The mosaic generation methods benefit from recent global motion estimation (GME) methods, which yield almost accurate estimation of motion parameters. However, the generated mosaics are usually more blurred than original frames due to image warping stage and errors in motion estimation. The transformed coordinates resulting from GME are generally real numbers whereas images are sampled into int...

In this paper, we present ideas to combine VTLN and SAT to improve the performance of automatic speech recognition. We show that VTLN matrices can be used as SAT transformation matrices in recognition, though the training still follows conventional SAT. This will be useful when there is very little adaptation data and the SAT transformation matrix can not be estimated to perform the required ad...

Using gauge invariant effective Lagrangians in 1+ 3 dimensions describing the Standard Model in 1 + 4 dimensions, we explore dynamical electroweak symmetry breaking. The Top Quark Seesaw model arises naturally, as well as the full CKM structure. We include a discussion of effects of warping, and indicate how other dynamical schemes may also be realized. ∗e-mail: [email protected], hill...

The compact representation of the discrete amplitude spectrum of voiced speech by an all-pole model of the spectral envelope is considered. Based on the properties of the all-pole modeling error, the use of spectrum predistortion for improving the perceptual fit at low model orders is motivated. Warping of the frequency scale before modeling of the spectral envelope of narrowband voiced sounds ...

Bound documents either scanned or captured with digital cameras often present a geometrical warp that makes text-lines curled. The identification of text-lines is one of the steps for document de-warping when only a single image is available. This paper presents a new method for text-line segmentation. It is based on a simple, but effective, skew detector proposed by ÁvilaLins and simplifies th...

Seismic data are recorded and commonly interpreted in vertical two-way time; well logs, measured in depth, must be tied to seismic using a time-depth curve. However, well ties contain a large amount of uncertainty due to errors in the generation of synthetic seismograms and manual matching of synthetic seismograms to seismic traces. Using dynamic time warping, a fast algorithm that optimally al...

Problem statement: Optical flow inter-frame enhancement is one of the techniques to improve the quality of ultrasound images by reducing the speckle noise. The performance depends on accuracy of the optical flow inter-frame reconstruction which is a part of the technique. The speckle noise of an ultrasound image forms certain pattern, of which size of the speckle varies depends on the distance ...

In this paper two methods, an area based matching and a so called dynamic line warping, for generating digital surface models (DSMs) from IKONOS image pairs are compared and their limitations and usability for the rapid generation of good DSMs are discussed. The new dynamic line warping method is based on techniques used in speech recognition for warping corresponding epipolar lines of the ster...

Introduction. When dealing with time series, the application of a smoothing filter (to get rid of random fluctuations and better recognise the relevant structure) is usually one of the first steps. In the literature on time series similarity measures, however, the impact of smoothing is not explicitly or systematically considered – despite extensive experiments in, e.g., [2]. Instead, complex s...
