This paper presents a novel approach that performs post-processing for stereo matching. We improve the performance of stereo matching by performing consistency check and adaptive filtering in an iterative filtering scheme. The consistency check is only done with asymmetric information so that very few additional computational loads are necessary. The information in the valid pixels is propagate...

In this paper we describe a constraint based formalism that manipulates sequences of morphological analyses in order to Kill, Unify, Replace or Delete parts of the structure. We compare the formalism to a similar approach (CGP) and describe two applications.

Fractal image compression is a block based technique. The blocks of the underlying image partition are called range blocks. Like all block based techniques, fractal coding suffers from blocking artifacts, in particular at high compression ratios. Moreover, due to the recursive nature of the fractal decoder blocking artifacts also show up in the interior of the range blocks. This paper proposes ...

Vector field visualization is an important topic in scientific visualization. The aim is to graphically represent field data in an intuitively understandable and precise way. Two novel methods are described which enable an easy perception of flow data. The texture transport method especially applies to timedependent velocity fields. Lagrangian coordinates are computed solving the corresponding ...

A psychometric study was conducted in order to collect basic information about post-event processing in social anxiety. It was found that such processing occurs commonly after an anxiety-evoking or embarrassing social event and post-event processing scores were significantly correlated (r = 0.40) with social anxiety. The recollections of the social event tended to be recurrent and intrusive, in...

3D shape acquisition has become a major tool for creating digital 3D surface data in a variety of application fields. Despite the steady increase in accuracy, most available scanning techniques cause severe scanning artifacts such as noise, outliers, holes, or ghost geometry. To apply sophisticated modeling operations on these data sets, substantial post-processing is usually required. In this ...

This work describes an optimization technique which is applied to post-process byte-code instructions. By extending a virtual machine of an instruction set, some sequence of byte-codes can be represented by a shorter code which can be executed faster. The experimental result showed that this technique yielded 25% 120% speedup on Stanford integer benchmark suite. 1. Motivation This work describe...

It is generally thought that mean luminance and low spatial frequency information in a visual image are sharply attenuated at the retina, due to processes of light adaptation and the spatial filtering effects of lateral inhibition. Our results from interocular luminance masking suggest, however, that cortical masking effects play a primary role in the attenuation of low frequency sensitivity. R...

We investigate an automatic dialogue segmentation method using both verbal and non-verbal modalities. Dialogue contents are used for the initial segmentation of dialogue; then, gesture occurrences are used to remove the incorrect segment boundaries. A unique characteristic of our method is to use verbal and non-verbal information separately. We use a three-party dialogue that is rich in gesture...

Taking benefit of OASIS3-MCT interpolation facilities, an new output system called PoCO (Post-Processing Coupled with Oasis) has been design to replace the existing ARPEGE output library (FULLPOS). Several independent executables were coupled with ARPEGE to receive diagnostic variables that can be interpolated on different grids and written in Netcdf format, asynchronously to ARPEGE calculation...
