An algorithm for automatic recognition of overwater bridge target based on “joint feather and knowledge rule-based” is presented for the problem concerning automatic recognition of overwater bridge target in optical remote sensing images. Firstly, based on knowledge feathers of overwater bridge target, waters in an optical remote sensing image are extracted to narrow down bridge detection range. After...
In view of the problem of non-target interference and misjudgment in road extraction from remote sensing images, a new method of road extraction based on curvelet fusion is presented. Firstly spectral similarity matrix is calculated in multispectral images. Then the panchromatic image and the spectral similarity matrix are fused by using curvelet transform. The result is processed with cross-correlation...
