Block diagram of image processing steps to synthesize an LDM. Laser-exposed frames were extracted from the video recorded during a simulation session. Each laser-exposed frame was binarized to clearly detect the laser spot, then its centroid position was computed. The LDM was reconstructed by overlaying the template image of the laser window to each centroid position of the detected laser spot.
