Embodiment Construction
[0038] The specific implementation of the method of the present invention will be further described below in conjunction with the accompanying drawings.
[0039] The feature selection method based on the memory multi-point cross-gravity search provided by the present invention is suitable for processing the hyperspectral remote sensing images in the Indian Pine area acquired by the AVIRIS (Airborne Visible Infrared Imaging Spectrometer) sensor. The spatial resolution and spectral resolution of the original AVIRIS data are 10m (meter) and 10nm (nanometer) respectively, and the spectral range covers 400-2400nm, with a total of 224 spectral segments. Since the values of 4 bands are all 0, they are filtered out. In addition, on the Indian Pine image, there are 20 bands, including bands [104-108], [150-163] and 220 whose values are easily affected by water absorption bands, and these bands are also filtered out in this case. Therefore, the IndianPine image used in this case us...
