We present a new application of digital holography for phase-contrast imaging and optical metrology. This holographic technique uses CCD camera recording Fresnel off-axis hologram numerical method reconstruction. The simultaneously provides an amplitude-contrast image quantitative image. An to surface profilometry is presented shows excellent agreement with contact-stylus probe measurements.
We describe the development of a rapid, noncontact imaging method, modulated (MI), for quantitative, wide-field characterization optical absorption and scattering properties turbid media. MI utilizes principles frequency-domain sampling model-based analysis spatial modulation transfer function (s-MTF). present compare analytic diffusion probabilistic Monte Carlo models diffuse reflectance in frequency domain. Next, we perform measurements on tissue-simulating phantoms exhibiting wide range l...
Local and superficial near-infrared (NIR) optical-property characterization of turbid biological tissues can be achieved by measurement spatially resolved diffuse reflectance at small source-detector separations (<1.4 mm). However, in these conditions the inverse problem, i.e., calculation localized absorption reduced scattering coefficients, is necessarily sensitive to phase function. This effect minimized if a new parameter function gamma, which depends on first second moments function,...

A technique for measuring broadband near-infrared absorption spectra of turbid media that uses a combination frequency-domain (FD) and steady-state (SS) reflectance methods is presented. Most the wavelength coverage provided by white-light SS measurement, whereas FD data are acquired at few selected wavelengths. Coefficients (μa) reduced scattering (μs′) derived from used to calibrate intensity measurements estimate μs′ all wavelengths in spectral window interest. After these steps...

The spatially resolved reflectance of turbid media is studied at short source–detector separations (approximately one transport mean free path) with Monte Carlo simulations. For such distances we found that the first and second moments phase function play a significant role in curve, whereas effect higher-order weak. Second-order similarity relations are tested efficient reducing number relevant parameters necessary to predict reflectance. Indeed, only four following necessary: refractive...
Machine learning is one of the most important and successful techniques in contemporary computer science. It involves statistical inference models (such as classifiers) from data. often conceived a very impersonal way, with algorithms working autonomously on passively collected However, this viewpoint hides considerable human work tuning algorithms, gathering data, even deciding what should be modeled first place. Examining machine human-centered perspective includes explicitly recognising...

This article presents a gesture recognition/adaptation system for human--computer interaction applications that goes beyond activity classification and that, as complement to labeling, characterizes the movement execution. We describe template-based recognition method simultaneously aligns input templates using Sequential Monte Carlo inference technique. Contrary standard methods based on dynamic programming, such Dynamic Time Warping, algorithm has an adaptation process tracks variation in...
In this paper, we explore the use of movement qualities as interaction modality. The notion is widely used in dance practice and can be understood how performed, independently its specific trajectory space. We implemented our approach context an artistic installation called A light touch. This invites participant to interact with a moving spot reacting hand qualities. conducted user experiment that showed such based on tends enhance experience favouring explorative expressive usage.
This article reports on an interdisciplinary research project movement sonification for sensori-motor learning. First, we describe different fields which have contributed to sonification, from music technology including gesture-controlled sound synthesis, sonic interaction design, learning with auditory-feedback. In particular, propose distinguish between sound-oriented tasks and movement-oriented in experiment involving interactive feedback. We several questions recently published results...

Absorption (mu(a)) and reduced scattering (mu(s)') spectra of turbid media were quantified with a noncontact imaging approach based on Fourier-transform interferometric system (FTIIS). The FTIIS was used to collect hyperspectral images the steady-state diffuse reflectance from media. Spatially resolved data Monte Carlo simulations fitted recorded quantify mu(a) mu(s)' in 550-850-nm region. A simple effective calibration introduced account for instrument response. With that close far source...
We investigated gesture description of sound stimuli performed during a listening task. Our hypothesis is that the strategies in gestural responses depend on level identification source and specifically action causing sound. To validate our hypothesis, we conducted two experiments. In first experiment, built corpora sounds. The corpus contains sounds with identifiable causal actions. second for which no actions could be identified. These properties were validated through test. participants...
Human movement has historically been approached as a functional component of interaction within human computer interaction. Yet is not only functional, it also highly expressive. In our research, we explore how expertise articulated in Laban Movement Analysis (LMA) can contribute to the design computational models movement's expressive qualities defined framework Efforts. We include experts LMA process, order select set suitable multimodal sensors well compute features that closely correlate...
Abstract The effects of music on bodily movement and feelings, such as when people are dancing or engaged in physical activity, well-documented—people may move response to the sound cues, feel powerful, less tired. How sounds movements relate create effects? Here we deconstruct problem investigate how different auditory features affect people’s body-representation feelings even paired with same movement. In three experiments, participants executed a simple arm raise synchronised changing...
