abstract = "2D electrophoresis is a well known method for protein separation
which is extremely useful in the field of proteomics. Each spot in
the image represents a protein accumulation and the goal is to
perform a differential analysis between pairs of images to study
changes in protein content. It is thus necessary to register two
images by finding spot correspondences. Although it may seem a
simple task, generally, the manual processing of this kind of
images is very cumbersome. The complete task of individual spot
matching and gel registration is a complex and time consuming
process when strong variations between corresponding sets of spots
are expected. Besides, because an one-to-one mapping is expected
between the two images, missing spots there may exist on both
images (i.e. spots without correspondence). In order to solve this
problem, this paper proposes a new distance together with a
correspondence estimation algorithm based on graph matching which
takes into account the structural information between the detected
spots. Each image is represented by a graph and the task is to
find an isomorphism between subgraphs. Successful experimental
results using real data are presented, including a comparative
performance evaluation. .",
