Evaluating Subpixel Target Detection Algorithms in Hyperspectral Imagery

Table 6

RIT results for the actual detection of V1 in RIT test image are shown in the first two lines. The percentage of implanted target was 0.75%. The GLRT and ACE algorithms were calculated as presented in the text. The size of the background was calculated for 3 × 3, 5 × 5 and 7 × 7 frames, excluding the center pixel. The “Only” 7 × 7 and 5 × 5 algorithms only used the outer ring of the window. The third and fourth lines represent the same results normalized by dividing by the values obtained by the 3 × 3 filter.
