傅立叶描述子在手势识别中的应用

THE APPLICATION OF FOURIER DESCRIPTORS TO THE RECOGNITION OF ALPHABET GESTURE

本文分析了具有旋转、平移和尺度变换不变性,并且与边界的起点位置无关的傅立叶描述子,并把傅立叶描述子及欧氏距离应用于字母手势的识别中。实验结果表明,利用傅立叶描述子能够有效地识别出有旋转、平移及尺度变换后的同一类字母手势,取得了良好的识别效果。

This paper analyzes Fourier Descriptors which do not change with translation,rotation and scale change,and which are also independent of the location of the beginning point of the image edge.The Fourier descriptors and Euclidean distance are applied to the recognition of the alphabet gesture.The experiment result proves that the recognition ratio is high in case of the translation,rotation and scale change owing to the application of the Fourier Descriptors.
