Provable and Robust Wavefront Sensing via Self-Reference Interferometry
Nebiyou Yismaw, Vishwanath Saragadam, Aswin C. Sankaranarayanan +1
Wavefront sensing involves estimating the phase and intensity of light, enabling a wide range of imaging applications, from adaptive optics and astronomy to biomedical imaging. Sin…
On The Application Of Log Compression and Enhanced Denoising In Contrast Enhancement Of Digital Radiography Images
M. S. Asif, Mahesh Raveendranatha Panicker
Digital radiography (DR) is becoming popular for the point of care imaging in the recent past. To reduce the radiation exposure, controlled radiation based on as low as reasonably…
Coded Illumination for 3D Lensless Imaging
Yucheng Zheng, M. Salman Asif
Mask-based lensless cameras offer a novel design for imaging systems by replacing the lens in a conventional camera with a layer of coded mask. Each pixel of the lensless camera en…
Coded Illumination for Improved Lensless Imaging
Yucheng Zheng, M. Salman Asif
Mask-based lensless cameras can be flat, thin, and light-weight, which makes them suitable for novel designs of computational imaging systems with large surface areas and arbitrary…
A Simple Framework for 3D Lensless Imaging with Programmable Masks
Yucheng Zheng, Yi Hua, Aswin C. Sankaranarayanan +1
Lensless cameras provide a framework to build thin imaging systems by replacing the lens in a conventional camera with an amplitude or phase mask near the sensor. Existing methods…
Solving Phase Retrieval with a Learned Reference
Rakib Hyder, Zikui Cai, M. Salman Asif
Fourier phase retrieval is a classical problem that deals with the recovery of an image from the amplitude measurements of its Fourier coefficients. Conventional methods solve this…
Learning Illumination Patterns for Coded Diffraction Phase Retrieval
Zikui Cai, Rakib Hyder, M. Salman Asif
Signal recovery from nonlinear measurements involves solving an iterative optimization problem. In this paper, we present a framework to optimize the sensing parameters to improve…
Non-Adversarial Video Synthesis with Learned Priors
Abhishek Aich, Akash Gupta, Rameswar Panda +3
Most of the existing works in video synthesis focus on generating videos using adversarial learning. Despite their success, these methods often require input reference frame or fai…
Joint Image and Depth Estimation with Mask-Based Lensless Cameras
Yucheng Zheng, M. Salman Asif
Mask-based lensless cameras replace the lens of a conventional camera with a custom mask. These cameras can potentially be very thin and even flexible. Recently, it has been demons…
A Dual Camera System for High Spatiotemporal Resolution Video Acquisition
Ming Cheng, Zhan Ma, M. Salman Asif +4
This paper presents a dual camera system for high spatiotemporal resolution (HSTR) video acquisition, where one camera shoots a video with high spatial resolution and low frame rat…
