Embodiment Construction
[0013] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0014] The sea and land template automatic segmentation method based on scan line detection of the present invention comprises the following steps (such as figure 1 shown in the first dotted box):
[0015] 1) Input the high-resolution visible light port remote sensing image to be detected (such as figure 2 Shown), carry out resampling processing according to the resampling processing method related to the pixel area in the prior art;
[0016] 2) For the port remote sensing image after resampling, use the sea surface region seed point detection method based on the scan line to detect the sea surface region seed point, the process is as follows (such as image 3 shown):
[0017] ①Scan the resampled port remote sensing image progressively from top to bottom, first scan the first line;
[0018] ② Determine the number of invalid pixels in the scanned ...
