Describing Texture Directions with Von Mises Distributions
Costantino Grana, Daniele Borghesani, Rita Cucchiara · 2008
In this work we describe a new approach for texture characterization. Starting from the autocorrelation matrix an elegant description through a mixture of Von Mises distributions is proposed. A compact 6 valued descriptor is produced for each block and served as input to an SVM classifier. Tests are carried out on high resolution illuminated manuscripts images.
