惯性矩比 meaning in English

inertia ratio
ratio of moment of inertia

Some new features such as ratio of centripetal moment , ratio of eccentric moment and ratio of inertial moment are introduced in this dissertation . these features have the properties of scale - invariance - , rotation - invariance and translation - invariance , and can be used well in depicting the linearized outline object
本文提出向心矩比、偏心矩比、惯性矩比概念，对线性化后的轮廓应用本文方法，既能较好地描述图像目标，又具有旋转、平移和尺度不变性。
This dissertation deals with the content - based image retrieval ( cbir ) theory and technique ; some new features and tools for more concisely and discriminatingly charactering the content of an image are proposed , such as region - based color histogram , grey - primitive co - occurrence matrix , ratio of centripetal moment , ratio of eccentric moment and ratio of inertial moment . a new modified genetic algorithm is also described in this dissertation , which can upgrade the performance of standard genetic algorithm ( sga ) while used in image segmentation
本文以图像数据库检索为主线，讨论了基于视觉内容的图像检索方法，提出包括基于区域颜色直方图、灰度?基元共生矩阵及向心矩比、偏心矩比、惯性矩比的特征描述方式；对遗传算法存在的早熟、收敛到最优解慢等问题提出了解决方法，并将改进遗传算法应用到图像分割中，编制了相应程序。
