The photon map technique for global illumination does not specifically address animated scenes. In particular, prior work has not considered the problem of temporal sampling (motion blur) while using the photon map. In this paper we examine several approaches for simulating motion blur with the photon map. In particular we show that a distribution of photons in time combined with the standard p...

Quadratically parametrized smooth maps from one complex projective space to another are constructed as projections of the Segre map of the complexification. A classification theorem relates equivalence classes of projections to congruence classes of matrix pencils. Maps from the 2-sphere to the complex projective plane, which generalize stereographic projection, and immersions of the complex pr...

In a series of papers (??) we studied in detail the statistical properties of an interpolation technique widely used in astronomy. In particular, we considered the average interpolated map and its covariance under the hypotheses that the map is obtained by smoothing unbiased measurements of an unknown field, and that the measurements are uniformly distributed on the sky. In this paper we genera...

Approximation orders of shift-invariant subspaces of L p (IR d), 2 p 1, generated by the shifts of one compactly supported function are considered. In that course, explicit approximation maps are constructed. The approach avoids quasi-interpolation and applies to stationary and non-stationary reenements. The general results are specialized to box spline spaces, to obtain new results on their ap...

Detection and monitoring of nuclear accidents is of great importance. Many European countries have installed gamma dose rate monitoring networks to perform this task. Interpretation of the data would greatly benefit from real-time automatically generated maps with interpolated values based on the monitoring network. In this paper we present a first step toward a real-time automatic mapping syst...

In information transmission such as speech information, higher security and confidentiality are specially required. Therefore, data encryption is a pre-requisite for secure communication system to protect from unauthorized access. A new algorithm introduced in this paper. It depends on the quantum chaotic map k-means clustering, which employed keys generation. Also, two stages of scrambling wer...

Abstract Commonly used haptic interaction techniques are typically limited to touching solid glass displays or vibrations. Although there are more complex experimental haptic interfaces, their real application is often unclear. Our prototype of tangible heat map for visually imp...
