BP4D: 4D Spontaneous Facial Expression Database

4D Spontaneous Facial Expression Database Background: Because posed and un-posed (aka “spontaneous”) 3D facial expressions differ along several dimensions including complexity and timing, well-annotated 3D video of un-posed facial behavior is needed. The BP4D dataset comprises videos of spontaneous facial expressions in a diverse...

BP4D+ Multimodal Spontaneous Emotion Database

Well-annotated, multimodal, multidimensional spontaneous emotion corpus of 140 participants. Background: In the last 10 years, research on facial expression analysis has shifted its focus from posed behavior to non-posed (i.e., spontaneous) behavior. This shift has increased the difficulty of such analyses, but also their ecological validity...

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

Heart rate estimation from face videos Background: 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 and can be used to estimate heart rate (HR). While considerable progress has been made in the last few years, still many issues remain...

Heart Rate Estimation from Face Videos

Usingaself-adaptive matrix heart rate etimation from face videos is improved. Background: 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...

Real Time Hand Tracking and Pointing for Human Interaction

A technology that provides an accurate hand pointing estimation system for human-computer interactions. Background: 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...

Real Time Eye Tracking for Human Computer Interaction

A technology that captures the direction the eyes point to while the subject is away from the camera for intuitive human-computer interfaces Background: 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...
