A method for generating time independent images of moving objects the image information being related to properties of the moving object represented by parameters

摘要

A method for generating time independent images of moving objects comprising the following steps:providing a sequence of digital images of the movin g part of an object;transforming image information of said sequence into a series of space -time images comprised of pixels or groups of pixels on a series of adjacent line -segments, said line-segments being positioned in such a way as to cross the said mo ving part of said object and being distributed in such a way as to completely cover said moving part of the said object;aligning said space -time images of each of said line -segments related to different images of said sequence in order to compensate for m otion of said moving part of said object along said line -segments by shifting said images of said sequence taken at different times along a given line -segment for a distance corresponding to the displacement of said moving part of said object;defining an evaluation function having at least one parameter and calculating for each pixel or group of pixels the value of the said parameter for best fitting said evaluation function with a curve representing the values of said pixel or group of pixels obtained fro m said aligned space-time images; andconstructing a parametric image by defining a pixel appearance scale univocally correlated to said at least one parameter.
