  • The Application of Image Processing Software for Analysis of Roentgenograms
    92 X Research and Teaching of Physics in the Context of University Education Nitra, June 5 and 6, 2007 THE APPLICATION OF IMAGE PROCESSING SOFTWARE FOR ANALYSIS OF ROENTGENOGRAMS Jan Sedláček Abstract Till this time the roentgenograms (also the electronic ones) are evaluated mostly visually. There are many possibilities for evaluation of digital roentgenograms. The aim of our effort is the betterment of the visual readability of roentgenograms for the accurate determination of the eventual seed damage. There are some possibilities to improve the gained electronic image with using PC. We can use either special PC programs or readily available software for image processing. One of the popular special PC programs is the software from the system of Lucia. It is used in life science, criminalistics, materials, or quality controls applications. The function of the “edges detection” is applied for the findings of the eventual seed damage. A very good job for image processing can made readily available PC programs. The freeware of Neat Image is one of the best programs for noise rejection. There is needed to sharpen the image by elevation of contrast and set-up of brightness past noise reduction. We can use Adobe Photoshop or XnView programs for that purpose. The excellent universal freeware for image processing is ImageJ. It uses the functions of median filter for noise reduction, contrast enhancing and edges detection. Keywords: visual readability, image processing software, improvement of images, roentgenogram, Lucia, Neat Image, Adobe Photoshop, XnView, ImageJ. Introduction The digital roentgenogram is made by special sensor, where the space arranged CCD matrix of elements makes the image, which is saved as a digital file for the next process in computer.

  • Imagemagick V6.8.7-3 - Training Material | WP3
    ImageMagick v6.8.7-3 - Training Material | WP3 Author: Sebastian Kirch (IAIS) Tool Description ImageMagick is a software suite to create, edit, compose, or convert bitmap images. It can read and write images in a variety of formats (over 100) including DPX, EXR, GIF, JPEG, JPEG-2000, PDF, PhotoCD, PNG, Postscript, SVG, and TIFF. Use ImageMagick to resize, flip, mirror, rotate, distort, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bézier curves. ImageMagick is free software delivered as a ready-to-run binary distribution or as source code that you may use, copy, modify, and distribute in both open and proprietary applications. It is distributed under the Apache 2.0 license. Scanned document images often need to be optimized in order to enhance their contrast or to scale them to a certain size. This step is usually part of the post-processing workflow where images are prepared for visual presentation or they are analyzed using OCR and text processing software. By integrating image manipulation software such as ImageMagick into the post- processing workflow, images can be automatically enhanced using all the operations and features that the software has to offer. They can be resized, optimized or otherwise edited in one single step without any manual intervention. System Requirements Operating System Windows, Linux, Mac OS X, iOS Hardware Dependencies - Software Dependencies - Non-technical Requirements ImageMagick does not have a graphical user interface (GUI) and therefore requires some basic knowledge on how to use and execute the command-line programs. Installation Files Binary releases can be downloaded from the ImageMagick website at http://www.imagemagick.org/script/binary-releases.php.

    Creative Software Useful Linux Commands Software Overview Useful Linux Commands Ghostscript (Link) RGB to CMYK Conversion This command will convert PDFs in the RGB color space, such as those created in Inkscape, to CMYK for print. Within the terminal navigate to the file directory and replace out.pdf with the desired output CMYK file name and in.pdf with the existing RGB file: gs -o out.pdf -sDEVICE=pdfwrite -dUseCIEColor -sProcessColorModel=DeviceCMYK - sColorConversionStrategy=CMYK -dEncodeColorImages=false - sColorConversionStrategyForImages=CMYK in.pdf Compress CMYK File This command will reduce the dpi of a PDF to 300 (and possibly other compression). This is useful after converting PDFs to CMYK using the prior command because they can be very large. gs -dBATCH -dNOPAUSE -q -sDEVICE=pdfwrite -dPDFSETTINGS=/prepress -sOutputFile=out.pdf in.pdf Merge and Compress PDF Files This command will merge two PDF files and reduce the dpi to 300. This is useful when generating PDFs in Inkscape. gs -dBATCH -dNOPAUSE -q -sDEVICE=pdfwrite -dPDFSETTINGS=/prepress -sOutputFile=out.pdf in1.pdf in2.pdf Convert PNG's to JPG's in a sub-directory Inkscape only exports files in PNG format. This is a simple command to convert them those PNG files to JPG (with default compression?) using Imagemagick to a subdirectory called Exported_JPGs. Run this command inside of the directory of the PNG files. mogrify -path Exported_JPGs -format jpg *.png Software Overview We use the following software during the course of our work. All of these applications are Free and Open Source Software (FOSS). Operating Systems Solus - A GNU/Linux based operating system with great performance and stability.

  • Chapter 11 Graphics and Site Production
    Chapter 11 Graphics and Site Production Site production is concerned with actually creating all the components that will ¯t together and form the desired site. Typically a project team has already made substantial progress and completed the formulation of these items: ² Text-only site with structure, navigation system, typical pages, ¯ll-out forms, and textual content. ² Look and feel of site: font, spacing, color, and layout. ² Design of graphical elements: site entry, rollovers, graphics and images. Based on the graphical designs, image processing tools such as Photoshop can be used to produce the desired image ¯les are ready to drop into the designated spaces in the layout. This is what we call graphics production. Graphics production involves the manufacture of various elements such as navigation bars, hand-drawn images, photographs, charts, illustration and so on. These elements are referred to as the \¯nal art." This is normally considered a fairly mechanical procedure, one in which you follow speci¯c steps to produce the graphical elements needed. With graphics production done, the project team is ready to produce the site. Figure 11.1 shows an overview of the site production process. The three boxes on the third row in this ¯gure constitute the input to the production process. Central to the production e®ort is an 513 514 CHAPTER 11. GRAPHICS AND SITE PRODUCTION Integrated Development Environment (IDE) such as Macromedia Dreamweaver. The IDE provide an e®ective visual environment to create layout grids, drop in graphics and text, install rollovers, and adjust HTML and styles. The IDE can then generate HTML page templates, style sheets (CSS), and Javascript code.

  • Graphicxpsd Package
    graphicxpsd Package Munehiro Yamamoto 2021/01/07 v1.2 Abstract This package provides Adobe Photoshop Data format (PSD) support for graphicx package with sips (Darwin/macOS)/magick (ImageMagick) command. 1 Motivation graphicx package supports already many graphics image formats as bellow. • non-vector formats: jpg, png, bmp, and so on • PostScript-style formats: eps, ps • PDF-style formats: pdf, ai However, it currently does not support Adobe Photoshop Data format (PSD). Against that, we developed the graphicxpsd package to support PSD format via PSD-to-PDF conversion with two image converters. • sips: pre-installed command in Darwin/macOS • magick: bundled command in ImageMagick 2 Loading graphicxpsd Package Load graphicxpsd package after loading graphicx package. \usepackage{graphicx} \usepackage[<options>]{graphicxpsd} The list of available options is the following. • dvipdfmx, xetex, pdftex, luatex: supported driver options; You can also give specific driver option from global option. • sips (default), magick (same as imagemagick), convert1: supported im- age converters; 1 – Darwin/macOS users do not have to do anything unless you choose ImageMagick as PSD-to-PDF converter. – If you use ImageMagick 7, you may choose magick. – If you should use ImageMagick 6 or lower version, you just choose convert. • cache=true: supports to include cached images for all PSD files. If there does not exist the cached image for a PSD file, graphicxpsd attempts PSD- to-PDF conversion of the PSD file. 3 Example Typeset the following LATEX document with LuaTEX enabling the shell escape, that is, run lualatex -shell-escape. %#!lualatex -shell-escape \documentclass[luatex]{article}%%set luatex driver as global option \usepackage{graphicx} \usepackage{graphicxpsd} \begin{document} \includegraphics{tigerpsdfmt.psd} \end{document} Then, the result is as below.

  • Digital Photo Editing
    Digital Photo Editing Digital Photo Editing There are two main catagories of photo editing software. 1. Photo Organizers - Programs that help you find your pictures. May also do some editing, and create web pages and collages. Examples: Picasa, XNView, ACDsee, Adobe Photoshop Elements 2. Photo Editors - Work on one picture file at a time. Usually more powerful editing features. Examples: Adobe Photoshop, Gimp, Paint.Net, Corel Paint Shop Photo Organizers Organizers tend to have a similar look and functionality to each other. Thumb nail views, a directory tree of your files and folders, and a slightly larger preview of the picture currently selected. A selection of the most used editing tools, and batch editing for making minor corrections to multiple pictures at once. The ability to create slide shows, contact sheets, and web pages are also features you can expect to see. XNView Picasa ACDsee Some of the editing features included in Photo Organizer software are: Red Eye Reduction, Rotate, Resize, Contrast, Color Saturation, Sharpen Focus and more. Many of these can be done in batch mode to as many pictures as you select. Picasa has added Picnik to it's tool set allowing you to upload your photo to the Picnik website for added editing features. Here is an example of Redeye removal in Picasa. Crop, Straighten, and Fill Light are often needed basic fixes. Saving and converting your picture file.
