniques consist of different chirp functions applied to a tanh fiber Bragg grating (FBG), a dispersion compensation fiber (DCF), and a DCF merged with an optimized linearly chirped tanh FBG (joint techniq...

This article proposes and analyzes two possible methods to compensate the raw near-field data obtained with an array of probes. The first method is based on spatial compensation procedure for a single probe modified toward second use standard spectral (plane wave) single-probe compensation. To latter, guidelines how design modify overall measurement such that mutual coupling edge effects have l...

H.264 video standard introduces fractional pixel motion compensation technology to obtain a more precise motion vector and a higher compression ratio. But, it increases the complexity of the motion compensation process at the same time. In order to solve the difficulties, we analysis the procedure of fractional-pel interpolation in H.264 and propose a fast fractional-pel interpolation algorithm...

Introduction: Two-dimensional (2D) breath-hold and ECG-triggered cine MRI is frequently used to assess cardiac function. However this technique requires cooperation from the patient, and the MR acquisition has to be synchronized with the cardiac cycle using ECG. To control respiratory motion, the subject has to perform breath-holds or the position of the diaphragm has to be tracked using a resp...

Intentional actions may be a consequence of the endogenous compensation of a drop in excitability after damage induced by a motivational excitation. A neuron does not support factors of its inner environment within the scope of the predetermined standard at the expense of the alteration of other values. The only exception is the level of damage, which neuron tries to decrease by mean of homeost...

In this paper, we propose a novel method to compensate the effect of the noise for Automatic Speech Recognition in car environments. This method can be applied to recognizers using a standard MFCC front-end. We perform a channel-by-channel compensation of the noise effect in the filter-bank output domain. In a first stage, the parameters describing the noise are estimated and secondly, we estim...
