Scalable virtual viewpoint image synthesis for multiple camera environments [PDF]
, 2005 One of the main aims of emerging audio-visual (AV) applications is to provide interactive navigation within a captured event or scene. This paper presents a view synthesis algorithm that provides a scalable and flexible approach to virtual viewpoint ...

Hybrid Blind Audio Watermarking for Proprietary Protection, Tamper Proofing, and Self-Recovery
IEEE Access, 2019 The paper presents a lifting wavelet transform (LWT)-based framework for multi-purpose blind audio watermarking. The proposed schemes can be used to carry out robust watermarking for intellectual property protection as well as fragile watermarking for ...

Coding overcomplete representations of audio using the MCLT [PDF]
, 2008 We propose a system for audio coding using the modulated complex lapped transform (MCLT). In general, it is difficult to encode signals using overcomplete representations without avoiding a penalty in rate-distortion performance.

Towards a new perceptual coding paradigm for audio signals [PDF]
2003 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2003. Proceedings. (ICASSP '03)., 2004 A new frequency domain approach to coding audio signals is introduced. The bit assignment strategy is aimed at reducing the perceived loudness difference between the original signal and the coded signal. As such it uses perceptual effects (spread excitation patterns), but does not directly invoke masking results.

On Macroscopic Complexity and Perceptual Coding [PDF]
, 2011 The theoretical limits of 'lossy' data compression algorithms are considered. The complexity of an object as seen by a macroscopic observer is the size of the perceptual code which discards all information that can be lost without altering the perception

Perceptually Motivated Wavelet Packet Transform for Bioacoustic Signal Enhancement [PDF]
, 2008 A significant and often unavoidable problem in bioacoustic signal processing is the presence of background noise due to an adverse recording environment. This paper proposes a new bioacoustic signal enhancement technique which can be used on a wide range

Detection of Montage in Lossy Compressed Digital Audio Recordings
Archives of Acoustics, 2014 This paper addresses the problem of tampering detection and discusses methods used for authenticity analysis of digital audio recordings. Presented approach is based on frame offset measurement in audio files compressed and decoded by using perceptual ...

Perceptual filter design for audio coding usingpsychoacoustic modelling
Electronics Letters, 1998 A generalised perceptual filter which aims to reduce the audible quantisation noise in low bit rate audio coding has been developed. The filter derivation is based on a psychoacoustic excitation pattern model. Experimental results show that the perceptual filter can reduce the audible quantisation noise in a sub-band coded audio signal.

Visual Feature Domain Audio Coding for Anomaly Sound Detection Application
AlgorithmsConventional audio and video codecs are designed for human perception, often discarding subtle spectral cues that are essential for machine-based analysis. To overcome this limitation, we propose a machine-oriented compression framework that reinterprets

Harmonic Enhancement in Low Bitrate Audio Coding Using an Efficient Long-Term Predictor
EURASIP Journal on Advances in Signal Processing, 2010 This paper proposes audio coding using an efficient long-term prediction method to enhance the perceptual quality of audio codecs to speech input signals at low bit-rates.
