In this article, the authors propose a novel method of video magnification based on separation of the chromophore component. A video magnification method, Eulerian video magnification, was originally proposed by Wu et al. The method is effective in amplifying slight changes of facial color and can visualize the blood flow in the human face effectively. However, the conventional method was evaluated under stable conditions of illumination. It is necessary to enhance its robustness against environmental change for practical use. The proposed method amplifies the variation of the chromophore component which is separated from the shading component. The authors confirm that the proposed method can visualize the blood flow in the human face without artifacts caused by shading change. They also apply the video magnification framework to a tongue movie as preliminary work for medical application and confirm its effectiveness in visualizing the blood pulse and avoiding any clear artifacts.

More about this publication?
  • The Journal of Imaging Science and Technology (JIST) is dedicated to the advancement of imaging science knowledge, the practical applications of such knowledge, and how imaging science relates to other fields of study. The pages of this journal are open to reports of new theoretical or experimental results, and to comprehensive reviews. Only original manuscripts that have not been previously published, nor currently submitted for publication elsewhere, should be submitted.

    IS&T's JIST-first publication option allows authors wishing to present their work at conferences, but have a journal citation for their paper, to submit a paper to JIST that follows the same rigorous peer-review vetting and publication process as traditional JIST articles, but with the benefit of a condensed time-to-publication time frame and guaranteed conference presentation slot.

    Please note: For purposes of its Digital Library content, IS&T defines Open Access as papers that will be downloadable in their entirety for free in perpetuity. Copyright restrictions on papers vary; see individual paper for details.
