Im3 3 Docs.Pdf IM Image Representation, Storage, Capture and Processing Version 3.3 IM is a toolkit for Digital Imaging. IM is based on 4 concepts: Image Representation, Storage, Processing and Capture. The main goal of the library is to provide a simple API and abstraction of images for scientific applications. The most popular file formats are supported: TIFF, BMP, PNG, JPEG, GIF and AVI. Image representation includes scientific data types. About a hundred Image Processing operations are available. This work was developed at Tecgraf/PUC-Rio by means of the partnership with PETROBRAS/CENPES. Project Management: Antonio Escaño Scuri Tecgraf - Computer Graphics Technology Group, PUC-Rio, Brazil http://www.tecgraf.puc -rio.br/im Overview IM is a toolkit for Digital Imaging. IM is based on 4 concepts: Image Representation, Storage, Processing and Capture. Image Visualization is a task that it is left for a graphics library. It provides support for image capture, several image file formats and many image processing operations. The most popular file formats are supported: TIFF, BMP, PNG, JPEG, GIF and AVI. Image representation includes scientific data types (like IEEE floating point data) and attributes (or metadata like GeoTIFF and Exif tags). Animation, video and volumes are supported as image sequences, but there is no digital audio support. The main goal of the library is to provide a simple API and abstraction of images for scientific applications. The toolkit API is written in C. The core library source code is implemented in C++ and it is very portable, it can be compiled in Windows and UNIX with no modifications. New image processing operations can be implemented in C or in C++. IM is free software, can be used for public and commercial applications. IM has been used in Tecgraf for many theses and dissertations. Check the Publications in Tecgraf's web site http://www.tecgraf.puc -rio.br/ . Availability The library is available for several compilers : GCC and CC, in the UNIX environment Visual C++, Borland C++, Watcom C++ and GCC (Cygwin and MingW), in the Windows environment The library is available for several operating systems : UNIX (SunOS, IRIX, AIX, FreeBSD and Linux) Microsoft Windows NT/2K/XP Support The official support mechanism is by e-mail, using [email protected] -rio.br .

Some other files are available directly at the IM download folder: http://www.tecgraf.puc -rio.br/im/download/ Tecgraf/PUC-Rio Library Download Tips All the libraries were build using Tecmake . Please use it if you intend to recompile the sources. Tecmake can be found at http://www.tecgraf.puc -rio.br/tecmake .

Build Configuration Libraries and executables were built using speed optimization. In UNIX the dynamic libraries were NOT built with the -fpic parameter. In MacOS X the dynamic libraries are in bundle format. The source code along with the "config.mak" files for Tecmake are also available. The DLLs were built using the cdecl calling convention. This should be a problem for Visual Basic users. In Visual C++ we use the single thread C Run Time Library for static libraries and the multi thread C RTL for DLLs. Because this is the default in Visual Studio for new projects. In Visual C++ 8 both use the multi thread C RTL. Packaging The package files available for download are named according to the platform where they were build. In UNIX all strings are based in the result of the command "uname -a". The package name is a concatenation of the platform uname , the system major version number and the system minor version number. Some times a suffix must be added to complement the name. The default compiler is gcc, if the native compiler is used the name receive the suffix "cc". Binaries for 64-bits receive the suffix: "_64". In Linux when gcc is changed for the same uname in a new platform the major version number of the compiler is added as a suffix: "g3" for gcc 3 and "g4" for gcc 4. In Windows the platform name is the compiler and its major version number.

  • Finding an Appropriate Codec -.:: GEOCITIES.Ws
    1 Adobe Premiere Technical Guides Finding an appropriate codec Codecs are compression/decompression algorithms that are crucial for producing digital video and audio. Some codecs are more appropriate for certain kinds of work than others. Which codecs are available to you when editing digital video in Adobe® Premiere® 6.0 depends on your system and capture card. This choice is further constrained by the Editing Mode you choose in Premiere’s Project Settings dialog box. For example, in Windows the video codecs you can choose in Project Settings will be different if you choose Video for Windows as your Editing Mode than if you choose Quicktime. When you export digital video, the available codecs are determined by the File Type you choose in the Export Movie Settings dialog box. You can evaluate codecs by their intended uses, compression methods, and how they handle different kinds of pictures or sound. Video for Windows and QuickTime software are used for a wide range of video-related tasks, such as video conferencing, so they include many codecs which are not appropriate for video editing. Codecs intended for purposes other than video editing are identified in this section so that you can avoid them. If your video card provides hardware compression and its software is properly installed, its codec will appear in the Compressor menu in the Video Settings panel of the Project Settings dialog box. You can also access the codec in the dialog box for your video-capture hardware, which you can open by clicking the Video button in the Capture Settings panel of the Project Settings dialog box.

  • Multimedia and Computer Security Introduction to Multimedia
    Unit 8: Multimedia and Computer Security Introduction to Multimedia: • Newspaper and television are the common medium of mass communication. However, they differ in the way they present information to the user. • The information in a newspaper is presented as a combination of text, image, and graphics. This has a different impact on the user than the information presented on the television as a combination of image, photo, video, sound and music. • Similarly, talking over a telephone (using sound) has a different impact on the user, than, talking using the Internet telephone with a web camera (sound and photo) attached to it. • In other words, the same information when presented using different media has a different impact on the user. Or, we can say that the media used for presenting the information affects the way the user perceives and understands the information. • Multimedia is a combination of graphics, audio, text, animation, and video using the computer. Multimedia-Definition: • The word multimedia consists of two words—multi and media. The word multi means many and the word media (plural of medium) are the means through which information is shared. • Multimedia is the field concerned with the computer-controlled integration of text, graphics, drawings, still and moving images (Video), animation, audio, and any other media where every type of information can be represented, stored, transmitted and processed digitally. • A Multimedia Application is an Application which uses a collection of multiple media sources e.g. text, graphics, images, sound/audio, animation and/or video. • Newspaper, radio, television and films are some of the earliest and traditional means of mass communication that use mass media.

  • Video Kompressioon
    Multimeedium, videokompressioon Video kompressioon Praegu ei suuda olemasolevad arvutid ja arvutivõrgud kompressioonita, täisvärvidega kõrge- kvaliteedilise digitaalvideoga midagi teha. Digitaalvideo kasutamine arvutis eeldab madalama kvaliteediga videot, mis annab väiksema hulga tihendamata infot ja muidugi sellele lisaks veel kompressiooni. Video töötlemine arvutis eeldab igal juhul kompressiooni kasutamist. Enamasti on täiesti vastuvõetav vähendada andmete hulka kasutades väiksemat kaadri suurust harva ka väiksemat kaadrisagedust. Näiteks video, mille kaadri suurus on 2 korda kitsam ja madalam kui VGA pilt (320 X 240) saavutab 5,3 kordse andmemahu vähenemise juba kompressioonita. Mitmed koodekid (codec), näiteks DivX, eeldavad kaadri suurust 352 X 288 pikselit, mis annab juba umbes 4-kordse kokkuhoiu. Kummagi näite korral pole aga võimalik seda videot minutite pikkuselt CD-le salvestada. Vajalik on kompressiooni kasutamine. Tavaliselt nõuab parem kompressioonitehnoloogia suuremaid kulutusi nii video tegija kui ka tarbija poolt. Kompressiooni puhul määratavad parameetrid Kompressioonimeetodi häälestamisel saab videokoodekitel lisaks bitikiirusele (bitrate) määrata veel mitmeid parameetreid, näiteks heliportsjonite vahele jäävate kaadrite arvu ja nn võtmekaadrit (key frame). Sageli on videoklipi muutused kaadrist kaadrisse minimaalselt väikesed. Sellistel juhtudel on ökonoomsuse seisukohalt kasulik terviklike kaadrite asemel salvestada vaid need andmed, mis muutuvad. Saab määrata, kui sageli esinevad nn võtmekaadrid (key frame), mis salvestatakse tervikuna ja mille suhtes järgmiste kaadrite erinevusi salvestatakse. Võtmekaadri valikul on omad piirangud, mida suurem on nende vahe, seda suuremad muudatused võivad vahepeal toimuda ja liiga suure vahe korral on risk, et kaotame osa muudatustest. Kui videofaili on edaspidi kavas taasesitada CD-ROMilt, siis saab määrata, et kaadrid peavad olema “täis topitud” (padded). “Täis toppimine” (padding) lisab kaadritele baite, et kõik nad oleksid täpselt ühe suurusega.

  • A Guide for File Extensions
    A Guide to File Extensions You will find attached a list of the extensions you might find on your pc, floppy or the internet. The list includes the extension, description, whether it's text, and the likely programs to use to view the contents. Because I included the internet there are unix, mac, … files included - where possible I've include PC programs which will read them. Some of the programs will only read or write or only accept certain variants of the file so even though a program is listed it doesn't mean it will read your particular version of the file. I have done my best to keep this accurate but this is supplied on a all care but no responsibility basis.
