FPGA acceleration for feature based processing applications
In this paper, we describe the implementation of an algorithm that combines distributed feature detector (D-HCD) with a rotational invariant feature descriptor (R-HOG).

Role for the Nicotinic Cholinergic System in Movement Disorders; Therapeutic Implications
This work raised the question whether dysregulation of this system may contribute to motor dysfunction and whether drugs targeting nicotinic acetylcholine receptors (nAChRs) may be of therapeutic benefit in movement disorders.

ABT-089 and ABT-894 reduce levodopa-induced dyskinesias in a monkey model of Parkinson’s disease
Here, we examined the effect of two β2 nAChR agonists, ABT-089 and ABT-894, that previously were approved for phase 2 clinical trials for other indications.

Nicotinic Receptor Agonists Reduce l-DOPA–Induced Dyskinesias in a Monkey Model of Parkinson’s Disease
Here, we investigated whether nicotinic acetylcholine receptor (nAChR) agonists reduced LIDs in nonhuman primates.

Nicotine Reduces Established Levodopa-Induced Dyskinesias in a Monkey Model of Parkinson’s Disease
The goal of this study was to determine whether the duration of nicotine administration affects its ability to reduce LIDs in levodopa-primed and levadopa-naíve monkeys and also to test whether tolerance develops to the beneficial effects of nicotine.

Video Object Segmentation through Spatially Accurate and Temporally Dense Extraction of Primary Object Regions
In this paper, we propose a novel approach to extract primary object segments in videos in the ‘object proposal’ domain. The extracted primary object regions are then used to build object models for optimized video segmentation.

The F Region and Topside Ionosphere Response to a Strong Geomagnetic Storm at Arecibo
We analyze the data derived from the Arecibo incoherent scatter radar measurements to investigate the response of the F region and topside ionosphere to a strong geomagnetic storm that occurred during the period of 5–6 August 2011.

Motion Adaptive Signal Integration-High Dynamic Range (MASI-HDR) Video Processing for Dynamic Platforms
SRI’s MASI-HDR (Motion Adaptive Signal Integration-High Dynamic Range) is a novel technique for generating blur-reduced video using multiple captures for each displayed frame while increasing the effective camera dynamic range by four bits or more.

Adaptive Smoothing in Real-Time Image Stabilization
This paper discusses several novel methods that have demonstrated on a real-time platform including an IIR filter, a single Kalman filter and an interactive multi-model filter.

Extended Motion Adaptive Signal Integration Technique for Real-Time Image Enhancement
We propose a Motion Adaptive Signal Integration (MASI) algorithm that operates the sensor at a high frame rate, with real time alignment of individual image frames to form an enhanced quality video output.

A Single Algorithm Combining Exposure and Focus Fusion
This paper proposes an overhauled method of exposure fusion that solves the exposure and focus problems simultaneously, achieving a well-exposed, all-in-focus result.

Method of Image Fusion and Enhancement Using Mask Pyramid
We proposed an algorithmic approach using a mask pyramid to better localize the selection process. A new embedded system architecture that builds upon the Acadia ® II Vision Processor is proposed.
