Advanced Image Processing Package for FPGA-Based Re-Programmable Miniature Electronics

Nova Sensors produces miniature electronics for a variety of real-time digital video camera systems, including foveal sensors based on Nova’s Variable Acuity Superpixel Imager (VASI™) technology. An advanced imageprocessing package has been designed at Nova Sensors to re-configure the FPGA-based co-processor board for numerous applications including motion detection, optical, background velocimetry and target tracking. Currently, the processing package consists of 14 processing operations that cover a broad range of point- and area-applied algorithms. Flexible FPGA designs of these operations and re-programmability of the processing board allows for easy updates of the VASI ™ sensors, and for low-cost customization of VASI ™ sensors taking into account specific customer requirements. This paper describes the image processing algorithms implemented and verified in Xilinx FPGAs and provides the major technical performances with figures illustrating practical applications of the processing package

Location of the O-methyl groups in the O polysaccharide of Pseudomonas syringae pv. phaseolicola

Abstract The O-methylation pattern of the O polysaccharide (OPS) of the lipopolysaccharide of Pseudomonas syringae pv. phaseolicola GSPB 1552 was revealed by methylation (CD 3 I) analysis, Smith degradation, and NMR spectroscopy
