摘要
介绍了快速傅立叶变换在苹果形状识别中的应用,首先需要将苹果图像的边缘像素进行极坐标转换,经过FFT变换后的数据较多,因此还需采用主成份分析法对其进行处理,得到能够描述苹果形状的两个主成份值。
This paper introduces the application of Fast Fourier transform in apple shape recognition,we first need to convert the apple image edges data into polar,through FFT transform the data are more than ten,so it should be processed by the principal component analysis method,the two main component values which are the result of the processing can describe the shape of apples.
