Detector de contorns basat en el domini transformat
(2009-02-04)RESUM En aquest document es presenta un detector de contorns d’imatges basat en el domini transformat. A partir de la interpretació de la transformada de Fourier de la imatge i la seva formulació ... -
New FFT/IFFT Factorizations with Regular Interconnection Pattern Stage-to-Stage Subblocks
(2008-04-02)Les factoritzacions de la FFT (Fast Fourier Transform) que presenten un patró d’interconnexió regular entre factors o etapes son conegudes com algorismes paral·lels, o algorismes de Pease, ja que foren ... -
Radix-R FFT and IFFT factorizations for parallel implementation
(2009)Two radix-R regular interconnection pattern families of factorizations for both the FFT and the IFFT -also known as parallel or Pease factorizations- are reformulated and presented. Number R is any power ... -
Two Families of Radix-2 FFT Algorithms With Ordered Input and Output Data
(2009)Two radix-2 families of fast Fourier transform (FFT) algorithms that have the property that both inputs and outputs are addressed in natural order are derived in this letter. The algorithms obtained ...
