Waveform similarity based overlap-add (WSOLA) for time-scale modification of speech: structures and evaluation
A synchronization criterion for overlap-add time-scale modification is derived through a least squares estimation of the modified short-time Fourier transform. Based on this finding, a structural time-domain framework for time-scale modification is described. One efficient variant, which was called the Waveform Similarity based Overlap-Add (WSOLA) method, produces high quality output when appli...
متن کاملFast Normalized Cross-Correlation
Although it is well known that cross correlation can be efficiently implemented in the transform domain, the normalized form of cross correlation preferred for feature matching applications does not have a simple frequency domain expression. Normalized cross correlation has been computed in the spatial domain for this reason. This short paper shows that unnormalized cross correlation can be eff...
متن کاملFast normalized cross correlation for defect detection
Normalized cross correlation has been used extensively for many machine vision applications, but the traditional normalized correlation operation does not meet speed requirements for time-critical applications. In this paper, we propose a fast normalized cross correlation computation for defect detection application. A sum-table scheme is utilized, which allows the calculations of image mean, i...
متن کاملAn Overlap-add Technique Based on Waveform Similarity (wsola) for High Quality Time-scale Modification of Speech
A concept of waveform similarity is proposed for tackling the problem of time-scale modification of speech, and is worked-out in the context of short-time Fourier transform representations. The resulting WSOLA algorithm produces high quality speech output, is algorithmically and computationally efficient and robust, and allows for on-line processing with arbitrary timescaling factors that may b...
متن کاملTemplate Matching using Fast Normalized Cross Correlation
In this paper we present an algorithm for fast calculation of the normalized cross correlation NCC and its applica tion to the problem of template matching Given a template t whose position is to be determined in an image f the basic idea of the algorithm is to represent the template for which the normalized cross correlation is calculated as a sum of rectangular basis functions Then the correl...
