Combining audiovisual sequences from different cameras requires precise alignment in time. Current synchronization techniques involve using geometrical properties such as camera positions and object features. In this paper, we present a synchronization method based on detecting flashes present in the video content. Such flashes, generated by still cameras,… (More)
We present a method to synchronize popular music with its lyrics at the stanza level. First we apply an algorithm to segment audio content into harmonically similar and/or contrasting progressions, i.e. the stanzas. We map the stanzas found to a sequence of labels, where stanzas with a similar progression are mapped to the same label. The lyrics are… (More)
We present results from two experiments designed to explore temporal properties of human color vision relevant to dynamic lighting applications. Sensitivity for smoothness perception of linear temporal transitions and flicker visibility was tested. Stimuli in the first experiment were linear color transitions, varying in either lightness, chroma or hue,… (More)
Preface I come from Poland. Several months ago I came to Eindhoven to do my studies. I followed master programme Human-Technology Interaction at the Eindhoven University of Technology. In the last phase of this study I joined Philips Research, the group of Visual Experiences, where I completed my graduation project. This report is a result of this project.… (More)
Human observers are sensitive to light properties such as the intensity, direction and diffuseness. We study how well they are able to estimate the light field (the structure of the net flux transport) in rooms, by empirical measurement and comparison of the physical and visual light fields. We made regularized measurements of the physical light field in a… (More)
This paper looks at attributes helpful for a definition of involvement, because the authors believe that involvement is one of the key cognitive mediating factors between content and viewing experience. In the end, it should lead to an operational definition, and a valid and reliable measurement tool.
