Abstract: The present invention relates to a system and method for reconstruction of temporal wavefront changes for use in an optical system comprising: measuring the distribution function of the light intensity, e.g. the two-dimensional distribution function of the light intensity, in at least two different images taken at different times, wherein said images are taken in at least one optical plane, e.g. the same optical plane, of the optical system.

Abstract: The invention relates to a computer-implemented method for detecting barcodes in a digital image represented as a two-dimensional digital image array comprising: applying a filter to the image array, computing a discrete Radon transformation of the filtered image array, wherein the discrete Radon Transformation is computed for a plurality of discrete lines across the filtered image array, wherein for each given discrete line with a given slope the discrete Radon transformation is computed for a number of different displacements of the given discrete line, wherein said number of displacements is less than two times a dimension of the image array, detecting in the output of the discrete Radon transformation of the filtered image array the vertex points of a pattern, and converting the detected vertex points back to discrete lines in the image array for constraining the location of a barcode present in the digital image.
