cephalometry is an important branch of anthropology in which the dimensions of head and face can be determined. these dimensions are used to show indexes for studying brain growth and formation of all types of head and face. indexes are vary from 65 to 95 for head and 65 to105 for face, which are used to determine 4 international anatomic types of head and 5 international anatomic types of face...

Analyzing people behaviors in smart environment using multimodal sensors requires to answer a set of typical questions: who are the people, where are they, what activities are they doing, when, with whom are they interacting, and how. In this view, locating people or their faces and characterizing them (e.g. extracting their body or head orientation) allows to address the first two questions (w...

Natural head motion is important to realistic facial animation and engaging human-computer interactions. In this paper, we present a novel data-driven approach to synthesize appropriate head motion by sampling from trained Hidden Markov Models (HMMs). First, while an actress recited a corpus specifically designed to elicit various emotions, her 3D head motion was captured and further processed ...

Active sampling of touch and smell involves coordinated movements first observed in the rat half a century ago. A new study has unveiled the elegant choreography of this facial and head motion during tactile and olfactory exploration.

This paper proposes a sequential importance sampling (SIS) particle filtering framework to track the human with overcoming the warping and low resolution. We utilize a foreground-based importance sampling mechanism for efficiently converge to the target distribution. We construct a tracking system with the fusion image likelihood, even the human raises the head. Furthermore, the two-space integ...

Background: Venipuncture is one of the most painful and common interventions in Neonatal ward. A preterm infant can not cope long-lasting physiologic stresses; therefore, the pain caused by blood sampling may change the infant’s physiologic responses to the stress. This present study aim is to investigated and compare physiologic changes (pulse rate and oxygen saturation) in two sites of blood ...

In order to achieve highly accurate 3D audio spatialization, an intended listener must undergo measurements in a specialized instrumentation system to obtain “individual” Head-Related Impulse Responses (HRIRs). Our goal is to create a customizable sound spatialization system that would not require complex individual measurements. Our approach is based on the reliable decomposition of measured H...

A key component in understanding the ecological role of marine mammal predators is to identify how and where they capture prey in time and space. Satellite and archival tags on pinnipeds generally only provide diving and position information, and foraging is often inferred to take place in particular shaped dives or when the animal remains in an area for an extended interval. However, fast move...
