Algorithms for subgraph isomorphism detection

Subgraph isomorphism is an NP Complete problem. The most widely used algorithm is the one proposed by Ullman.

Can someone please explain the algorithm to me in layman's language? I read the above paper by him, but couldn't understand much.

What other algorithms exist for this problem?

I am working on an image processing project.

+4  A: 

VFLib2 is a C++ library for graph isomorphism finding. It also includes an Ullman implementation: http://amalfi.dis.unina.it/graph/db/vflib-2.0/doc/vflib.html
