Figure 2

Example of local slopes estimation. (a) shows the same function plotted for maximally overlapped blocks and in Figure 1; the straight lines spanning over 5 points centered around the diamond symbols at , , , and represent the local slopes evaluated by the 5-point derivative of (5). (b) shows the corresponding spectrum of local slopes.
