原始语种摘要: Abstract(#br)The scale-invariant feature transform (SIFT) is known as one of the most robust local invariant feature and is widely applied to image matching and classification. However, There is few studies on SIFT for hyperspectral image (HSI). Hyperspectral image (HSI) embraces the spectral information reflecting the material radiation property and the geometrical relationship of the objects. Thus, HSI provides much more information than gray and color image. Therefore, this paper puts forward a spatial-spectral SIFT for HSI matching and classification by using the geometric algebra as its mathematic tool. It extracts and describes the spatial-spectral SIFT feature in the spatial-spectral domain to exploit both the spectral and spatial information of HSI. Firstly, a spatial-spectral...
