Registration and fusion of infrared and millimeter wave images for concealed weapon detection

Detection and Tracking of Multiple Metallic Objects in Millimetre-Wave Images

“…More recently, some work on the detection and segmentation of metallic objects has been proposed (Haworth et al, 2004) for the QinetiQ sensor. Alternatively, image fusion (Varshney et al, 1999;Xue and Blum, 2003) has been employed on MMW/IR. While this work has produced visually appealing images for human operators, no work has been reported on automatic detection in fused MMW-IR images and it is not clear that there would be any benefit.…”

A new automated quality assessment algorithm for image fusion

“…These images could be obtained from different frames taken by a single camera or sensor, or from different sensors, possibly employing different modalities. Various fusion approaches have been developed in recent years [1][2][3][4][5], and a fundamental issue of image fusion is to evaluate the performance of a fusion scheme.…”

On multisensor image fusion performance limits from an estimation theory perspective

“…For the reader unfamiliar with image fusion, we give one example of using image fusion in the concealed weapon detection application discussed in [6][7][8] and [29]. Fig.…”

“…It is worth noting that image-level fusion, or image fusion, is closely related to signal-level fusion since an image can be considered a two-dimensional signal. In recent years, image fusion has been attracting a large amount of attention in a wide variety of applications such as concealed weapon detection [6][7][8], remote sensing [9][10][11], intelligent robots [12,13], 1566 [14,15], defect inspection [16,17], and military surveillance [18][19][20].…”
