用法例句

For the purpose of segmenting image without over-segmentation and without position errors of regional contours,a method for watershed segmentation is proposed based on viscous morphological gradient modification.

分水岭变换是一种有效的图像分割方法,但存在过分割现象,尽管应用预平滑处理可以减轻或消除过分割,但却容易使分割后的区域轮廓发生位置偏移,为此,文中首先对图像进行形态学梯度变换,然后运用粘性形态学运算对梯度图像进行地貌修正,在消除产生过分割的非规则局部极小值的同时,保持区域轮廓的位置不变,最后在梯度修正图像的基础上,运用标准分水岭变换实现图像分割。
