Radix-2 Fast Fourier Transform, real or complex sin/cos transform
A implementation of the discrete Fourier transform in visual basic classic.
文章介绍了从三角函数求和引入傅里叶级数,并且介绍了吉布斯现象的数学证明(我当初就是在搜索吉布斯现象的数学证明时搜索到的这篇文章),文章是台湾国立交通大学的林琨奇教授写的,非常好!
为了验证Fourier-Mellin矩图像识别中的识别能力,本文研究了其在两种坐标下的计算和重建效果、抗噪性试验。在笛卡尔坐标下,图像重建直接计算,不必转换为极坐标,避免极坐标在了转换时产生的几何和计算误差,试验表明:笛卡尔坐标下,Four...
