In this paper we describe a lossless coding scheme for the encoding of MPEG-1 Layer III encoded audio bitstreams. Commonly known as MP3, the MPEG-1 Layer III standard has proved widely popular for the transmission of encoded audio les (MP3's) over the Internet. However, the MPEG-1 Layer III standard has been designed with a wide range of applications in mind. As such, the frame sizes are kept s...

 In this paper, utilization of clustering algorithms for data fusion in decision level is proposed. The results of automatic isolated word recognition, which are derived from speech spectrograph and Linear Predictive Coding (LPC) analysis, are combined with each other by using fuzzy clustering algorithms, especially fuzzy k-means and fuzzy vector quantization. Experimental results show that the...

This paper proposes a feature extraction method for gesture recognition, which is based on higher order local autocorrelation (HLAC) of PARCOR images. To extract dominant information from a sequence of images, we apply linear prediction coding technique to the sequence of pixel values and PARCOR images are constructed from the PARCOR coe cients of the sequences of the pixel values. Then HLAC fe...

We describe a compression scheme for the geometry component of 3D animation sequences. This scheme is based on the principle component analysis (PCA) method, which represents the animation sequence using a small number of basis functions. Second-order linear prediction coding (LPC) is applied to the PCA coefficients in order to further reduce the code size by exploiting the temporal coherence p...

In this paper, interpolation of linear predictive coding (LPC) parameters in terms of the following representations is investigated: linear prediction coefficient representation, reflection coefficient representation, log-arearatio representation, arc-sine reflection coefficient representation, cepstral coefficient representation, line spectral frequency representation, autocorrelation coeffici...

Introduction People can perceive differences in vocal effort between voices, even when the pitch is the same and sound levels have been normalized. In this situation, the largest indicator of vocal effort is the amount of high-frequency content in the voice relative to low frequency content (Figure 1). The goal of this research is to use linear prediction coding to modify the perception of voca...

In addition to the many industrial robots that support our daily lives, there are numerous fictional robots that have appeared in movies, comics, and video games. Many of us would be interested in understanding the experience of having a tough iron body, and perhaps even wish that we could become like these robotic heroes, if only for a short time. The question naturally arises: What would it f...

Development of effective heat treatments is crucial to achieve food products safety, and predictive microbiology is an excellent tool to design adequate processing conditions. This work focuses on the application of a modified Gompertz model to describe the inactivation behaviour under time-varying temperature conditions at the surface of a food product. Kinetic studies were carried out assumin...

Sociophonetic real-time studies of vowel variation and change rely on acoustic analyses of sound recordings made at different times, often using different equipment and data collection procedures. The circumstances of a recording are known to affect formant tracking and may therefore compromise the validity of conclusions about sound changes made on the basis of real-time data. In this paper, a...
