4D Lightfield Reconstruction
Sparsity in the discrete vs. continuous Fourier domain, and our reconstruction results: (a) The discrete Fourier transform(top) of a particular 2D angular slice wu, wv of the crystal ball's light field, and its reconstructed continuous version (bottom). (b) A grid showing the original images from the Stanford light field archive. The images used by our algorithm are highlighted (courtesy of [Stanf
SFFT: Sparse Fast Fourier Transform
Sparse Fast Fourier Transform : The discrete Fourier transform (DFT) is one of the most important and widely used computational tasks. Its applications are broad and include signal processing, communications, and audio/image/video compression. Hence, fast algorithms for DFT are highly valuable. Currently, the fastest such algorithm is the Fast Fourier Transform (FFT), which computes the DFT of an
