Transformation converts data from spatial domain to a two-dimensional frequency using a transformation algorithm. We have applied here Fast Fourier Transform (FFT) algorithm, which reduces the number of computations from something on the order of N2 to N log N. The image is projected and ...
The experimental results show a significant speedup of the algorithm in GPU than that of CPU based implementation. It is expected that this will accelerate many compute intensive image processing application. 展开 关键词: Fast Fourier Transformation GPGPU CUDA Image Processing Frequency Domain Image ...
In a number of imaging modalities, the Fast Fourier Transform (FFT) is being used for the processing of images in its frequency domain rather than spatial domain. It is an important image processing tool which is used to decompose an image into its sine
Fourier-transformation, phase-iteration, and least-square-fit image processing for Young's fringe pattern The fast Fourier transform, phase iteration, and the least-square fit are combined into an automated processing technique for the analysis of Young's fring... G Jie,C Fang - 《Applied Optic...
Fourier transformationis the mathematical procedure connectings(t)andS(ω). Ifs(t)is specified,S(ω) may be computed, and vice versa.The equations require some knowledge of complex numbers and calculus to make sense, but don't worry if you don't understand them. There is some supplemental ...
Since computers work with a finite number of limited-resolution numbers, the integral transformation describing the FT is converted into its discrete version, DFT (discrete Fourier transform). DFT will be treated later on. The FT has its inverse function, or inverse Fourier transform (IFT), that...
High quality sub-unity image shift which is crucial to the approach is accomplished by implementing the shift theorem of Fourier transformation. It is well known that under the Nyquist sampling criterion, the most accurate image interpolation can be achieved with the interpolating function (sinc ...
PURPOSE:To enable shifting in an imaging area without limitation by a picture element size by executing rotation arithmetic processing of a phase angle portion proportional to time integrated quantity to a detected resonance signal, and thereafter conducting Fourier transformation for shifting.

Using this representation, the quantum multiply–adder (QMA), as shown in Fig. 5a, can realize the following transformation, [Math Processing Error]Πm,n±|a⟩|b⟩|c⟩=|a⟩|b⟩|c±a×b⟩, (33) where m and n denote the number of digits of a and b, respectively....
