A Biologically Inspired CMOS Image Sensor (Studies in Computational Intelligence)

A Biologically Inspired CMOS Image Sensor (Studies in Computational Intelligence), 9783642349003 (3642349005), Springer, 2012

Biological systems are a source of inspiration in the development of small autonomous sensor nodes. The two major types of optical vision systems found in nature are the single aperture human eye and the compound eye of insects. The latter are among the most compact and smallest vision sensors. The eye is a compound of individual lenses with their own photoreceptor arrays. The visual system of insects allows them to fly with a limited intelligence and brain processing power. A CMOS image sensor replicating the perception of vision in insects is discussed and designed in this book for industrial (machine vision) and medical applications.

The CMOS metal layer is used to create an embedded micro-polarizer able to sense polarization information. This polarization information is shown to be useful in applications like real time material classification and autonomous agent navigation. Further the sensor is equipped with in pixel analog and digital memories which allow variation of the dynamic range and in-pixel binarization in real time. The binary output of the pixel tries to replicate the flickering effect of the insect’s eye to detect smallest possible motion based on the change in state. An inbuilt counter counts the changes in states for each row to estimate the direction of the motion. The chip consists of an array of 128x128 pixels, it occupies an area of 5 x 4 mm2 and it has been designed and fabricated in an 180nm CMOS CIS process from UMC.

Encyclopedia of American Indian Wars 1492-1890

ABC Clio, 1997

Clashes between European powers and the indigenous peoples of the Americas began almost immediately upon the arrival of the first Europeans on the shores of the New World. Such conflict seems inevitable in retrospect, and perhaps it should have been expected at the outset as well. The great disparity between the two cultures,...

Cyber Situational Awareness: Issues and Research (Advances in Information Security)

Springer, 2009

Today, when a security accident occurs, the top three questions security administrators would ask are in essence: What has happened? Why did it happen? What should I do? Answers to the first two questions form the "core" of Cyber Situational Awareness. In addition, whether the last question can be well answered, is greatly dependent...

Data Structures: Abstraction and Design Using Java, 3rd edition

John Wiley & Sons, 2016

Our goal in writing this book was to combine a strong emphasis on problem solving and software design with the study of data structures. To this end, we discuss applications of each data structure to motivate its study. After providing the specification (interface) and the implementation (a Java class), we then cover case studies that use the...
