Accurate and fast identification of a person from a security point of view is a key procedure. The most common technique of person identification uses identity cards. In contrary to the common approach we focus our research on identification based on

In photo-realistic image synthesis the incoming light from the environment is particularly important. In this work we focus on capturing the incoming light in the form of the radiance map using a common mobile device. This involves the reconstruction

Nowadays digital cameras with both high resolution and the high dynamic range (HDR) can be considered as parallel multiple sensors producing multiple measurements at once. In this paper we describe a technique for processing the captured HDR data and

To acquire a certain level of photorealism in computer graphics, it is necessary to analyze, how the materials scatter the incident light. In this work, we propose the method to direct rendering of isotropic bidirectional reflectance function (BRDF)

This paper discusses the method to display the surfaces that exhibit sparkling and depth effects. Sparkling effects are usually caused by the metallic flakes diffused in the paint or coating. The novelty of the approach is to explicitly model the spa

In this article, we propose a methodology to measure the light reflectance of the material surface using a simple hardware set-up consisting of generally available mobile phones. The designed method incorporates two mobile phones to facilitate a time

The key quantity for expressing the directional optical effect of materials on the incident radiance is the bidirectional reflectance distribution function (BRDF). Our work is devoted to the BRDF spectral measurements, in order to render the syntheti

Measurement of the appearance of an object consists of a group of measurements to characterize the color and surface finish of the object. This group of measurements involves the spectral energy distribution of propagated light measured in terms of r
