30.6 Experiments for Concealed Target Detection

Two HYDICE datasets to be used in the experiments were two different image scenes taken in Maryland in August 1995 using 210 bands with spectral coverage 0.4–2.5 μm of resolution 10 nm and GSD approximately 0.78 m. Figure 30.6 shows an image scene with size of pixel vectors. Three vehicles of the same type are parked underneath the trees on the left edge and aligned vertically and circled by V1, V2, and V3 from bottom to top. Except V1, which is partially revealed, the other two vehicles V2 and V3 are completely concealed.

In this experiment, BBOPC used a two-layer pyramid to reduce the image size and generated seven bands (band numbers: 16, 41, 53, 57, 63, 83, and 96) with for band ratio transformation, which resulted in band-ratioed images obtained by (30.7). It was then followed by ATGP where 12 target signatures were detected and generated and each target signature was classified in an individual image. It should be noted that many of the targets detected were background signatures such as grass, ...
