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.

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.

ParaView is a VTK-based, parallel data analyzer and visualizer which allows exploring data interactively in 3D or programmatically.

The Insight Toolkit (ITK) is a toolkit for N-dimensional scientific image processing, segmentation, and registration. Segmentation is the process of identifying and classifying data found in a digitally sampled representation. Typically the sampled representation is an image acquired from such medical instrumentation as CT or MRI scanners. Registration is the task of aligning or developing correspondences between data. For example, in the medical environment, a CT scan may be aligned with a MRI scan in order to combine the information contained in both.

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.

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.

ytfzf is a POSIX script that helps you find PeerTube or YouTube videos without requiring API and opens/downloads them using mpv/ytdl.

gpicview is a lightweight GTK+ 2.x based image viewer. It is the default image viewer on LXDE desktop environment.

qView is a Qt image viewer designed with visually minimalism and usability in mind. Its features include animated GIF controls, file history, rotation/mirroring, and multithreaded preloading.

Swayimg is a fully customizable and lightweight image viewer for Wayland based display servers. It supports the most popular image formats (JPEG, JPEG XL, PNG, GIF, SVG, WebP, HEIF/AVIF, AV1F/AVIFS, TIFF, EXR, BMP, PNM, TGA, QOI, DICOM, Farbfeld). It has fully customizable keyboard bindings, colors, and many other parameters. It also supports loading images from files and pipes, and provides gallery and viewer modes with slideshow and animation support. It also includes a Sway integration mode: the application creates an overlay above the currently active window, which gives the illusion that you are opening the image directly in a terminal window.

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.

xzgv is a fast image viewer that provides extensive keyboard support.

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).

qpageview provides a page based document viewer widget for Qt and PyQt. It has a flexible architecture potentionally supporting many formats. Currently, it supports SVG documents, images, and, using the Poppler-Qt5 binding, PDF documents.

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.

The hydrus network client is an application written for internet-fluent media nerds who have large image/swf/webm collections. It browses with tags instead of folders, a little like a booru on your desktop. Advanced users can share tags and files anonymously through custom servers that any user may run. Everything is free and privacy is the first concern.

Nomacs is a simple to use image lounge featuring semi-transparent widgets that display additional information such as metadata, thumbnails and histograms. It is able to browse images compressed archives and add notes to images.

Nomacs includes image manipulation methods for adjusting brightness, contrast, saturation, hue, gamma, and exposure. It has a pseudo color function which allows creating false color images. A unique feature of Nomacs is the synchronization of multiple instances.

Chafa is a command-line utility that converts all kinds of images, including animated GIFs, into ANSI/Unicode character output that can be displayed in a terminal.

feh is an X11 image viewer aimed mostly at console users. Unlike most other viewers, it does not have a fancy GUI, but simply displays images. It can also be used to set the desktop wallpaper. It is controlled via commandline arguments and configurable key/mouse actions.

Geeqie is a lightweight GTK+ based image viewer for Unix like operating systems. It features: EXIF, IPTC and XMP metadata browsing and editing interoperability; easy integration with other software; geeqie works on files and directories, there is no need to import images; fast preview for many raw image formats; tools for image comparison, sorting and managing photo collection. Geeqie was initially based on GQview.

PIXterm shows images directly in your terminal, recreating the pixels through a combination of ANSI character background color and the unicode lower half block element. It supports JPEG, PNG, GIF, BMP, TIFF and WebP.

MComix is a customizable image viewer that specializes as a comic and manga reader. It supports a variety of container formats including CBZ, CB7, CBT, LHA.

For PDF support, install the mupdf package.
