| Outline of Final Research Achievements |
In this research project, we have proposed a new similarity measure for protein structure comparison that uses a set of multi-view visualization images of 3D protein structures. The advantage of our method is that distinctive structural information can be embedded in the visualization. In this approach, each set of multi-view images is represented by a subspace, while applying LBP feature extraction to the image set. The similarity between two protein structures is then characterized by the distance between two points which are corresponding to different two subspaces, on a Grassman manifold. The proposed method was evaluated by classification experiments on 7 protein classes based on SCOP (alpha, beta, alpha/beta, alpha+beta, multidomain protein, membrane, and small protein), using 700 randomly selected proteins. In the experiments, our method significantly outperformed the CE and FATCAT alignment methods. In addition, we have constructed a view-based protein comparison (VPC) system.
