The representative features, which are also invariant to the translation, scaling and rotation, should be select for improving the precision and velocity.
为了提高分类处理的速度和精度，需选择具有代表性的特征，而且这些特征应具有比例、旋转、平移不变性。
This representation is invariant to the translation, rotation, and scaling change of the object.
这种表示是客体平移、旋转和相似变化的不变量。
It's a key problem to search for affine invariant with respect to translation, scaling, rotation and skewing in multi-resolution analysis.
寻找相对于平移、尺度、旋转、扭曲不变的仿射不变量是现今多尺度分析在模式识别中应用的关键性问题。
