PVQM – A perceptual video quality measure
Signal Processing: Image Communication, 2002Abstract Modern video coding systems such as ISO-MPEG1,2,4 exploit properties of the human visual system, to reduce the bit rate at which a video sequence is coded, given a certain required video quality. As a result, to the degree in which such exploitation is successful, accurate prediction of the quality of the output video of such systems, should

In “Perceptual Quality Space”, Keller offers an account of perceptual qualities such as the redness of a tomato or the characteristic smell of a rose. These perceptual qualities are the basic building blocks of perception. According to the account offered, perceptual qualities from all sensory modalities can be arranged in a multidimensional perceptual

High Quality Perceptual Steganographic Techniques
2004Recently, several steganographic algorithms for two-color binary images have been proposed [16,1,14,2]. In this paper, we propose steganographic algorithms which embeds a secret message into bitmap images and palette-based images. To embed a message, the suggested algorithm divides a bitmap image into bit-plane images from LSB-plane to MSB-plane for ...

Perceptual quality and objective quality measurements of compressed videos
Journal of Visual Communication and Image Representation, 2006Abstract This paper firstly presents a study of video quality for H.264 compressed videos compared to MPEG-4 (simple profile) from a perceptual point of view. Traditionally, peak signal-to-noise ratio (PSNR) has been used to represent the quality of a compressed video sequence.

The chapter begins with a review of several studies concerning the quality of TTS systems followed by a discussion of the restrictions of these studies. Afterwards, two studies on two extensive German TTS databases are presented. In the first study a SD is developed that covers all perceptual quality features of state-of-the-art TTS systems, while the ...

Perceptual speech quality assessment - a review
2004 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2004This paper reviews the development of perceptually-motivated models for quality assessment of speech transmission/storage systems. The aim is to predict a subjective mean opinion score (MOS) for non-linear, time-variant distortions such as lossy coders, channel errors or noise reduction, particularly for telecommunications applications.
