Biological Subtle Motion Magnification Based on 3D Wavelet Transform

Abstract

This paper presents an amplification algorithm of subtle motion which reveals important aspects of the world. Our analysis is based on spatial and temporal projection of decomposition of the viewpoint video by using 3D wavelet transform, which is used to estimate the optimal scale and threshold function in order to extract the interested region. We discuss parameters of effect and estimate the threshold function by employing integral energy and maximum values of pixels. The results of the subtle motion magnification by using the optimal scale and threshold function have a good effect
