WebApr 27, 2024 · Small target motion detection within complex natural environments is an extremely challenging task for autonomous robots. 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. 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 …

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. WebInfrared dim and small target detection is widely used in military and civil fields. Traditional methods in that application rely on the local contrast between the target and background for single-frame detection. On the other hand, those algorithms depend on the motion model with fixed parameters for multi-frame association. For the great similarity of gray value …
