Abstract:
The importance of embedded applications on image and video processing, communication and cryptography domain has been taking a larger space in current research era. Improvement of pictorial information for betterment of human perception like deblurring, de-noising in several fields such as satellite imaging, medical imaging etc are renewed research thrust. Specifically we would like to elaborate our experience on the significance of computer vision as one of the domains where hardware implemented algorithms perform far better than those implemented through software. So far embedded design engineers have successfully implemented their designs by means of Application
Specific Integrated Circuits (ASICs) and/or Digital Signal Processors (DSP), however with the advancement of VLSI technology a very powerful hardware device namely the Field Programmable
Gate Array (FPGA) combining the key advantages of ASICs and DSPs was developed which have the possibility of reprogramming making them a very attractive device for rapid prototyping.
Communication of image and video data in multiple FPGA is no longer far away from the thrust of secured transmission among them, and then the relevance of cryptography is indeed unavoidable.
This paper shows how the Xilinx hardware development platform as well Mathwork’s Matlab can be
used

    In the consumer driven society that we live in, major manufacturers are always looking for ways to produce effective marketing so that the general public will buy their product. To relate to the public in these advertisements, advertisers create an image using a subject, a number of objects, unique placement of the objects, and specific color and lighting. Advertisers will also use the gaze, pose and mouth position of the models in their advertisements to market their product successfully.…

    The use of imagery is one of the most commonly used techniques in poetry. Poets create an image in one’s mind through descriptive language, similes, and rhythm. Their words flow off the page to appeal to our senses. Those who have perfected this art let us see exactly what they see in their minds. William Carol Williams, David Solway, and Amy Lowell’s poems are perfect examples of imagery.…

    MATLAB. One kind of the computing languages is MATLAB created by MathWorks, which allows manipulation of matrix, plotting of functions, implementation of algorithms, creation of interfaces, and interfacing with platforms written in other languages. This type of scientific computing application has significant advantages among other software simulations which can be seen by faster response for different technical problems and relatively easier to use (Moore, 2012). In addition, MATLAB is optimized for matrix calculations and regularly updated. Thus MATLAB extensively spread and used by control engineers for analysis and design of projects.…

    FPGAs contain programmable logic components called "logic blocks", and a hierarchy of reconfigurable interconnects that allow the blocks to be "wired together" somewhat like many (changeable) logic gates that can be inter-wired in (many) different configurations. Logic blocks can be configured to perform complex combinational functions, or merely simple logic gates like AND and XOR. In most FPGAs, the logic blocks also include memory elements, which may be simple flip-flops or more complete blocks of…

    A field-programmable gate array (FPGA) is an integrated circuit designed to be configured by a customer or a designer after manufacturing—hence "field-programmable". The FPGA configuration is generally specified using a hardware description language (HDL), similar to that used for an application-specific integrated circuit (ASIC) (circuit diagrams were previously used to specify the configuration, as they were for ASICs, but this is increasingly rare). Contemporary FPGAs have large resources of logic gates and RAM blocks to implement complex digital computations. As FPGA designs employ very fast IOs and bidirectional data buses it becomes a challenge to verify correct timing of valid data within setup time and hold time. Floor planning enables resources allocation within FPGA to meet these time constraints. FPGAs can be used to implement any logical function that an ASIC could perform. The ability to update the functionality after shipping, partial re-configuration of a portion of the design and the low non-recurring engineering costs relative to an ASIC design (notwithstanding the generally higher unit cost), offer advantages for many applications.…

    One photograph depicts a group of rural men. All of them are looking at the camera and some of them are seated and others stood on or near a huge tree’s trunk. Few of them hold on their hands work equipment such as axs which help them to cut down and dismember tree’s trunk. Thus, this single picture illustrate theme of work shown by piece of wood around and work equipments. Another element that emerges from this picture is the exploitation of wood as a daily activity. In addition to logging, the photo illustrate the old Northwest society and the beauty of its nature. Although the photo seems to emphasize the exploitation of wood as a natural resource and wealth, it also shows us trees cutted, dirtiness, and men with axes on hand that characterize the work of people who live in a forest area.…

    Computer scientists have always been challenged in their bid to implement real time image processing on serial processors. These difficulties have always been brought up by image properties such as large data sets, and complex operations that need to be performed on the image. In real time processing, 25 frames are witnessed every second. This alone contributes to redundancy and also adds to the slowing down of processing brought about by overheads of retrieval and storing of picture ingredients. In order to counteract the limitations that come with real time image processing, the use of field programmable gate arrays was discovered. FPGA have as a result brought about better revival in this industry (Hutchings, B. and Villasenor, J. pp. 67-84, Sep 1998). FPGA is an integrated circuit if numerous logic cells that are interconnected together for mutual coordination. Before the invention of FPGA, scientists always used fixed circuit of gates but this has numerous disadvantages in line with rigidity and expense. The coming of FPGA was welcomed with great gratitude and soon, these logic cells…

    The Fast Fourier transform (FFT) is one of the most important algorithms in the field of digital signal processing. It is used to calculate the discrete Fourier transform (DFT) efficiently. In order to meet the high performance and real-time requirements of modern applications, hardware designers have always tried to implement efficient architectures for the computation of the FFT. In this context, pipelined hardware architectures are widely used, because they provide high throughputs and low latencies suitable for real time, as well as a reasonably low area and power consumption.…
