Abstract

Abstract Effective analysis of complex imagery is a vital aspect of important domains such as intelligence image analysis. As technological developments lower the cost of gathering and storing imagery, the cost of searching through large image sets for important information has been growing substantially. This paper demonstrates the feasibility of using neurophysiological signals associated with early perceptual processing to identify critical information within large image sets efficiently. Brain signals called evoked response potentials, detected in conjunction with rapid serial presentation of images, show promise as a human computer interaction modality for screening high volumes of imagery accurately and efficiently
