Local difference transform is invariant against any monotonictransformation of the gray scale.
局部差分变换具有灰度线性不变性，可消除光照变化对纹理分析的影响。

Summarize: a monotonictransformation of a utility function is a utility function that represents the same preferences as the original utility function.
总结：单调变换前后的效用函数的偏好相同。 总结：单调变换前后的效用函数的偏好相同。
