Visual tracking for multimodal human computer interaction

User, Gesture and Robot Behaviour Adaptation for Human-Robot Interaction

“…al. [Yang, 1998] have implemented a camera-based face and facial features (eyes, lips and nostrils) tracker system. The system can also estimate user gaze direction and head poses.…”

Face and Gesture Recognition for Human-Robot Interaction

“…Recently, many researchers are combining multiple features for face localization and detection and those are more robust than single feature based approaches. Yang and Ahuja [Yang, 1998] proposed a face detection method based on color, structure and geometry.…”

Real-Time Vision Based Mouth Tracking and Parameterization for a Humanoid Imitation Task

“…In order to alleviate the influence of ambient lighting on the sample class data, chromatic color transformation is adopted for color representation (Chiang et al, 2003;Yang et al, 1998). It was pointed out (Yang et al, 1998) that human skin colors are less variant in the chromatic color space than the RGB color space.…”

“…It was pointed out (Yang et al, 1998) that human skin colors are less variant in the chromatic color space than the RGB color space. Although in general the skin-color distribution of each individual may be modeled by a multivariate normal distribution, the parameters of the distribution for different people and different lighting conditions are significantly different.…”
