Figure 6
Graph of changes in the criterion J for a sample pair of images L Tb (0) ( n + Δn,i + Δi ) and L Ta ( n,i ) and images after correction. The value looked for in the graph is the minimum for which the values of shifts in both axes (Δn, Δi) and the zoom which gives the smallest value are read. In this case, the graph refers to a constant zoom of the image L Tb (0) (0%) and for the example shown the following values were read from the graph: Δn = 9 and Δi = 4 pixels. In the left hand side of the image, there are the results obtained after shifting: images L Ta and L Tb *.
