Using the coarse sampling and the fine interpolation  a novel approach based on singular spectrum analysis (SSA) is presented to decompose the generated TPT into a slowly varying trend and a quickly varying quasi-periodic oscillation. The numerical experiments of the TPT decomposition of toroidal surfaces have been carried out. The results verify that the proposed approach is very effective for the TPT decomposition.
