                         topic in the computing knowledge domain since we have observed a 
                         high demand arising from society for efficient techniques to 
                         perform this activity. Spherical Harmonics (SPHARMs) have been 
                         widely used in the three-dimensional (3D) object processing 
                         domain. Harmonic coefficients generated by this mathematical 
                         theory are considered a robust source of information about 3D 
                         objects. In parallel, Ford-Fulkerson is a classical method in 
                         graph theory that solves network flows problems. In this work we 
                         demonstrate the potential of using SPHARMs along with the 
                         Ford-Fulkerson method, respectively as descriptor and similarity 
                         measure. This article also shows how we adapted the later to 
                         transform it into a similarity measure. Our approach has been 
                         validated by a 3D medical dataset composed by 3D left ventricle 
                         surfaces, some of them presenting Congestive Heart Failure (CHF). 
                         The results indicated an average precision of 90%. In addition, 
                         the execution time was 65% lower than a descriptor previously 
                         tested. With the results obtained we can conclude that our 
                         approach, mainly the Ford-Fulkerson adaptation proposed, has a 
                         great potential to retrieve 3D medical objects.",
