Advanced methodology for frequency description of biomechanical systems

摘要

After basic frequency-based analysis and segmentation for high speed videosequences containing motion information, it is necessary to remove some of the motion artifacts distorting the results for accurate analysis. In the paper we are describing construction of amplitude and phase maps based on FFT and projecting 3D image information (videosequence) to relevant 2D arrays. Synthesis of these maps with basical frequency ones brings more accurate information about regions with useful information (regions with normal motion of objects). Last part of the paper offers solutions on the basis of separate region morphology.
