FFT mainly involved important role in electronics & communication field. The various types of FFT radix algorithm have analyzed and is to be modified in future. As a result of its exhaustive computational necessities, it occupies large area and consumes high power if implemented in hardware. Efficient algorithms are developed to improve its architecture.In this paper, we have conversed about FF...

Similar in nature to an image mosaic, a photo-stencil is a rendering of a binary target image by an arrangement of smaller binary stencil images. This paper presents a method for efficiently creating photo-stencil images, making use of the Fast Fourier Transform to speed up costly computations. The resulting photo-stencils are a new and interesting form of nonphotorealistic rendering.

We calculate the local Fourier transformations for a class of Q l -sheaves. In particular, we verify a conjecture of Laumon and Malgrange ([L] 2.6.3).

This paper describes the use of a resynthesis strategy in testing an auditory model, specifically a version of the DOMIN model. The steps by which the original speech is processed to produce a reduced, auditory (DOMIN) spectrum are described; subsequently, the reduced representation is used to produce resynthesised speech having the same auditory spectrum. In light ofthis equivalence, the exten...

This paper looks at one of the jewels of mathematics, the Fourier series / transform and briefly surveys its applications and looks at possible ways of enhancing the performance of the fast Fourier transform

We calculate the local Fourier transformations for a class of Q l -sheaves. In particular, we verify a conjecture of Laumon and Malgrange ([L] 2.6.3).

The paper presents the Kinectofon, an instrument for creating sounds through free-hand interaction in a 3D space. The instrument is based on the RGB and depth image streams retrieved from a Microsoft Kinect sensor device. These two image streams are used to create di↵erent types of motiongrams, which, again, are used as the source material for a sonification process based on inverse FFT. The in...

We propose an algorithm that uses the discrete wavelet transform (DWT) as a tool to compute the discrete Fourier transform (DFT). The Cooley-Tukey FFT is shown to be a special case of the proposed algorithm when the wavelets in use are trivial. If no intermediate coe cients are dropped and no approximations are made, the proposed algorithm computes the exact result, and its computational comple...
