DCMTK is a collection of libraries and applications implementing large parts the DICOM standard. It includes software for examining, constructing and converting DICOM image files, handling offline media, sending and receiving images over a network connection, as well as demonstrative image storage and worklist servers.

ITK-SNAP is a tool for segmenting anatomical structures in medical images. It provides an automatic active contour segmentation pipeline, along with supporting a manual segmentation toolbox. ITK-SNAP has a full-featured UI aimed at clinical researchers.

This package implements a multi-dimensional spatial image data structure for scientific Python.

To facilitate:

• Multi-scale processing and analysis

• Registration

• Resampling

• Subregion parallel processing

• Coupling with meshes, point sets, and annotations

with scientific images, which are typically multi-dimensional with anisotropic sampling, this package provides a spatial-image data structure. In addition to an N-dimensional array of pixel values, spatial metadata defines the location of the pixel sampling grid in space time. It also labels the array dimensions. This metadata is easily utilized and carried through image processing pipelines.

AnsiLove is an ANSI and ASCII art to PNG converter, allowing to convert ANSI and artscene-related file formats into PNG images, supporting ANSI (.ANS), PCBoard (.PCB), Binary (.BIN), Artworx (.ADF), iCE Draw (.IDF), Tundra (.TND) and XBin (.XB) formats.

The Visualization Toolkit (VTK) is a C++ library for 3D computer graphics, image processing and visualization. It supports a wide variety of visualization algorithms including: scalar, vector, tensor, texture, and volumetric methods; and advanced modeling techniques such as: implicit modeling, polygon reduction, mesh smoothing, cutting, contouring, and Delaunay triangulation. VTK has an extensive information visualization framework, has a suite of 3D interaction widgets, supports parallel processing, and integrates with various databases on GUI toolkits such as Qt and Tk.

SimpleITK is an image analysis toolkit built on top of ITK. It provides a simplified interface to most of the image filters and the input/output and registration frameworks in ITK. It is written in C++ and provides bindings for interpreted languages. This package includes the C++, Python and R interfaces.

libansilove is a library for converting artscene file types to PNG images, including ANSI (.ANS) and many others. The library primarily serves to support the ansilove tool.

Image and video labeling tool supporting different shapes like polygons, rectangles, circles, lines, points and VOC/COCO export.

Scientific video can be packaged in various ways: familiar video formats like .AVI and .MOV, folders full of numbered images, or "stacks" of TIFF images. Each of these requires a separate Python module. And, once loaded, they have different methods for accessing individual images, looping through the images in bulk, accessing a specific range, or dealing with multidimensional files. PIMS can do all of these using a consistent interface, handling the differences between different inputs invisibly.

OpenCV is a library aimed at real-time computer vision, including several hundred computer vision algorithms. It can be used to do things like:

• image and video input and output

• image and video processing

• displaying

• feature recognition

• segmentation

• facial recognition

• stereo vision

• structure from motion

• augmented reality

• machine learning

This package includes the Python bindings for OpenCV, which are also known as the OpenCV-Python library.

VXL (the Vision-something-Libraries) is a collection of C++ libraries designed for computer vision research and implementation.

OpenColorIO, or OCIO, is a complete color management solution geared towards motion picture production, with an emphasis on visual effects and computer animation. It provides a straightforward and consistent user experience across all supporting applications while allowing for sophisticated back-end configuration options suitable for high-end production usage.

OCIO is compatible with the ACES and is LUT-format agnostic, supporting many popular formats.

The vtkdiff tool shall provide means of numerical comparison of different data arrays similar to those available in the numdiff software.

This package provide a graphical user interface (GUI) for the VIPS image processing library. It's a little like a spreadsheet: you create a set of formula connecting your objects together, and on a change nip2 recalculates.

Scan Tailor is an interactive post-processing tool for scanned pages. It performs operations such as page splitting, deskewing, adding/removing borders, and others. You give it raw scans, and you get pages ready to be printed or assembled into a PDF or DJVU file. Scanning, optical character recognition, and assembling multi-page documents are out of scope of this project.

Scan Tailer Advanced is a fork of Scan Tailer that merges Scan Tailor Featured and Scan Tailor Enhanced versions as well as including many more bug fixes.

VIPS is a demand-driven, horizontally threaded image processing library. It's particularly good at processing large images, working with colour, scientific analysis, and general research & development.

Compared to most image processing libraries VIPS needs little RAM and runs quickly, especially on machines with more than one CPU core. This is primarily due to its architecture which automatically parallelises the image workflows.

VXL (the Vision-something-Libraries) is a collection of C++ libraries designed for computer vision research and implementation.

Luminance HDR (formerly QtPFSGui) is a graphical user interface application that aims to provide a workflow for high dynamic range (HDR) imaging. It supports several HDR and LDR image formats, and it can:

• Create an HDR file from a set of images (formats: JPEG, TIFF 8bit and 16bit, RAW) of the same scene taken at different exposure setting;

• Save load HDR images;

• Rotate, resize and crop HDR images;

• Tone-map HDR images;

• Copy EXIF data between sets of images.

Catimg is a little program that prints images in the terminal. It supports JPEG, PNG and GIF formats.

Überzug is a command line util which draws images on terminals by using child windows. The advantages of using Überzug are:

• No race conditions as a new window is created to display images.

• Expose events will be processed, so images will be redrawn on switch workspaces.

• Tmux support (excluding multi pane windows).

• Terminals without the WINDOWID environment variable are supported.

• Chars are used as position - and size unit.

• No memory leak (/ unlimited cache).

lsix lists the images in a directory by displaying their thumbnails. Images are displayed in sixel graphics. lsix automatically detects terminal features and adapts the output to offer the highest quality possible. It can usually display non-bitmap graphics, including PDF. Your terminal should be sixel capable, like xterm -ti vt340.

Quick Image Viewer is a small and fast GDK/Imlib2 image viewer. Features include zoom, maxpect, scale down, fullscreen, slideshow, delete, brightness/contrast/gamma correction, pan with keyboard and mouse, flip, rotate left/right, jump/forward/backward images, filename filter and use it to set X desktop background.

pqiv is a GTK-3 based command-line image viewer with a minimal UI. It is highly customizable, can be fully controlled from scripts, and has support for various file formats including PDF, Postscript, video files and archives.

imv is a command line image viewer intended for use with tiling window managers. Features include:

• Native Wayland and X11 support.

• Support for dozens of image formats including:

  • PNG

  • JPEG

  • Animated GIFs
