Fast fourier transform optional soft module easily performs cross correlation Leica QFFT
The Leica QFFT, optional software module available for Leica QWin, performs forward and inverse fast Fourier transformations on samples features, which are not apparent on first inspection for applications such as metrology, strain analysis and documentation authentication.
Data of transformed images may undergo cross correlation or convolution with any size kernel. The user may perform complex convolution filters such as high pass, low pass, band pass and notch pass filters, especially for required large kernel analysis.
Leica QFFT is included with Leica QWin Standard and QWin Pro.
Your Advantages
Sample feature analysisIdentifies repetitive (curvilinear grating, curved dot screen) or periodic (line grating, dot screen) structures |
Complex convolution filterAllows user to apply various effects on images |
Digital image correlationPerforms fast, tracking and image registration for accurate 2D and 3D measurement of displacement or strain from digital image |
Floating part representation storageSupports a wider range of values than fixed point |
Fourier transformsForward and inverse Fourier transforms - performs calculations at high speed |
