We propose a new detector which adopts the visibility graph algorithm... WebSep 9, 2024 · It is challenging to detect small-floating object in the sea clutter for a surface radar. In this paper, we have observed that the backscatters from the target brake the continuity of the underlying motion of the sea surface in the time-Doppler spectra (TDS) images. Following this visual clue, we exploit the local binary pattern (LBP) to measure the …
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 … WebThe method according to the invention detects small target on the sea with the difference. Furthermore the method does not require presupposing a sea clutter statistical model, and is not easily interfered by the sea peak. The application result of measured data also indicates that the method can effectively detect the small target on the sea.
