Remote sensing images can widely used in many scientific research fields for its ability of detecting large area simultaneously and quickly. However, persistent cloud and haze region effect on their use. This paper used haze optimized transformation (HOT) transformation to remove haze region from CBERS remote sensing data. Band 1 and band 3 of CBERS image are selected to generate HOT image using linear...
Matched filtering method is successfully used in classification for hyperspectral image. However, it is hard to extract the low reflectance ground object due to atmospheric influence. In this paper, an improved unsupervised classification method was introduced. It can extract the low reflectance object such as vegetation in shadowed region and water from the hyperspectral image effectively. Firstly,...
Matched filtering (MF) methods are widely used to detect specific materials based on matches to library or image endmember spectra. This paper used decision tree to combine three MF methods to extract the dioritic porphyrite from the hyperspectral remote sensing image. The study areas located at the Pulang porphyry copper and gold deposits in southwest of China. Firstly, the image was calibrated to...
