Describes a method to compensate for spatial distortion in quasiperiodic structures allowing a noise reduction by averaging. The successive steps of processing are preprocessing by local normalization, the detection of control points by cross-correlation, the estimation and compensation of the warping function using bidimensional polynomials, and finally noise reduction by filtering of accumulation. This method is applied to the improvement of high resolution images of thin sections of muscle fibers obtained by electron microscopy.
