Shape Recognition and Classification Based on Poisson Equation- Fourier-Mellin Moment Descriptor
Poisson equation Fourier-Mellin moment shape recognition shape classification
2009/8/19
In this paper, we present a new shape descriptor, which is named Poisson equation-Fourier-Mellin moment Descriptor. We solve the Poisson equation in the shape area, and use the solution to get feature...
