The system in this paper generates a ceiling map from video obtained by an upward camera of a moving indoor robot. The map is shared by robots for auto-localization. When the floor is not flat, automatically estimated location contains error. We compensate the error by utilizing video from a forward camera of the robot. In the system, a remote server estimates the location based on data transmi...

In this paper, we evaluate the impact of accurate 802.11 based wireless channel modeling on the efficiency of dynamic Forward Error Correction (FEC) schemes in Motion JPEG 2000 video streaming systems. We derive a compromise on the suitable trace length for practical estimation of Packet Error Rate (PER) at decoder side. We demonstrate the validity of the derived trade-off using a real JPEG 200...

In this paper, we present an integrated system for smart encoding in video surveillance. This system, developed within the European IST WCAM project, aims at defining an optimized JPEG 2000 codestream organization directly based on the semantic content of the video surveillance analysis module. The proposed system produces a fully compliant Motion JPEG 2000 stream that contains regions of inter...

In the next millennium, computer animation will be both the same as now and also very different. Animators will always have tools that allow specifying and controlling through manual interactive interfaces every nuance of shape, movement, and parameter settings. But whether for skilled animators or novices, the future of animation will present a fantastically expanded palette of possibilities: ...

Introducing a concept of real, as opposed to nominal, inequality of income or wealth suggests some historical reinterpretations, buttressed by a closer look at consumption by the rich. The purchasing powers of different income classes depend on how relative prices move. The influence of relative prices on real inequality was greater in the sixteenth through nineteenth centuries than in the twen...

The term "Ur-emotion" is proposed as a name for abstract structures, essences, or underlying structures of emotion that can be perceived across cultures and species. The “Ur-“ prefix is borrowed from the German on analogy to similar borrowings in textual criticism and musicology. Unlike the term “basic emotion,” the proposed term “Ur-emotion” does not suggest an actual occurring emotional state...
