Hypnosis is a potentially valuable cognitive tool for neuroimaging studies. However, understandable concern that Magnetic Resonance Imaging (MRI) in particular may adversely affect hypnotic procedures remains. Measurements of hypnotic depth and responsiveness to suggestions were taken using a standardized procedure that met all the requirements for functional MRI (fMRI). Testing outside the sca...

Introduction: Obtaining reliable depth maps, indicating distance of surface from the stereo camera pair, have importance in robotic applications and autonomous systems. Intelligent systems, which can move around by itself, could be developed by obtaining dept information from the sensors. Stereovision is the one of methods that can yield dept information of the scene. It uses stereo image pairs...

Autonomous navigation behaviors in robotics often require reliable depth maps. The use of vision sensors is the most popular choice in such tasks. On the other hand, accurate vision-based depth computing methods suffer from long execution times. This paper proposes a novel quad-camera based system able to calculate fast and accurately a single depth map of a scenery. The four cameras are placed...

Reliable prediction of groundwater depth fluctuations has been an important component in sustainable water resources management. In this study, a data-driven prediction model combining discrete wavelet transform (DWT) preprocess and support vector machine (SVM) was proposed for groundwater depth forecasting. Regular artificial neural networks (ANN), regular SVM, and wavelet preprocessed artific...

The emerging market of digital 3-D film productions in HD resolution leads to the need for high-quality equipment in the production chain. First, the images are treated in order to improve their pixel to pixel correspondence and reduce illumination differences. After that, stereo matching is addressed using different methods with emphasis on local ones like the sum of absolute distances and nor...

The paper describes a method for depth extraction from multiple, calibrated images. Emphasis lies on the integration of multiple views during the matching process. This process is guided by the relative confidence that the system has in the data coming from the different views. This weighing is fine-grained in that it is determined for every pixel at every iteration. Reliable information spread...

We have compared fronto-central and bifrontal montages using a new EEG monitor, the Aspect A-1000. The monitor uses bispectral analysis to derive an index of anaesthetic depth, the bispectral index (BIS). We compared reliability, impedance and BIS for each montage. ECG electrodes placed in a bifrontal montage were more reliable than silver dome electrodes in a fronto-central montage and both ty...

The information carried by a signal unavoidably decays when the signal is corrupted by random noise. This occurs when a noisy channel transmits a message as well as when a noisy component performs computation. We first study this signal decay in the context of communication and obtain a tight bound on the decay of the information carried by a signal as it crosses a noisy channel. We then use th...
