Image Compression and Decompression using nested Inverse Fourier Transform and Fast Fourier Transform
Image compression is the reduction or elimination of redundancy in image data representation in order to achieve savings in storage and communication. In this paper we propose a method for image compression and decompression using nested IFFT and FFT which works on both color and grey images. This technique is simple in implementation and utilizes less memory and also requires less computationa...
متن کاملInverse Fourier Transform in the Gamma Coordinate System
This paper provides auxiliary results for our general scheme of computed tomography. In 3D parallel-beam geometry, we first demonstrate that the inverse Fourier transform in different coordinate systems leads to different reconstruction formulas and explain why the Radon formula cannot directly work with truncated projection data. Also, we introduce a gamma coordinate system, analyze its proper...
متن کاملOn the inverse windowed Fourier transform
The inversion problem concerning the windowed Fourier transform is considered. It is shown that, out of the infinite solutions that the problem admits, the windowed Fourier transform is the “optimal” solution according to a maximum-entropy selection criterion.
متن کاملA Variable Density Sampling Scheme for Compressive Fourier Transform Interferometry
Fourier Transform Interferometry (FTI) is an appealing Hyperspectral (HS) imaging modality in the applications demanding high spectral-resolution, such as fluorescence microscopy. However, the effective resolution of FTI is indeed limited due to the durability of biological elements when exposed to illuminating light; since over exposed biological elements suffer from photo-bleaching, i.e., a p...
متن کاملMultilevel Illumination Coding for Fourier Transform Interferometry in Fluorescence Spectroscopy
Fourier Transform Interferometry (FTI) is an interferometric procedure for acquiring HyperSpectral (HS) data. Recently, it has been observed that the light source highlighting a (biologic) sample can be coded before the FTI acquisition in a procedure called Coded Illumination-FTI (CI-FTI). This turns HS data reconstruction into a Compressive Sensing (CS) problem regularized by the sparsity of t...
