The proposed approach removes the subjective decision on the choice of drainage area threshold, and improves exactness of extracting geomorphic parameters.
研究方法排除了选取集水面积阈值时的主观性，提高了提取流域地貌参数的精度。
Finally, the area threshold is proposed to remove the wrong similar blocks, and the mathematical morphology operations are performed to localize the forgery part.
最后，利用区域面积阈值去除错误的相似块对，并结合数学形态学定位篡改区域。
Scientists use "hole" as a metaphor for the area in which ozone concentrations drop below the historical threshold of 220 Dobson Units.
