| titleOfInvention | A kind of high-resolution remote sensing image Clean water withdraw method based on multiple features combining processing |
| abstract | The present invention relates to a kind of high-resolution remote sensing image Clean water withdraw methods based on multiple features combining processing.Radiation calibration is carried out to remote sensing image first, obtains the apparent amount of radiation of atural object, to exclude most non-aqueous volumetric pixel by carrying out Threshold segmentation to pixel length characteristic；Then the NDWI feature of the water body pixel to be selected retained to above-mentioned steps carries out Threshold segmentation, obtains water body object to be selected；Threshold segmentation is carried out to the NDWI feature of the pixel of small area object to be selected covering again, further excludes the background pixel mixed；The edge optimization that the mode of last using area growth carries out water body obtains final water body object exposure mask.The present invention has used partial structurtes length characteristic in Clean water withdraw, embodies the characteristic distributions of water body, and inhibits the interference of most of shade, and the mode for avoiding Direct Classification, which merges, is unable to fully the problem of embodying different characteristic feature caused by various features；Automatic Clean water withdraw, and the speed of service is fast. |
