Small target motion detectors
WebOct 28, 2024 · The local contrast method (LCM) (Chen et al. 2014) is an algorithm inspired by the human visual system (HVS) and designed for the detection of small, dim targets. Traditionally LCM has been used on thermal infrared imagery where target responses stand out from the background more than in the visible spectrum. WebAug 31, 2024 · Distributed radar array brings several new forthcoming advantages in aerospace target detection and imaging. The two-dimensional distributed array avoids the imperfect motion compensation in coherent processing along slow time and can achieve single snapshot 3D imaging. Some difficulties exist in the 3D imaging processing. The …

WebDiscriminating targets moving against a cluttered background is a huge challenge, let alone detecting a target as small as one or a few pixels and tracking it in flight. In the insect's visual system, a class of specific neurons, called small target motion detectors (STMDs), have been identified as showing exquisite selectivity for small target motion. Some of the … WebApr 18, 2006 · Usually, the detection of small moving targets is followed by a pursuit in which both the target and the pursuer move. For example, male hoverflies engage in visually guided tracking of females or other males in flight ( Figure 1) 1, 6.

Surprisingly, the visual systems of insects have evolved to be highly efficient in detecting mates and tracking prey, even though targets occupy as small as a few degrees of their visual fields.
WebAs a source of inspiration, insects are quite apt at searching for mates and tracking prey, which always appear as small dim speckles in the visual field. The exquisite sensitivity of insects for small target motion, as revealed recently, is coming from a class of specific neurons called small target motion detectors (STMDs).
