惯性比 meaning in English

inertia ratio
ratio of inertia

After that , an integrated color histogram is built based on the subregion color histograms . this integrated color histogram overcomes the disadvantage of simple global color histogram . to digitally represent a color histogram an inertial moment ratio calculated from a color histogram graph is proposed as a new digital feature of the color histogram
通过比较各个区域颜色直方图的相似性匹配图像，可克服全局直方图的局限性，对颜色直方图的度量是其中一个关键技术，利用惯性比来从颜色直方图提取特征，能够保证简单明了地表达颜色直方图。
