Localisation is performed using the fast Fourier transform-based template matching to obtain a seed point located on the optic disc which is then used as an input to the region growing technique for the purpose of segmentation. Three sets of fundus images, namely DRIVE, MESSIDOR and a LOCAL ...

最近买了一本《机器视觉算法与应用第二版》书,书中再次提到该方法:使用傅里叶变换进行滤波处理的真正好处是可以通过使用定制的滤波器来消除图像中某些特定频率,例如这些特定频率可能代表着图像中重复出现的纹理。 在网络上很多的PS教程中,也有提到使用FFT来进行去网纹的操作,其中最为广泛的是使用PS小插件FOURIER TRANSF...
Overview The FFT graph is offered as a template class that is available with 2 template specializations, that offer varied features and interfaces: window interface (TP_API == 0) or stream interface (TP_API == 1). // classes template < typename TT_D
templatematching;imageprocessing 图像匹配是一系列图像处理应用和计算机视觉问题中一类很重要的问题。尤其在目标识别、运动估计、自动 化检测等研究和应用领域,图像匹配算法的精确性往往对图像的后期处理起着决定性的作用。为此,一系列的算 法相继提出,以期得到很好的检测效果。总的来说,目前的图像匹配算法主要分为两大...

The matching algorithm proposed in this paper is mainly based on template features and by using the combination of technologies including Principal Component Analysis(PCA) and blocking Fast Fourier Transform(FFT) to implement fast algorithm. In the application of detection of large amount of similar ...
