An 8-32 kbit/s scalable wideband coder extended with MDCT-based bandwidth extension on top of a 6.8 kbit/s narrowband CELP coder
In this paper, we present a 6.8-32 kbit/s scalable speech and audio coder using a modified-discrete-cosine-transform (MDCT)-based bandwidth extension on top of a 6.8 kbit/s code-excited-linear-prediction (CELP) coder. The proposed coder comprises a 6.8 kbit/s narrowband CELP as its corelayer and eight enhancement layers with the bitrates of 0.8, 1.2, 3.2, or 4.0 kbit/s. After encoding of a narr...
متن کاملCoding Wideband Speech at Narrow- Band Bit Rates
The 'rnuffl~d' quality of coded .peech, which arises from the handlimiling ofspeech to 4 kHz, can be reduced either by coding speed! with a wider bandwidth or by widcband enhancement of the narrowband coded speech. ThL~ paper investigates the limitations of wideband enbancement and pO)Ssibilities for its improvement A new wideband coding scheme is prop()sed thaI i. based 00 any narrowband coder...
متن کاملPlanelet Transform: A New Geometrical Wavelet for Compression of Kinect-like Depth Images
With the advent of cheap indoor RGB-D sensors, proper representation of piecewise planar depth images is crucial toward an effective compression method. Although there exist geometrical wavelets for optimal representation of piecewise constant and piecewise linear images (i.e. wedgelets and platelets), an adaptation to piecewise linear fractional functions which correspond to depth variation ov...
متن کاملCombined speech and audio coding with bit rate and bandwidth scalability
The growing demand for streaming multimedia services over the Internet and recently also over mobile networks has initiated a great interest in coding algorithms which are able to adapt to different transmission environments and to operate under multiple constraints of bit rate, complexity, delay, robustness to bit errors and diversity of input signals. In the light of these recent developments...
متن کاملEfficacy and tolerability of needling as an adjuvant to narrowband ultraviolet B therapy in the treatment of vitiligo: a clinical trial
Background: Despite great advances in therapeutic regimens,complete repigmentation in vitiligo is still out of reach. The aimof this assay was to study the efficacy and tolerability of repeatedneedling combined with narrowband ultraviolet B (NBUVB)therapy in the treatment of generalized, stable, refractory vitiligo.Method: Twenty-six patients with stable generalized intractablevitiligo were rec...
