14.4 Synthetic Image-Based Computer Simulations

To evaluate performance of WAC-LSMA, a synthetic image similar to Figure 13.1 is simulated in Figure 14.1, where an area marked by “A” was used to simulate the image background.

Figure 14.1 A HYDICE image scene with background signature marked by A.

This synthetic image scene to be simulated has size of pixel vectors and 20 panels with various sizes arranged in a matrix and located at the center of the scene, as shown in Figure 14.2(a).

Figure 14.2 A synthetic image with 20 implanted panels.

The five panel signatures in Figure 1.16 are used to simulate these 20 panels. For row i, the panel signature p_i was used to simulate four panels with a -pixel panel, {,,,} in the first column, a -pixel panel, {,} in the second column, a one-pixel panel, ...
