This paper proposes an image fusion algorithm based on a sparse linear equation system, which uses local extreme of high resolution image and intensity of multi-spectral image to construct the system. Based on this sparse system, the multi-scale image decomposition algorithm can be implemented. This algorithm extracts the details of the high-resolution image and integrates with the multi-spectral...
We present a passive acoustic apparatus for maternal abdominal fetal heart rate (FHR) monitoring. The apparatus consists of an acoustic sensor module and a Laptop or a PDA embedded with signal processing algorithms. It is able to provide a calculated fetal heart rate instantaneously, real-time fetal heart sound waveform displays and audio playback. The fetal heart sound signals are detected, de-noised...
The aim of this study was to develop a reliable automated method of QT interval measurement for ECG signals, and to participate the PhysioNet/Computers in Cardiology Challenge 2006. A scheme based on Kalman filter was proposed to conduct beat segmentation and searching of the first representative beat from ECG waveform, and a wavelet based algorithm was used to detect the onset of QRS complex and...
