Figure 3

Pattern recognition algorithm sketch. The seed recognition part is shown in the left canvas. Once the deposited energy in a pixel is found to be above a certain threshold, a maximum search routine is implemented in a 6×6 area, in order to find the cluster seed. The shape recognition part, shown in the right canvas, starts from the recognized seed for a larger area, equal to 9×9 pixels. The deposited energy of each pixel in this area is summed up to calculate the cluster energy.
