Title: Innovations by Mark R Sydorenko
Introduction
Mark R Sydorenko is an accomplished inventor based in Plainfield, NJ (US). He holds a total of 3 patents that showcase his expertise in data compression methods and audio signal processing. His innovative approaches have significantly contributed to the fields of audio and video technology.
Latest Patents
One of his latest patents is a data compression method and apparatus. This invention provides a method for measuring the 'perceptual distance' between an approximate, reconstructed representation of a sensory signal and the original sensory signal. The perceptual distance serves as a quantitative measure of how likely a human observer can distinguish between the original and reconstructed signals. This method is particularly useful for noisy compression techniques, allowing for the allocation of bits in audio and video compression algorithms to ensure that the reconstructed signal remains perceptually similar to the original. The approach is grounded in a theory of the neurophysiological limitations of human sensory perception, utilizing a neural encoding model (NEM) to analyze sensory signals in the human brain.
Another significant patent by Sydorenko focuses on tonality for perceptual audio compression based on loudness uncertainty. This technique employs recent research into the psycho-physics of noise masking in the human auditory system. By determining the masking effect of an audio signal, this method enables transparent compression at reduced bit rates. It utilizes measures of loudness uncertainty to form noise masking thresholds, ensuring that the encoded audio signal maintains a loudness differential that is minimally perceptible to the human ear.
