NTIRE 2020 Challenge on Spectral Reconstruction from an RGB Image
Boaz Arad, Radu Timofte, Ohad Ben-Shahar +4
This paper reviews the second challenge on spectral reconstruction from RGB images, i.e., the recovery of whole-scene hyperspectral (HS) information from a 3-channel RGB image. As…
Pyramidal Edge-maps and Attention based Guided Thermal Super-resolution
Honey Gupta, Kaushik Mitra
Guided super-resolution (GSR) of thermal images using visible range images is challenging because of the difference in the spectral-range between the images. This in turn means tha…
Unsupervised Single Image Underwater Depth Estimation
Honey Gupta, Kaushik Mitra
Depth estimation from a single underwater image is one of the most challenging problems and is highly ill-posed. Due to the absence of large generalized underwater depth datasets a…
Phase retrieval for Fourier Ptychography under varying amount of measurements
Lokesh Boominathan, Mayug Maniparambil, Honey Gupta +2
Fourier Ptychography is a recently proposed imaging technique that yields high-resolution images by computationally transcending the diffraction blur of an optical system. At the c…
