MMSE-HR dataset (Multimodal Spontaneous Expression-Heart Rate dataset)

Recent studies in computer vision have shown that, while practically invisible to a human observer, skin color changes due to blood flow can be captured on the face and can be used to estimate heart rate (HR). This strategy dynamically selects face regions useful for robust HR estimation. Our approach, inspired by recent advances in matrix completion...

4D Spontaneous Facial Expression Database

3D video database of spontaneous facial expressions of a diverse group of young adults. Well-validated inductions were used to elicit expressions of emotion and paralinguistic communication. Frame-level ground-truth for facial actions was obtained using the Facial Action Coding System. The work promotes the exploration of 3D spatiotemporal features...

Heart Rate Estimation from Face Videos

Recent studies in computer vision have shown that, while practically invisible to a human observer, skin color changes due to blood flow can be captured on face videos and be used to estimate the heart rate (HR). These subtle changes encompass both color and motion, and they are induced by the internal functioning of the heart. However, state-of-the-art...

Real Time Hand Tracking and Pointing for Human Interaction

Hand gesture is an efficient means for humans interacting with computers. Pointing gesture can resolve ambiguities derived from the verbal communication, thus opening up the possibility of humans interacting or communicating intuitively with computers or robots by indicating objects or pointed locations either in the three dimensional (3D) space or...

Real Time Eye Tracking for Human Computer Interaction

The ideal human-computer interaction system should function robustly with as few constraints as those found in human-to-human interaction. One of the most effective means of interaction is through the behavior of the eye. Specifically, knowledge of the viewing direction and thus the area of regard offers insight into the user's intention and mental...
