Lensless Imaging with Focusing Sparse URA Masks in Long-Wave Infrared and its Application for Human Detection

Ilya Reshetouski, Hideki Oyaizu, Kenichiro Nakamura, Ryuta Satoh, Suguru Ushiki, Ryuichi Tadano +2

ECCV 2020poster

We introduce a lensless imaging framework for contemporary computer vision applications in long-wavelength infrared (LWIR). The framework consists of two parts: a novel lensless imaging method that utilizes the idea of local directional focusing for optimal binary sparse coding, and lensless imaging…

Depth Selective Camera: A Direct, On-Chip, Programmable Technique for Depth Selectivity in Photography

Ryuichi Tadano, Adithya Kumar Pediredla, Ashok Veeraraghavan

ICCV 2015poster

Time of flight (ToF) cameras use a temporally modulated light source and measure correlation between the reflected light and a sensor modulation pattern, in order to infer scene depth. In this paper, we show that such correlational sensors can also be used to selectively accept or reject light rays…
