31. Perceptual and Squared Error Aspects in Speech and Audio Coding
Sammanfattning : In the process of quantization, speech and audio signals are changed. This thesis contains four papers concerned with comparing and minimizing different measures to quantify the changes introduced. Before quantization the signal can be transformed to another domain. Transforms related to the discrete Fourier transform allow for e. LÄS MER

33. Synthesis, Coding, and Evaluation of 3D Images Based on Integral Imaging
Sammanfattning : In recent years camera prototypes based on Integral Imaging (II) have emerged that are capable of capturing three-dimensional (3D) images. When being viewed on a 3D display, these II-pictures convey depth and content that realistically change perspective as the viewer changes the viewing position. LÄS MER
34. On Robust LPC-spectrum Coding and Vector Quantization
Sammanfattning : Digital speech coding is concerned with representing a discrete-time speech signal with as few bits per second as possible without introducing annoying artifacts in the coded speech. Many modern speech coders are based on Linear Predictive Coding (LPC) which employ a source-filter model for speech production. LÄS MER
35. Linear Coding, Applications and Supremus Typicality
Sammanfattning : Detta arbete börjar med att presentera en kodningssats gällande linjärkodning över ändliga ringar för kodning av korrelerade diskretaminneslösa källor. Denna sats inkluderar som specialfall motsvarandeuppnåbarhetssatser från Elias och Csiszár gällande linjär kodning överändliga kroppar. LÄS MER
