| abstract |
The invention provides a method for extracting a Landsat-8 image breeding pond with a combined index and a contour indicator SLIC, including: image preprocessing, mainly including radiation calibration and atmospheric correction; Point connection forms a complete edge map, extracts closed contour targets and generates SLIC superpixels; automatically selects sea and land seed points to generate binary images of water targets; sequentially removes other interfering water targets other than aquaculture ponds, including removal of oceans, shallow tidal flats, and rivers , lakes, mountains or building shadows. The invention can effectively extract the coastal zone culture pond of the multispectral image under the medium resolution. |
