The analyses of beat to beat fluctuations of heart rate known as heart rate variability (HRV) become a non-invasive clinical tool to study the modulation that the autonomic nervous system exerts on the cardiovascular system. HRV presents a complex behaviour that may contain hidden information, which may not extractable with conventional methods of HRV analysis. Linear HRV measures are not able to detect these subtle but important properties. Thus several methods to describe non-linear heart rate dynamics have been developed. These methods include chaotic analyses, graphical representation and...

Image Compression plays a very important role in all multimedia services by reducing the number of bytes or bandwidth required to store or transmit the data. A real time based approach for image compression have been developed with the help of hierarchical decomposition and prediction. Keeping in view, the need of hour, this book should help to understand the consequences of hierarchical decomposition and prediction on predicted and reconstructed images. Analysis have been created for maximum level of decomposition of image. Proposed approach is implemented on distinct image file formats to...
