storaging or transmission of speech signals at very low bit rate is a hot area in the field of speech processing. we used stochastic inter-frame interpolators and vector quantization (vq) as a new method for developing a high quality 1200 bps speech vocoder. the objective and subjecgtive test results show that performance of the new vocoder is compairable with 4800 bps standard vocoders (as celp).

Al~a'aet. We describe an extension of the single-frame visual field reconstruction problem in which we consider how to efficiently and optimally fuse multiple frames of measurements obtained from images arriving sequentially over time. Specifically we extend the notion of spatial coherence constraints, used to regularize single-frame problems, to the time axis yielding temporal coherence constr...

Face verification and recognition problems have seen rapid progress in recent years, however recognition from small size images remains a challenging task that is inherently intertwined with the task of face super-resolution. Tackling this problem using multiple frames is an attractive idea, yet requires solving the alignment problem that is also challenging for low-resolution faces. Here we pr...

This paper describes a novel feature tracking method. It is based on an interframe relaxation technique. This method combines intra-frame and inter-frame constraints on the behaviour of acceptable contour structure. The intra-frame information is represented by both a dictionary of local contour structure and a statistical model of the response of a set of directional feature detection operator...

In this paper, we present a novel method for multi-frame superresolution (SR). Our main goal is to improve the spatial resolution of a multi-line scan camera for an industrial inspection task. High resolution output images are reconstructed using our proposed SR algorithm for multi-channel data, which is based on the trainable reaction-diffusion model. As this is a supervised learning approach,...

This paper aims to assess the application of Support Vector Machine (SVM) regression in order to analysis flexible pavements. To this end, 10000 Four-layer flexible pavement sections consisted of asphalt concrete layer, granular base layer, granular subbase layer, and subgrade soil were analyzed under the effect of standard axle loading using multi-layered elastic theory and pavement critical r...

Multi-ribbed frame grid (hereinafter referred to as MRFG) is an important part of Multi-ribbed composite wall and consisted of outer frame and ribbed grid. The reinforcement of outer frame is the main influence factor on the performance of MRFG. In this study, an MRFG specimen under laterally cyclic and axial loading in literature is numerically simulated with 5 kinds of different reinforcement...

This article presents an analytic approach to study admissibility conditions related to classical full wavelet systems over finite fields using tools from computational harmonic analysis and theoretical linear algebra. It is shown that for a large class of non-zero window signals (wavelets), the generated classical full wavelet systems constitute a frame whose canonical dual are classical full ...

We propose a unified framework for the analysis of estimators of geometrical vector quantities and vector systems through a collection of performance measures. Unlike standard performance indicators, these measures have intuitive geometrical and physical interpretations, are independent of the coordinate reference frame, and are applicable to arbitrary parameterizations of the unknown vector or...
