A new statistical texture feature: direction measure
Xiaohan Yu, Baozong Yuan · Close-Range Photogrammetry Meets Machine Vision · 1990
A new texture feature, called Direction Measure(DM), is proposed in this paper, The new feature is based on the principle that in a homogeneous texture the gray values of pixels along any direction must change according to certain regularity( determined or stochastic); To determine such kind of regularity can get much information on the texture structure or statistical properties. The DM can also be easily extended to rotation-invariant features which can recognize the same texture no matter in what orientation it is pictured. The new rotation- invariant features are also very effective and are really rotation-invariant. Another advantage of the DM lies in that it can be easily computed and implemented by multiprocessors in a parallel way.
