Abstract
We introduce a new; model for multiscale analysis of space-time echocardiog raphic sequences. The proposed nonlinear partial differential equation, rep resenting the multiscale analysis, filters the sequence while keeping the s pace-time coherent structures, It combines the ideas of regularized Perona- Malik anisotropic diffusion and the Galilean invariant mol ie multiscale an alysis of Alvarez, Guichard, Lions and Morel. A numerical method for solvin g the proposed partial differential equation is suggested and its stability is shown. Computational results on synthesized and real sequences are prov ided, A qualitative and quantitative evaluation of the accuracy of the meth od is presented.
