Global and local search for tracking

The image of nano-bead is kind of simple: the sizes of the beads are similar and the color is just in gray level. The peak values are the positions of the beads. For next Thursday's demo, it is easy to implement with this algorithm: Global search the entire image and get the initial positions of the nano beads. For each bead, give it a trust region and search the peak value in this region (local search). Draw the marker square around the beads.
