Hey there,

unfortunately, OpenCV has no shape contest (SC) implementation accepted, yet. You can find here a C++ implementation that was implemented analogeously to Belongie et al. (2000, 2001, 2002) (I'm not sure if the second link is really their's): http://www.umiacs.umd.edu/~zhengyf/PointMatching.htm

The original (?) MATLAB-implementation can be found here: http://www.eecs.berkeley.edu/Research/Projects/CS/vision/shape/sc_digits.html

C#-implementation: http://www.pscode.com/vb/scripts/ShowCode.asp?txtCodeId=7465&lngWId=10

And see what happens here (someone made there a mistake to mix up shape matching and shape context, so read carefully the documentation if you read about shape matching in OpenCV that uses Hu moments): http://stackoverflow.com/questions/3146546/objective-c-implementation-of-shape-context-algorithm-image-matching

Here the Hu-moments-based shape matching.. Maybe it already satisfies your needs as SC is tricky to implement by yourself. Here the link to matching (...): http://docs.opencv.org/modules/imgproc/doc/structural_analysis_and_shape_descriptors.html

And see what happens here (someone in the following link. Someone made there a mistake to mix up shape matching and shape context, so read carefully the documentation if you read about shape matching in OpenCV that uses Hu moments): moments and shape matching using shape context. There's nothing for SC in OpenCV like the descriptor (shape context/the histogram [log(r),theta]), assignment problem solver (like hungarian [by munkres in O(n^3)], ...) etc.] or deforming algorithms to model transformations (TPS - Thin Plate Spline, ...) etc. as far as I know).
