Planar Orientation from Blur Gradients in a Single Image
We present a focus-based method to recover the orientation of a textured planar surface patch from a single image. The method exploits the relationship between the orientation o...

Active Unsupervised Texture Segmentation on a Diffusion Based Feature Space
In this paper, we propose a novel and efficient approach for active unsurpervised texture segmentation. First, we show how we can extract a small set of good features for texture ...

Hierarchical Procrustes Matching for Shape Retrieval
We introduce Hierarchical Procrustes Matching (HPM), a segment-based shape matching algorithm which avoids problems associated with purely global or local methods and performs wel...
