Fast multiplerun_beforedecoding method for efficient implementation of an H.264/advanced video coding context-adaptive variable length coding decoder [PDF]
Optical Engineering, 2013 We propose a fast new multiple run_before decoding method in context-adaptive variable length coding (CAVLC). The transform coeffi- cients are coded using CAVLC, in which the run_before symbols are gen- erated for a 4 × 4 block input. To speed up the CAVLC decoding, the run_before symbols need to be decoded in parallel. We implemented a new CAVLC table

About adaptive coding on countable alphabets [PDF]
, 2014 This paper sheds light on universal coding with respect to classes of memoryless sources over a countable alphabet defined by an envelope function with finite and non-decreasing hazard rate. We prove that the auto-censuring AC code introduced by Bontemps

Speaker Normalization Using Cortical Strip Maps: A Neural Model for Steady State Vowel Identification [PDF]
, 2007 Auditory signals of speech are speaker-dependent, but representations of language meaning are speaker-independent. Such a transformation enables speech to be understood from different speakers.
