Automatic clustering algorithm based on multi-objective Immunized PSO to classify actions of 3D human models

► An automatic clustering algorithm MOIMPSO is proposed. ► Proposed algorithm can provide a single best solution in the Pareto optimal front. ► Simulation studies are carried out on 11 datasets to evaluate the performance. ► The MOIMPSO provides superior performance over MOCK, MOPSO and MOCLONAL. ► Proposed algorithm is applied to classify the physical actions of 3D human models.
