Sound representation methods for spectro-temporal receptive field estimation
TLDR
The spectro-temporal receptive field (STRF) of an auditory neuron describes the linear relationship between the sound stimulus in a time-frequency representation and the neural response. Expand

Hippocampal episode fields develop with learning
Several recent studies have shown that hippocampal neurons fire during the delay period in between trials and that these firing patterns differ when different behaviors are required, suggesting thatExpand

The In-Crowd Algorithm for Fast Basis Pursuit Denoising
TLDR
We introduce a fast method, the “in-crowd” algorithm, for finding the exact solution to basis pursuit denoising problems. Expand

Light field image sensors based on the Talbot effect.
We present a pixel-scale sensor that uses the Talbot effect to detect the local intensity and incident angle of light. The sensor comprises two local diffraction gratings stacked above a photodiode.Expand

An angle-sensitive CMOS imager for single-sensor 3D photography
TLDR
This paper demonstrates a 150kpixel image sensor, which captures 3D scenes using only a single convex lens. Expand

Lensless Ultra-Miniature Imagers Using Odd-Symmetry Spiral Phase Gratings
We introduce a new type of diffractive element based on odd-symmetry phase gratings. Spiral arrangements of these gratings over photosensors constitute a new class of unprecedentedly-smallExpand

Accelerated Compressed Sensing Based CT Image Reconstruction
TLDR
We propose a new algorithm that accelerates the CS-based reconstruction by using a fast pseudopolar Fourier Fourier based Radon transform and rebinning the diverging fan beams to parallel beams. Expand

Enhanced angle sensitive pixels for light field imaging
Previously demonstrated angle sensitive pixels (ASPs) have been shown to enable integrated digital light-field imaging in CMOS, but suffer from significantly reduced pixel quantum efficiency andExpand

Fluorescent imaging and localization with angle sensitive pixel arrays in standard CMOS
We demonstrate an optical sensor array which is capable of locating multiple, small fluorescent objects in three-dimensional space. Manufactured in an unmodified 130nm CMOS process, the sensorExpand

A microscale camera using direct Fourier-domain scene capture.
We demonstrate a chip-scale (<1 mm(2)) sensor, the Planar Fourier Capture Array (PFCA), capable of imaging the far field without any off-chip optics. The PFCA consists of an array of angle-sensitiveExpand
