A new set of multiscale texture features based on B-spline image approximation

We propose a set of multiscale features for texture description. Image smoothing at multiple scales using the fast smoothing B-spline transform is performed and a number of features, such as the local area, the normal vector dispersion and the gradient orientation, are computed from each scale. Classification experiments with natural textures and comparison with other texture description methods prove the capabilities of the proposed features. Being effective even for small observation windows, these features are suitable for high-resolution texture segmentation
