基於最速下降曲線的特徵值法 -
You may discern by a certain fitful glare of the eye and sharp curve of the nose which manifest their descent from the ancient harpies.
你可以從他們那種閃閃發亮的目光和彎鉤的鼻子看得出來,他們就是古代哈比的後裔。 -
A developed simple m - s model for image segmentation in geometric active contour model is presented based on intra - region similar and inter - region dissimilar properties. the model constructs an energy ( cost ) function, which is made of intra - region variations and weighting squares of subtraction of region mean values. using gradient - descent methods, the energy function is minimized and we get a curve evolution equation that segments image
基於區域內一致性加權區域間差異性構造能量函數,利用最陡梯度法使能量函數最小化,提出了一種改進的簡化mumford - shah ( m - s )圖像分割模型,該模型利用區域內方差描述區域內一致性,區域間平均灰度值之差的平方描述區域間差異性,實驗結果表明,通過調節加權系數,該模型對弱邊界圖像分割具有較強的適應性。
