提出一种利用小波包变换逼近信号消除心电图ECG基线漂移噪声的方法。该方法的基本思想是：通过对 ECG信号进行多分辨率分析，利用所得到的一段或几段逼近信号充分逼近ECG信号中的基线漂移噪声的特性，从而 消除某线漂移分景。-Presents a wavelet packet transform approximation signal method to eliminate electrocardiogram ECG baseline drift noise. The basic idea

As PTZ (Pan–Tilt–Zoom) cam-eras are able to obtain multi-view-angle and multi-resolution information, they have received more and more concern in both research and real application. Stereo vision using dual-PTZ-camera system, com-pared with using d

The wavelet transform divides image into different but interrelated multi-resolution and multi-level sub-bands, so quantization coding strategy of image wavelet coefficient has great flexibility. To address to energy aggregation and correlated fe
