concavity

基本解釋

It is evident that curvature of doming whether on the crest (convexity) or on the flanks (concavity) have no major effect on fracture densities.
很明顯，穹窿的曲率在波峰（突起）或兩翼（凹陷）對斷裂密度都沒有很大影響。
Importing the concavity map into the displacement channel, I applied the map as a displacement at a level of 0.01 to the model.

The results showed that a concavity in the surface could be clearly observed at the center of starches.
結(jié)果表明：微波淀粉顆粒表面出現(xiàn)凹坑，降低了膨脹度和溶解度、凍溶穩(wěn)定性。

His memory was able to adhere to her smoothness, to her rough parts, to her every swelling and concavity, but only in a way that was like an ache—like a hunger feeding upon itself.

All confines of gray scale are segmented into some parts, and multiple threshold is derived through in each part histogram of gradient, concavity analysis of histogram, moment and entropy of histogram. The multiple threshold image segmentation is achieved.
在基于閾值選取的圖像分割方法中,本文改進了傳統(tǒng)的迭代閾值法和基于梯度、凹度分析、矩、熵的單閾值分割方法,將灰度范圍進行了劃分,并根據(jù)各灰度區(qū)間的梯度直方圖、直方圖的凹度分析,直方圖的矩、熵得到多個閾值,實現(xiàn)了圖像的多區(qū)域分割。
