ABSTRACT:
A scalar data processing method and apparatus for compressing scalar data defined on a two-dimensional surface and for reconstructing the two-dimensional scalar data based on the compressed data. Edge lines of the scalar data are detected, a domain is obtained on a horizontal line intersecting with the edge lines and between the edge lines, and a function is determined as an approximation of a Laplacian of the two-dimensional scalar data at each point in the cut domain. The two-dimensional scalar data is compressed by replacing the two-dimensional scalar data at every point with scalar data at the edge lines, scalar data for providing gradients of the two-dimensional scalar data on the edge lines, and the function determined above. The two-dimensional scalar data by interpolating the two-dimensional scalar data based on the scalar data is reconstructed at the edge lines, scalar data for providing gradients of the two-dimensional scalar data on the edge lines, and the above function.
