Finally, the modification of water-edges is fulfilled based on the coastline computation model, thereby the coastal line is completely extracted.
最后依据海岸线计算公式对水边线进行了岸线修正，完成了对海岸线的提取。
In the gradient image, only the summits of main peaks corresponding to real edges are extracted, where as the little sharp maxima in edges' vicinity caused by noises would not be chosen.
并且它仅选取出梯度图中相应于边缘的极大值点，在其附近由噪声引起的小的极大值点不会被选取出。
Liking what I saw, I extracted the image properly, this time using the pen tool, as I wanted to preserve the nicely curved edges.
喜欢我所看到的，我提取的形象，妥善，这个时候用钢笔工具，正如我要保存好，弯曲的优势。
The extracted object has rough edges that are often tinted with the color of the previous background.
提取对象有粗糙的优势，这往往是有色与颜色前的背景。
Secondly, the binary SAR image is processed by using morphological operations to extract edges of the object and remove smaller areas. Then lines are extracted by Hough transform.
其次，利用形态学运算，对已除去噪声的二值SAR图像进行边缘提取，并对边缘图像进行形态学区域开运算，以去除较小的区域。
We proposed figure continuity constraints by applying disparity smoothness constraint in the edges extracted by our algorithm, which can eliminate the error matching;
将视差光滑性约束应用于边缘特征上，提出了边缘连续性约束，这一约束能去除误匹配点；
