Applications of Digital Image Processing in Real Time World INTERNATIONAL JOURNAL OF SCIENTIFIC & TECHNOLOGY RESEARCH VOLUME 8, ISSUE 12, DECEMBER 2019 ISSN 2277-8616 Applications Of Digital Image Processing In Real Time World B.Sridhar Abstract :-- Digital contents are the essential kind of analyzing, information perceived and which are explained by the human brain. In our brain, one third of the cortical area is focused only to visual information processing. Digital image processing permits the expandable values of different algorithms to be given to the input section and prevent the problems of noise and distortion during the image processing. Hence it deserves more advantages than analog based image processing.

Different land cover types in an image can be discriminated using some image classification algorithms using spectral features, i.e. the (a) (b) brightness and "colour" information contained in each pixel. The classification can be "supervised" or" unsupervised" and the results are highlighted in figure 4. In supervised classification, the spectral features of some areas of known land cover types are extracted from the image. These areas are known as the "training areas". Every pixel in the whole image is then classified as belonging to one of the classes depending on how close its spectral features are to the spectral features of the training areas. In unsupervised (c) (d) classification, the computer program automatically groups Fig: 2 (a) Input Image, (b) Segmented image, (c) Image the pixels in the image into separate clusters, depending on after crop detection and (d) Weed identification. their spectral features. Each cluster will then be assigned a land cover type by the analyst. 2.2 Multimedia Security Development of multimedia innovation in the present era, the digital content has allowed freely to spreadout.

  • Information- Processing Conceptualizations of Human Cognition: Past, Present, and Future
    13 Information- Processing Conceptualizations of Human Cognition: Past, Present, and Future Elizabeth E Loftus and Jonathan w: Schooler Historically, scholars have used contemporary machines as models of the mind. Today, much of what we know about human cognition is guided by a three-stage computer model. Sensory memory is attributed with the qualities of a computer buffer store in which individual inputs are briefly maintained until a meaningful entry is recognized. Short-term memory is equivalent to the working memory of a computer, being highly flexible yet having only a limited capacity. Finally, long-term memory resembles the auxiliary store of a computer, with a virtually unlimited capacity for a variety of information. Although the computer analogy provides a useful framework for describing much of the present research on human cogni- tion, it is insufficient in several respects. For example, it does not ade- quately represent the distinction between conscious and non-conscious thought. As an alternative. a corporate metaphor of the mind is suggested as a possible vehiclefor guiding future research. Depicting the mind as a corporation accommodates many aspects of cognition including con- sciousness. In addition, by offering a more familiar framework, a corpo- rate model is easily applied to subjective psychological experience as well as other real world phenomena. Currently, the most influential approach in cognitive psychology is based on analogies derived from the digital computer. The information processing approach has been an important source of models and ideas but the fate of its predecessors should serve to keep us humble concerning its eventual success. In 30 years, the computer-based information processing approach that cur- rently reigns may seem as invalid to the humlln mind liSthe wax-tablet or tl'kphOlIl' switchhoard mmkls do todoy.

This article is published online with Open Access by IOS Press and distributed under the terms of the Creative Commons Attribution Non-Commercial License 4.0 (CC BY-NC 4.0). doi:10.3233/SHTI190113 Distributed Cognition: Understanding Complex Sociotechnical Informatics Dominic FURNISSa,1, Sara GARFIELD b, c, Fran HUSSON b, Ann BLANDFORD a and Bryony Dean FRANKLIN b, c a University College London, Gower Street, London; UK b Imperial College Healthcare NHS Trust, London; UK c UCL School of Pharmacy, London; UK Abstract. Distributed cognition theory posits that our cognitive tasks are so tightly coupled to the environment that cognition extends into the environment, beyond the skin and the skull. It uses cognitive concepts to describe information processing across external representations, social networks and across different periods of time. Distributed cognition lends itself to exploring how people interact with technology in the workplace, issues to do with communication and coordination, how people’s thinking extends into the environment and sociotechnical system architecture and performance more broadly. We provide an overview of early work that established distributed cognition theory, describe more recent work that facilitates its application, and outline how this theory has been used in health informatics. We present two use cases to show how distributed cognition can be used at the formative and summative stages of a project life cycle. In both cases, key determinants that influence performance of the sociotechnical system and/or the technology are identified. We argue that distributed cognition theory can have descriptive, rhetorical, inferential and application power.

  • Augmented Cognition for Bioinformatics Problem Solving
    Augmented Cognition for Bioinformatics Problem Solving Olga Anna Kuchar and Jorge Reyes-Spindola Michel Benaroch Pacific Northwest National Laboratory Center for Creation and Management of Digital P.O. Box 999, 902 Battelle Blvd. Ventures Richland, WA, 99352 Martin J. Whitman School of Management Syracuse {olga.kuchar, jorge.reyes.spindola}@pnl.gov University, Syracuse, NY, 13244 mbenaroc@syr.edu Abstract We describe a new computational cognitive model that has been developed for solving complex problems in bioinformatics. This model addresses bottlenecks in the information processing stages inherent in the bioinformatics domain due to the complex nature of both the volume and type of data and the knowledge required in solving these problems. There is a restriction on the amount of mental tasks a bioinformatician can handle when solving biology problems. Bioinformaticians are overwhelmed at the amount of fluctuating knowledge, data, and tools available in solving problems, but to create an intelligent system to aid in this problem-solving task is difficult because of the constant flux of data and knowledge; thus, bioinformatics poses challenges to intelligent systems and a new model needs to be created to handle such problem-solving issues. To create a problem-solving system for such an environment, one needs to consider the scientists and their environment, in order to determine how humans can function in such conditions. This paper describes our experiences in developing a complex cognitive system to aid biologists in knowledge discovery. We describe the problem domain, evolution of our cognitive model, the model itself, how this model relates to current literature, and summarize our ongoing research efforts.

Updated version October 2000, with corrections in footnote of section 4.2 Recommendations of the International Medical Informatics Association (IMIA) on Education in Health and Medical Informatics International Medical Informatics Association, Working Group 1: Health and Medical Informatics Education Abstract: The International Medical Informatics Association (IMIA) agreed on international recommendations in health informatics / medical informatics education. These should help to establish courses, course tracks or even complete programs in this field, to further develop existing educational activities in the various nations and to support international initiatives concerning education in health and medical informatics (HMI), particularly international activities in educating HMI specialists and the sharing of courseware. The IMIA recommendations centre on educational needs for health care professionals to acquire knowledge and skills in information processing and information and communication technology. The educational needs are described as a three-dimensional framework. The dimensions are: 1) professionals in health care (physicians, nurses, HMI professionals, ...), 2) type of specialisation in health and medical informatics (IT users, HMI specialists) and 3) stage of career progression (bachelor, master, ...). Learning outcomes are defined in terms of knowledge and practical skills for health care professionals in their role (a) as IT user and (b) as HMI specialist. Recommendations are given for courses/course tracks in HMI as part of educational programs in medicine, nursing, health care management, dentistry, pharmacy, public health, health record administration, and informatics/computer science as well as for dedicated programs in HMI (with bachelor, master or doctor degree).

While cognitive science is considered as “thinking about the process of thinking”, cognitive bioinformatics strives to capture the process of thought and analysis as applied to the challenging intersection of diverse fields such as biology, informatics, and computer science collectively known as bioinformatics. Ten years ago cognitive bioinformatics was introduced as a model of the analysis performed by scientists working with molecular biology and biomedical web resources. At present, the concept of cognitive bioinformatics can be examined in the context of the opportunities represented by the information “data deluge” of life sciences technologies. The unbalanced nature of accumulating information along with some challenges poses currently intractable problems for researchers.

  • What Are Computational Neuroscience and Neuroinformatics? Computational Neuroscience
    Department of Mathematical Sciences B12412: Computational Neuroscience and Neuroinformatics What are Computational Neuroscience and Neuroinformatics? Computational Neuroscience Computational Neuroscience1 is an interdisciplinary science that links the diverse fields of neu- roscience, computer science, physics and applied mathematics together. It serves as the primary theoretical method for investigating the function and mechanism of the nervous system. Com- putational neuroscience traces its historical roots to the the work of people such as Andrew Huxley, Alan Hodgkin, and David Marr. Hodgkin and Huxley's developed the voltage clamp and created the first mathematical model of the action potential. David Marr's work focused on the interactions between neurons, suggesting computational approaches to the study of how functional groups of neurons within the hippocampus and neocortex interact, store, process, and transmit information. Computational modeling of biophysically realistic neurons and dendrites began with the work of Wilfrid Rall, with the first multicompartmental model using cable theory. Computational neuroscience is distinct from psychological connectionism and theories of learning from disciplines such as machine learning,neural networks and statistical learning theory in that it emphasizes descriptions of functional and biologically realistic neurons and their physiology and dynamics. These models capture the essential features of the biological system at multiple spatial-temporal scales, from membrane currents, protein and chemical coupling to network os- cillations and learning and memory. These computational models are used to test hypotheses that can be directly verified by current or future biological experiments. Currently, the field is undergoing a rapid expansion. There are many software packages, such as NEURON, that allow rapid and systematic in silico modeling of realistic neurons.
