Towards Fast and Light-Weight Restoration of Dark Images
Mohit Lamba, Atul Balaji, Kaushik Mitra
The ability to capture good quality images in the dark and near-zero lux conditions has been a long-standing pursuit of the computer vision community. The seminal work by Chen et a…
Video Reconstruction by Spatio-Temporal Fusion of Blurred-Coded Image Pair
S Anupama, Prasan Shedligeri, Abhishek Pal +1
Learning-based methods have enabled the recovery of a video sequence from a single motion-blurred image or a single coded exposure image. Recovering video from a single motion-blur…
A Unified Framework for Compressive Video Recovery from Coded Exposure Techniques
Prasan Shedligeri, Anupama S, Kaushik Mitra
Several coded exposure techniques have been proposed for acquiring high frame rate videos at low bandwidth. Most recently, a Coded-2-Bucket camera has been proposed that can acquir…
FlatNet: Towards Photorealistic Scene Reconstruction from Lensless Measurements
Salman S. Khan, Varun Sundar, Vivek Boominathan +2
Lensless imaging has emerged as a potential solution towards realizing ultra-miniature cameras by eschewing the bulky lens in a traditional camera. Without a focusing lens, the len…
Deep Atrous Guided Filter for Image Restoration in Under Display Cameras
Varun Sundar, Sumanth Hegde, Divya Kothandaraman +1
Under Display Cameras present a promising opportunity for phone manufacturers to achieve bezel-free displays by positioning the camera behind semi-transparent OLED screens. Unfortu…
UDC 2020 Challenge on Image Restoration of Under-Display Camera: Methods and Results
Yuqian Zhou, Michael Kwan, Kyle Tolentino +42
This paper is the report of the first Under-Display Camera (UDC) image restoration challenge in conjunction with the RLQ workshop at ECCV 2020. The challenge is based on a newly-co…
Monocular Retinal Depth Estimation and Joint Optic Disc and Cup Segmentation using Adversarial Networks
Sharath M Shankaranarayana, Keerthi Ram, Kaushik Mitra +1
One of the important parameters for the assessment of glaucoma is optic nerve head (ONH) evaluation, which usually involves depth estimation and subsequent optic disc and cup bound…
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…
Optimal HDR and Depth from Dual Cameras
Pradyumna Chari, Anil Kumar Vadathya, Kaushik Mitra
Dual camera systems have assisted in the proliferation of various applications, such as optical zoom, low-light imaging and High Dynamic Range (HDR) imaging. In this work, we explo…
multi-patch aggregation models for resampling detection
Mohit Lamba, Kaushik Mitra
Images captured nowadays are of varying dimensions with smartphones and DSLR's allowing users to choose from a list of available image resolutions. It is therefore imperative for f…
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…
Harnessing Multi-View Perspective of Light Fields for Low-Light Imaging
Mohit Lamba, Kranthi Kumar, Kaushik Mitra
Light Field (LF) offers unique advantages such as post-capture refocusing and depth estimation, but low-light conditions limit these capabilities. To restore low-light LFs we shoul…
