Directionality with the Structure Tensor

This demonstration shows the directional local features computed from the gradient structure tensor. The only parameter is the local neighborhood window which is here a Gaussian window of standard deviation σ. To get more information, consult the documentation. Other features are accessible using the ImageJ plugin: OrientationJ.
