Pablo Arbelaez Research Projects

Contours and Junctions
Collaboration with Michael Maire, Charless Fowlkes and Jitendra Malik

Original Image	Contours	Junctions (in red)

Description

We propose a high performance contour detector that operates by computing brightness, color and texture gradients at multiple scales and globalizing this local information through spectral graph partitioning. The contours obtained are then used to localize junctions in the image.

Code for Global Pb (gPb):

• [Full package with Matlab 64-bit Linux MEX files]

• [Source code for MEX files] (Distributed under the GNU AGPL)

Note: The precompiled package also includes the segment program from the BSE.
