We propose 3D angle decomposition methods from elastic reverse time migration using timeand space-lag common image point gathers, time-lag common image gathers, and space-lag common image gathers computed by elastic wavefield migration. We compute time-lag common image gathers at multiple contiguous locations, instead of isolated positions as is commonly done with common image gathers. Then, we...

Preserving invaluable historic recordings has drawn some interest because the traditional record playback system wears out the record gradually. This paper presents a non-contact method to reproduce sound signal from gramophone records using 3D scene reconstruction of the micro-grooves cast on a record surface. Because of the unique shape of the microgroove, a planar assumption was made during ...

An orientability measure determines how orientable a shape is; i.e. how reliable an estimate of its orientation is likely to be. This is valuable since many methods for computing orientation fail for certain shapes. In this paper several existing orientability measures are discussed and several new orientability measures are introduced. The measures are compared and tested on synthetic and real...

In this paper, we describe a software module for the animation of a virtual interpreter that translates from Italian to the Italian Sign Language (LIS). The system we describe takes a “synthetic” approach to the generation of the sign language, by composing and parametrizing pre-captured and hand-animated signs, to adapt them to the context in which they occur.

Maximum short segments of quantity in 120 discrimination tests at the word level were compared between twoand three-choice alternatives and with production test results utilising the same syllable structures. The materials in the perception test were eight kinds of bisyllabic synthetic nonsense words with five different prosodic patterns. These structures were used in the production test. 28 Fi...
