Phase Retrieval and Hilbert Integral Equations – Beyond Minimum-Phase
(2018-07-18)
The Fourier transform (spectrum) of a signal is a complex function and is characterized by the magnitude and phase spectra. Phase retrieval is the reconstruction of the phase spectrum from the measurements of the magnitude ...
Perceptual Criterion Based Rate Control And Fast Mode Search For Spatial Intra Prediction In Video Coding
(2010-03-11)
This thesis dwells on two important problems in the field of video coding; namely rate control and spatial domain intra prediction. While the former is applicable generally to most video compression standards, the latter ...
Explicit Segmentation Of Speech For Indian Languages
(2010-07-02)
Speech segmentation is the process of identifying the boundaries between words, syllables or phones in the recorded waveforms of spoken natural languages. The lowest level of speech segmentation is the breakup and ...
