变均匀

In this paper, we propose a new approach to recognize occluded objects. The information of the magnitude of the local extreme of the open angles in the contour of a model at a scale, the information of the distance and relative location between the two adjacent dominant points are suitably integrated as a set of features for describing a model, the features are invariant under rotation, uniform scaling, and translation of the curve.

该文提出了一种新的识别有遮挡目标的方法，即将目标模型和含有目标的遮挡图象的轮廓在某一尺度上张角的极值、极值点之间距离、相对位置等信息集成在一起，作为描述目标模型的一组特征，且这组特征在平移、旋转和均匀尺度变换下保持不变。

This paper firstly discusses the principle of UWB pulse array beamforming. Then a beamforming scheme is presented based on multi-rate filter bank, which is suitable for UWB pulse signals. The proposed method avoids the hardness of delays control in time domain, and can obtain the uniform frequency invariant array response in such a wideband for UWB signals.
