摘要：

We introduce a new; model for multiscale analysis of space-time echocardiographic sequences. The proposed nonlinear partial differential equation, representing the multiscale analysis, filters the sequence while keeping the space-time coherent structures, It combines the ideas of regularized Perona-Malik anisotropic diffusion and the Galilean invariant mol ie multiscale analysis of Alvarez, Guichard, Lions and Morel. A numerical method for solving the proposed partial differential equation is suggested and its stability is shown. Computational results on synthesized and real sequences are provided, A qualitative and quantitative evaluation of the accuracy of the method is presented.
