SUN Hui, SUN Kai, HOU Qing-Yu. The Adaptive Small Target Detection Based on Principal Component Analyzation in Feature Space[J]. 2011, 16(3): 62-67.DOI:
To detect infrared small target in non-stationary complex background
at first
the intensity of target
distribution gradient of target and step characteristic between target and background are considered
in process of feature selection.The three-dimensional features are extracted
which contain contrast between each local area pixel and its surrounding background
the local standard deviation of pixel and the modulus of high frequency components of wavelet transform at position of pixel.Regarding the process o...
