An Experience Oriented Video Digesting Method Using Heart Activity and Its Applicable Video Types

摘要

An experience oriented, physiology based video digesting method is proposed, and its applicable video types are experimentally examined. The proposed method extracts shots that have made audiences most attentive by analysing two attention measures obtained from heart activity while watching. To assess its applicable types, three original videos that convey distinctive emotional quantity were prepared, and three test digests-shots selected randomly, subjectively and by the proposed method-were generated from each original. Then, the proposed method was evaluated not only by its precisions against the subjective selection, but also by digest viewing experience from subjective scores and a psychophysiological measure. The experiment showed that the proposed method was promising for those with arousing, event-driven contents. It was also suggested that use of multiple evaluation measures is important to exhibit applicability of a digesting method.
