Non-linear & non-smooth is the important characteristics of sea clutter. Hilbert-Huang Transform is a new analysis method for nonlinear & non-smooth signals. When doing the Hilbert-Huang Transform to the radar signals, after the Empirical Mode Decomposition, the Trend Function and parts of Intrinsic Mode Functions are different between the sea clutter and target. By use of this characteristic,...
This Paper presents a novel method for the detection of moving object and shadow based on RGB color space and edge ratio. In the first step, we analyzed the different characteristics of object and shadow in RGB color space. In the second step, the likely object and shadow regions were detected in preliminary, according to the chromaticity distortion and brightness distortion of the pixel between current...
