Course Notes:
You can find a set of course notes prepared for this
course here:
Computing and
Processing Correspondences with Functional Maps (60 pages, 19MB).
Sample Code:
-
The following set of MATLAB scripts implements a method for computing
functional maps described in the paper:
Informative Descriptor Preservation via Commutativity
for Shape Matching, Eurographics 2017.
You can find this code here.
Please see the included README file for an example use of the code.
-
The following set of MATLAB scripts implements the basic
pipeline for computing a map between a pair of shapes using the
functional representation. It is based on the description given in
the following paper and was used to obtain the results presented
in this paper:
Functional Maps: A Flexible Representation of Maps Between
Shapes, SIGGRAPH 2012.
You can find this code here.
To use it, please run the file runme.m inside "clean_code" to see an example
with two shapes (cat0 and cat10). Note that this code requires as
input some shape segmentations (provided for these examples) and tries
to establish correspondences between segments, which are used as input
constraints to find the functional map. The segmentations used to obtain results
shown in the paper can be found here. In addition,
you can find the code for computing persistence-based segmentations (used to generate these results):
here.
-
The following code (also in MATLAB) implements the method described in the paper:
Non-rigid Puzzles, SGP 2016.
You can find this code here.
In particular, you can reproduce the figures presented in the paper by running the script
reproduce_paper_figures.m To run it on your own data,
run the function solveNonRigidPuzzle
with the parameters used for Figure 1 (in the reproduce_paper_figures.m script).
-
The following code implements the method described in the paper:
Point-wise Map Recovery and Refinement from Functional Correspondence, VMV 2015.
You can find this code here.
To use it simply run
demo.m which loads two example shapes. To use it on your own data, simply
replace the shapes with your own (the only requirement is to have pre-computed eigenvectors of the Laplacian
of each shape). See run_cpd.m for the format.
-
The following code implements the method described in the paper:
Supervised Descriptor Learning for Non-Rigid Shape Matching,
NORDIA 2014.
You can find this code here
To use it please look at the the Readme.txt,
which describes how to reproduce Figure 5b of the paper. You need to download the TOSCA dataset
which can be found here.
