Fourier descriptor, spatial normalization, recognition


This paper presents a novel normalization for the Fourier descriptor, named as Spatial Normalization Fourier Descriptor. This algorithm normalizes the contour in the spatial domain while the traditional Fourier descriptor does in the other domains, such as the frequency domain. This invent greatly improve the performance of the Fourier descriptor, and provides high robust and division degree. It will greatly impulse the pattern recognition of shape and in the so many applications for the flourier descriptor it will be highlighted. Lastly the experiment verifies it and it outperform the traditional Fourier descriptor.
