Spatial Phase-Sweep: Increasing temporal resolution of transient imaging using a light source array
Ryuichi Tadano, Adithya Kumar Pediredla, Kaushik Mitra +1
Transient imaging or light-in-flight techniques capture the propagation of an ultra-short pulse of light through a scene, which in effect captures the optical impulse response of t…
Toward Long Distance, Sub-diffraction Imaging Using Coherent Camera Arrays
Jason Holloway, M. Salman Asif, Manoj Kumar Sharma +4
In this work, we propose using camera arrays coupled with coherent illumination as an effective method of improving spatial resolution in long distance images by a factor of ten an…
Depth Fields: Extending Light Field Techniques to Time-of-Flight Imaging
Suren Jayasuriya, Adithya Pediredla, Sriram Sivaramakrishnan +2
A variety of techniques such as light field, structured illumination, and time-of-flight (TOF) are commonly used for depth acquisition in consumer imaging, robotics and many other…
FlatCam: Thin, Bare-Sensor Cameras using Coded Aperture and Computation
M. Salman Asif, Ali Ayremlou, Aswin Sankaranarayanan +2
FlatCam is a thin form-factor lensless camera that consists of a coded mask placed on top of a bare, conventional sensor array. Unlike a traditional, lens-based camera where an ima…
TabletGaze: Unconstrained Appearance-based Gaze Estimation in Mobile Tablets
Qiong Huang, Ashok Veeraraghavan, Ashutosh Sabharwal
We study gaze estimation on tablets, our key design goal is uncalibrated gaze estimation using the front-facing camera during natural use of tablets, where the posture and method o…
FPA-CS: Focal Plane Array-based Compressive Imaging in Short-wave Infrared
Huaijin Chen, M. Salman Asif, Aswin C. Sankaranarayanan +1
Cameras for imaging in short and mid-wave infrared spectra are significantly more expensive than their counterparts in visible imaging. As a result, high-resolution imaging in thos…
DistancePPG: Robust non-contact vital signs monitoring using a camera
Mayank Kumar, Ashok Veeraraghavan, Ashutosh Sabharval
Vital signs such as pulse rate and breathing rate are currently measured using contact probes. But, non-contact methods for measuring vital signs are desirable both in hospital set…
