In this paper, we consider the problem of quantifying changes in the perceived quality of audio by directly measuring the brainwave responses of human subjects using a highresolution electro-encephelogram (EEG). Specifically, human subjects are presented with audio whose quality varies with time while being monitored by a 128-channel EEG; some of the time,(More)
The human brain is a complex and dynamic system. This paper quantifies how it responds to change in video quality through changes in the distribution of feature vectors extracted from high-resolution electroencephalograph (EEG) signals. Specifically, subjects watch test video sequences with and without degradation while their brain response is recorded(More)
OBJECTIVE To assess the status of office laboratory residency education and training in family practice, internal medicine, obstetrics and gynecology, and pediatric residency programs. DESIGN A single mailed survey to 1299 residency programs from December 1992 to February 1993. PARTICIPANTS Primary care residency directors from 507 (39%) of 1299(More)
The ultimate goal of our research project is to quantify the human perception of video quality directly from brain responses. Specifically, subjects watch a set of video sequences whose qualities vary with time while their brain responses are monitored using a 128-channel electroencephalograph (EEG). We compare four potential sets of time-localized feature(More)
