Ultralow-power processing array for image enhancement and edge detection
(Institute of Electrical and Electronics Engineers, 2012)
This paper presents a massively parallel processing array designed for the 0.13-μm 1.5-V standard CMOS base process of a commercial 3-D through-silicon via stack. The array, which will constitute one of the fundamental ...

Single-Exposure HDR Technique Based on Tunable Balance Between Local and Global Adaptation
(Institute of Electrical and Electronics Engineers, 2016)
This brief describes a high-dynamic-range technique that compresses wide ranges of illuminations into the available signal range with a single exposure. An online analysis of the image histogram provides the sensor with ...

Impact of thermal throttling on long-term visual inference in a cpu-based edge device
(Multidisciplinary Digital Publishing Institute (MDPI), 2020)
Many application scenarios of edge visual inference, e.g., robotics or environmental monitoring, eventually require long periods of continuous operation. In such periods, the processor temperature plays a critical role to ...

Image Sensing Scheme Enabling Fully-Programmable Light Adaptation and Tone Mapping with a Single Exposure
(Institute of Electrical and Electronics Engineers, 2016)
This letter presents new insights into a high dynamic range (HDR) technique recently reported. We demonstrate that two intertwined photodiodes per pixel can perform tone mapping under unconstrained illumination conditions ...

Smart imaging for power-efficient extraction of Viola-Jones local descriptors
(Society of Photo-Optical Instrumentation Engineers, 2014)
In computer vision, local descriptors permit to summarize relevant visual cues through feature vectors. These vectors constitute inputs for trained classifiers which in turn enable different high-level vision tasks. While ...

Bottom-up performance analysis of focal-plane mixed-signal hardware for Viola–Jones early vision tasks
(John Wiley & Sons, 2015)
Focal-plane mixed-signal arrays have traditionally been designed according to the general claim that moderate accuracy in processing is affordable. The performance of their circuitry has been analyzed in these terms without ...

Low-power focal-plane dynamic texture segmentation based on programmable image binning and diffusion hardware
(Society of Photo-Optical Instrumentation Engineers, 2009)
Stand-alone applications of vision are severely constrained by their limited power budget. This is one of the main reasons why vision has not yet been widely incorporated into wireless sensor networks. For them, ...

TFET-based Well Capacity Adjustment in Active Pixel Sensor for Enhanced High Dynamic Range
(Institute of Electrical and Electronics Engineers, 2017)
We present a Tunnel Field-Effect Transistor (TFET)-based pixel circuit for well capacity adjustment that does not require subthreshold operation on the part of the reset transistor. In CMOS, this subthreshold operation ...
