摘要： PROBLEM TO BE SOLVED: To provide parametric spatio-temporal alignment between image sequences. SOLUTION: A method for aligning a plurality of image sequences has a process for calculating space-time coordinate transformation which includes: a process for calculating an error in luminance change between both the image sequences in order to align one point in a space-time volume corresponding to one of the image sequences to one point in a space-time volume corresponding to another one of the image sequences; and a process for estimating the space-time coordinate transformation, based on the error in the luminance change. In the calculation process, the error in the luminance change at each space-time point is minimized by adding a product, which is obtained by multiplying an unknown spatial-temporal deviation between one image sequence and another image sequence in each space-time point by the gradient of luminance in each space-time point, to a difference in luminance between each space-time point in another image sequence and a space-time point corresponding to one image sequence. In the estimation process, the space-time coordinate transformation for restricting the whole unknown spatial-temporal deviation in each space-time point is estimated. COPYRIGHT: (C)2009,JPO&INPIT
