The Fast Fourier Transform (FFT) is an implementation of the Discrete Fourier Transform (DFT) using a divide-and-conquer approach. A DFT can transform any discrete signal, such as an image, to and ...

Back in 1811 there was a mathematical technique proposed, it now known to us as Joseph Fourier's Fourier Technique, a technique which eventually translated itself into one of the most basic ways we ...

This is a design and fabrication of a CMOS image sensor with a non-uniform layout of pixels that enables the arithmetic Fourier Transform (AFT) algorithm to be used for image compression. A ...

This is the Fourier Transform. You can thank it for providing the music you stream every day, squeezing down the images you see on the Internet into tiny little JPG files, and even powering your noise ...

Many cameras use a colour filter array (also known as a Bayer mask) to capture colour images with a single sensor. The sub-sampling of the image often causes reduced resolution and colour fringing.

Different forms of linear transformations, such as the Fourier transform, are widely employed in processing of information in various applications. These transformations are generally implemented in ...

Quantitative optical measurements of deep subwavelength, three-dimensional (3D), nanometric structures with sensitivity to sub-nanometer details address a ubiquitous measurement challenge. A Fourier ...
