Verfahren und Einrichtung zur Verarbeitung von skalaren Daten |
摘要 |
<p>The invention serves to compress scalar data defined on a two-dimensional surface and to reconstruct the two-dimensional scalar data from the compressed data. It involves detecting edge lines (11-1, 11-2) of the scalar data (o (i, j)), cutting a domain (12) on a horizontal line (17) intersecting with the edge lines (11-1, 11-2) and between the edge lines; determining a function (f (i)) as an approximation of a Laplacian of the two-dimensional scalar data at each point in the cut domain; compressing the two-dimensional scalar data ( o(i, j)) by replacing the two-dimesional scalar data at every point with scalar data at the edge lines, (11-1, 11-2), scalar data for providing gradients of the two-dimensional scalar data on the edge lines, and the function determined above; and for reconstructing the two-dimensional scalar data based on the scalar data at the edge lines, scalar data for providing gradients of the two-dimensional scalar data on the edge lines, and the above function (f (i)). <IMAGE></p> |
