Lipschitz Learning for Signal Recovery

no code implementations4 Oct 2019 Hong Jiang, Jong-Hoon Ahn, Xiaoyang Wang

We will develop a theoretical framework to characterize the signals that can be robustly recovered from their observations by an ML algorithm, and establish a Lipschitz condition on signals and observations that is both necessary and sufficient for the existence of a robust recovery.

Block-wise Lensless Compressive Camera

no code implementations19 Jan 2017 Xin Yuan, Gang Huang, Hong Jiang, Paul Wilford

2) The coding patterns used in each block can be the same, therefore the sensing matrix is only of the block size compared to the entire image size in existing $\text{L}^2\text{C}^2$.

Lensless Compressive Imaging

no code implementations14 Aug 2015 Xin Yuan, Hong Jiang, Gang Huang, Paul Wilford

We develop a lensless compressive imaging architecture, which consists of an aperture assembly and a single sensor, without using any lens.

Noise Analysis for Lensless Compressive Imaging

no code implementations12 Feb 2014 Hong Jiang, Gang Huang, Paul Wilford

In this paper, we perform noise analysis of this lensless compressive imaging architecture and compare it with pinhole aperture imaging and lens aperture imaging.

Signal to Noise Ratio in Lensless Compressive Imaging

no code implementations4 Feb 2014 Hong Jiang, Gang Huang, Paul Wilford

We will show that the SNR in the LCI is independent of the image resolution, while the SNR in either pinhole aperture imaging or lens aperture imaging decreases as the image resolution increases.

Multi-view in Lensless Compressive Imaging

no code implementations17 Jun 2013 Hong Jiang, Gang Huang, Paul Wilford

Multi-view images are acquired by a lensless compressive imaging architecture, which consists of an aperture assembly and multiple sensors.
