Similarity assessment of 3D CAD model based on random walks graph matching
Yusheng Liu · Journal of Mechanical & Electrical Engineering · 2010
Aiming at enhancing the efficiency of 3D CAD model retrieval,a new similarity assessment algorithm based on random-walks was proposed.Graph translation function was used to eliminate the sink nodes in feature dependency graph.Probability normalization function was used to eliminate the unreasonable disturbance among features.3D CAD models were efficiently retrieved.Experimental results demon-strate that the method is efficient and effective.
