WebApr 13, 2024 · Target detection in side-scan sonar images plays a significant role in ocean engineering. However, the target images are usually severely interfered by the complex … 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 …
WebJan 1, 2016 · Sea clutter refers to the signals returned from the wavy and turbulent rough sea surface. The radar returns from small targets, like submarine periscope or small boats, will be obscured by the sea clutter which makes the straightforward detection of targets, with small radar cross section, a difficult task.
