چکیده
| We present two compact CMOS integrated circuits for computing the 2D local direction of motion of an image focused directly onto the chip. These circuits incorporate onboard photoreceptors and focal plane motion processing. With fully functional 14 13 and 12 13 implementations consuming less than 50 W per pixel, we conclude that practical pixel resolutions of at least 64 64 are easily achievable. Measurements characterizing the elementary 1D motion detectors are presented along with a discussion of 2D performance and example 2D motion vector elds. As an example application of the sensor, it is shown that the array as fabricated can directly compute the focus of expansion of a 2D motion vector eld.

Real-Time Analog VLSI Sensors for 2-D Direction of Motion
Optical ow elds are a primary source of information about the visual scene in technical and biological systems. In a step towards a system for real time scene analysis we have developed two new algorithms for the parallel computation of the direction of motion eld in 2-D. We have successfully implemented these algorithms in analog VLSI hardware such that all processing is performed in the focal...

In this work we present the rst working focal plane analog VLSI sensor for the spatially resolved computation of the 2-D motion eld based on temporal and spatial derivatives. Using an adaptive CMOS photoreceptor the temporal derivative and a function of the spatial derivative of the local light intensity are computed. By multiplying these values separately for both spatial dimensions a vector i...

متن کاملGains from diversification on convex combinations: A majorization and stochastic dominance approach
By incorporating both majorization theory and stochastic dominance theory, this paper presents a general theory and a unifying framework for determining the diversification preferences of risk-averse investors and conditions under which they would unanimously judge a particular asset to be superior. In particular, we develop a theory for comparing the preferences of different convex combination...
متن کاملImproved immunogenicity of tetanus toxoid by Brucella abortus S19 LPS adjuvant.
BACKGROUND Adjuvants are used to increase the immunogenicity of new generation vaccines, especially those based on recombinant proteins. Despite immunostimulatory properties, the use of bacterial lipopolysaccharide (LPS) as an adjuvant has been hampered due to its toxicity and pyrogenicity. Brucella abortus LPS is less toxic and has no pyrogenic properties compared to LPS from other gram negati...
