integral invariant meaning in English

积分不变量
积分不变式

Absolute integral invariant

Thus , in this paper invariant features for image retrieval are investigated . we have research of many invariant features and two new methods are proposed to extract rst ( rotation scaling and translation ) invariant features by combining the integral invariant and the scale invariant keypoints extractor technique
本文研究了基于不变特征进行图像检索的算法,并结合对几何变换群的积分不变量构造原理和尺度不变特征点的提取原理,提出了两种新的旋转、平移和尺度不变特征(即rst不变特征)提取方法,并把这些特征应用于图像检索中。
