Almost a ll voice communications are based on monophonic narrowband speech. Wideband stereophonic communications provide a more natural sounding environment. This holds especially true for teleconferencing applications, where the localization information in the stereo signal adds a new dimension to the communication. As of today, there is no standardized speech codec with full stereo support. S...

Catadioptric Omni-Directional Stereo Vision (ODSV) technology is the combination of omni-directional imaging and stereo vision, which has wide application potentials on robot vision and large-scale video surveillance [1-4]. Fig.1 gives the framework of ODSV technology, which includes four major parts: the design of omni-directional stereo vision imaging system, unwarping of omni-directional ste...

Materials and Methods Nanofluidic chips Nanofluidic chips were fabricated from a silicon wafer with 2 μm thermal oxide in cleanroom facilities at Chalmers University of Technology. Nanochannels were created by electron-beam lithography (JBX-9300FS/JEOL Ltd) and reactive ion etching (Plasmalab 100 ICP180/Oxford Plasma Technology). Microchannels were made by optical lithography (MA 6/Suss MicroTe...

Parabolic compound refractive lenses are high quality optical components for hard x rays. They are particularly suited for full field imaging, with applications in microscopy and x-ray lithography. Taking advantage of the large penetration depth of hard x rays, the interior of opaque samples can be imaged with submicrometer resolution. To obtain the three-dimensional structure of a sample, micr...

In this contribution we describe the application of Ink-Jet printing and Stencil Lithography in bionanotechnology. Both techniques are alternative patterning methods that can be used for the fabrication of biocompatible microand nanostructures out of the costly and restricted clean room environment. The applications presented in this contribution are 1) the cell patterning using Au dot arrays d...

A new illumination system for mask aligner lithography is presented. The illumination system uses two subsequent microlens-based Köhler integrators. The second Köhler integrator is located in the Fourier plane of the first. The new illumination system uncouples the illumination light from the light source and provides excellent uniformity of the light irradiance and the angular spectrum. Spatia...

The development of nanotechnology faces many problems, one of which is lack of a fast and cheap method for fabricating structures whose dimensions are less than 0.1 μm. One method to solve this problem is nanoimprint lithography (NIL). The method of fabricating nanometer scale patterns by NIL was first proposed by Chou1,2 in 1995. Nanoimprint lithography creates patterns by the mechanical defor...

This paper presents a novel approach to the problem of computing the matching-cost for stereo vision. The approach is based upon a Convolutional Neural Network that is used to compute the similarity of input patches from stereo image pairs. In combination with state-ofthe-art stereo pipeline steps, the method achieves top results in major stereo benchmarks. The paper introduces the problem of s...

In deep learning-based local stereo matching methods, larger image patches usually bring better accuracy. However, it is unrealistic to increase the size of patch without restriction. Arbitrarily extending will change method into global method, and accuracy be saturated. We simplified existing Siamese convolutional network by reducing number parameters propose an efficient CNN based structure, ...

Abstract Advances in direct laser writing to attain super-resolution are required improve fabrication performance and develop potential applications for nanophotonics. In this study, a novel technique using single-color peripheral photoinhibition lithography was developed the resolution of while preventing chromatic aberration characteristics conventional multicolor lithography, thus offering r...
