here. The target was still found, but an on-axis bright spot was identified as a correlation peak as well. … Figure 17. Correlation using zero difference as a binarization threshold in the joint transform plane. Figure 18 demonstrates the correlator's robust performance. Although the template and scene are taken from two different FLIR files, and the target within the scene is highly corrupted relative to…
