傅里叶常数因子描述符 FCFD
We suggest a the corner based Fourier Descriptors of the object, which are taken as the features of 2-D objects and form the input of BP neural network. A multilayered perceptron architecture is used for the recognition of airplane.
本文提出了角点傅里叶描述子,并将它作为二维目标的特征和神经网络的输入,用于构成一基于BP神经网络的飞机目标识别系统,该识别系统对旋转、位移、尺度变换具有不变性,计算机模拟结果表明该识别器对空中飞机的识别具有很高的识别率和联想能力。
