This paper proposes a constrained two-layer compression technique for electrocardiogram (ECG) waves, of which encoded parameters can be directly used for the diagnosis of arrhythmia. In the first layer, a single ECG beat is represented by one of the registered templates in the codebook. Since the required coding parameter in this layer is only the codebook(More)
Effective rejection of time-varying clutter originating from slowly moving vessels and surrounding tissues is important for depicting hemodynamics in ultrasound color Doppler imaging (CDI). In this paper, a new adaptive clutter rejection method based on spectral analysis (ACR-SA) is presented for suppressing nonstationary clutter. In ACR-SA, tissue and flow(More)
— In this paper, a new novel sound field processing system is proposed. This sound field processing system assists listeners in perceiving audible characteristics of a given movie theater or hall, especially with regard to distance and spatial impression. To extend sound space artificially, conventional algorithms reproduce reflected sounds based on the(More)
