FIGURE 2. The experiment algorithm.
The algorithm used for the sequential quantized recalculation takes
place since each of the components of the gradient surface of the color
difference increment with respect to the unprinted substrate changes
sign at least only once. In other words, the surface of color
differences to the substrate color has no local maxima or minima.
For each point of the isoline, the sum of the color differences to the
point corresponding to the initial (for instance, unprinted paper) and
target points (for instance, full dye Cyan) is computed. Among all these
sums corresponding to one p , the lowest value has been found. The
recipe (m , n ) corresponding to this minimal sum at the
isoline defines the recipe of the geodesic crossing this isoline. The
complete set of points found in this way forms the desired geodesic.
This line provides the shortest path from the paper point to the point
of complete double overlap. This is the major result of the proposed
algorithm.
