High-Level Performance Evaluation of Object Detection Based on Massively Parallel Focal-Plane Acceleration Requiring Minimum Pixel Area Overhead
(Springer, 2016)
Smart CMOS image sensors can leverage the inherent data-level parallelism and regular computational flow of early vision by incorporating elementary processors at pixel level. However, it comes at the cost of extra area ...

Design of a smart SiPM based on focal-plane processing elements for improved spatial resolution in PET
(The International Society for Optics and Photonics, 2011)
Single-photon avalanche diodes are compatible with standard CMOS. It means that photo-multipliers for scintillation detectors in nuclear medicine (i. e. PET, SPECT) can be built in inexpensive technologies. These silicon ...

Image filtering by reduced kernels exploiting kernel structure and focal-plane averaging
(Institute of Electrical and Electronics Engineers, 2011)
Incorporating multi-resolution capabilities into imagers renders additional power saving mechanisms in the subsequent image processing. In this paper, we show how, by exploiting a certain mask structure, 3 × 3 kernels can ...

Demo: Image Sensing Scheme Enabling Fully-Programmable Light Adaptation and Tone Mapping with a Single Exposure
(Association for Computing Machinery, 2016)
This demo showcases a High Dynamic Range (HDR) technique recently reported. We demonstrate that two intertwined photodiodes per pixel can perform tone mapping under unconstrained illumination conditions with a single ...

Focal-Plane Scale Space Generation with a 6T Pixel Architecture
(Society for Imaging Science and Technology, 2016)
Aiming at designing a CMOS image sensor that combines high fill factor and focal-plane implementation of instrumental image processing steps, we propose a simple modification in a standard pixel architecture in order ...

A VLSI-oriented and power-efficient approach for dynamic texture recognition applied to smoke detection
(2009)
The recognition of dynamic textures is fundamental in processing image sequences as they are very common in natural scenes. The computation of the optic flow is the most popular method to detect, segment and analyse dynamic ...
