About

From the project README ·

An image processing library, based on the image library.

API documentation

Goals

A performant, well-tested, well-documented library with a consistent API, suitable for use as the basis of computer vision applications or graphics editors.

Non-goals

Maximum genericity over image storages or formats, or support for higher-dimensional images.

Color Space

Functions in this library implicitly assume that pixels colors are stored in a linear color space like RGB as opposed to a non-linear color space such as sRGB.

If you are not familiar with gamma correction then this article contains an introduction and examples of color artefacts resulting from not using linear color spaces.

Parallelism

This library provides both single-threaded and multi-threaded variations of several functions by using rayon.

Depending on image size and the amount of work performed per pixel the parallel versions may not always be faster - we recommend benchmarking for your specific use-case.

Crate Features

Default Features
  • rayon: enables multi-threaded versions of several functions
  • text: enables text drawing
  • fft: enables phash and other functions that depend on the rustfft crate
Read the full README
Optional Features

  • display-window: enables the displaying of images (using imageproc::window) with sdl2. SDL2 must be installed on the system before building with this feature. For example:

    # Ubuntu/Debian
sudo apt install libsdl2-dev

# macOS
brew install sdl2

    On Windows, install SDL2 and ensure its library directory is available to the linker and its DLL directory is included in PATH.

Why FeaturedIt passes every Featured gate.

What it meets

  • It has 161 active dependents and 113 new dependents in 365 days. Featured needs 11 active dependents or 9 new dependents in 365 days.
  • Active dependents are at 100% of their peak. Featured needs at least 50%.
  • Docs are present. The release commit or a manifest ties the crate to the repository.
  • No vulnerability advisory stays unpatched past the grace window. At least one version is neither a prerelease nor 0.0.x.
  • The last activity is on 31 Oct 2026, 9 days ago. The rules expect an update within 560 days. Dormancy rule

Exact rules: Featured library. The check on applied thresholds version 9.

Every rule outcome, as the check records it
  • expected-interval: version 0.27.0 base 140, doubled for 1165048 downloads per month, doubled for 161 active users: E = 560 days
  • dormancy: last activity 2026-10-31, 9 days ago, E = 560: active
  • featured: featured: active_users 161, new_adopters 112.5, former_glory 1
