VIPS is an open source image processing software package.〔 (Martinez, K. and Cupitt, J. (2005) VIPS ― a highly tuned image processing software architecture. In Proceedings of IEEE International Conference on Image Processing 2, pp. 574-577, Genova )〕〔Cupitt, J. and Martinez, K. (1996) VIPS: An image processing system for large images, Proc. SPIE, vol. 2663, pp. 19--28 (full paper )〕 It is particularly good with large images, works with multi-core processors, working with colour, scientific analysis and general research & development. It was developed during and is the product of several European research projects (VASARI, MARC, ACOHIR, Viseum) which were primarily about Imaging art,〔Cupitt, J. and Martinez, K. (1994) Image processing for Museums. In: pp. 133-147, John Wiley. ISBN 0-471-93941-2〕 but which demanded a new approach to image processing. Compared to most image processing libraries VIPS needs little RAM and runs quickly, especially on machines with more than one CPU. This is primarily due to its architecture which automatically parallelises the image workflows.〔http://www.vips.ecs.soton.ac.uk/index.php?title=Speed_and_Memory_Use〕 The software has two main parts: libvips is the image-processing library and nip2 is the graphical user-interface. The GUI aims to be about half-way between Photoshop and Excel. It is not designed for tasks such as retouching photographs, but more useful for the many other imaging tasks that programs like Photoshop are used for. Both work on Linux, Unix, Windows (NT, 2k, XP, Vista, Win7) and Apple Mac OS (OS 10.2 and later).〔(Cupitt, J., Boobis, A., Jones, H. (2007) Automating image analysis with VIPS, Poster presentation, Hounsfield Memorial Lectures on Medical Imaging )〕 VIPS is currently used in MediaWiki and hence by WikiPedia itself in the (VipsScaler ) extension. This speeds up and extends image handling. VIPS is a standard package for many Linux distributions 〔Debian VIPS package http://packages.qa.debian.org/v/vips.html〕〔Ubuntu VIPS package http://packages.ubuntu.com/hardy/libvips-tools〕 〔Fedora https://admin.fedoraproject.org/pkgdb/acls/name/nip2〕〔Mint http://community.linuxmint.com/software/view/nip2〕 ==Software Design== Most of libVIPS is written in C. However, there are Python and C++ libraries which can use it. image:vipspartials.png VIPS processes images in small portions (rectangles or groups of lines) and groups of operations are automatically run by separate threads. This makes the processing parallel because modern systems can run the threads on different cores. It also means that image intermediates are small and can easily be stored in RAM. This is how multi-GB sized images can be processed on machines efficiently.〔http://www.vips.ecs.soton.ac.uk/index.php?title=How_it_works〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「VIPS (software)」の詳細全文を読む スポンサード リンク
