converts plain array images into multi-size representation (developments files)

The LiquidRescale (lqr) library provides a C/C++ API for performing non-uniform resizing of images by the seam-carving technique.

The library takes images in plain array format as input and converts them to a multi-size representation.

Following is a list of features:

* Areas in the image can be marked for preservation or discard * Once the image has been fully processed, the scaling can be done in real-time. In fact, the information can be saved and read out later without any further processing * The resizing is done with a single function which automatically performs all the necessary operations; it can also work in successive steps without wasting computational time * Possibility to tune the carving operation by letting the seams be less connected, or more rigid, or both * Can export and import the visibility map (the seams) * Other images can be attached and undergo the same carving process as the parent image * The automatic feature detection algorithm can be tuned by selecting among different energy gradient functions * Reports progress through a customizable interface * A signalling system permits to cleanly handle errors

The library implements the algorithm described in the paper "Seam Carving for Content-Aware Image Resizing" by Shai Avidan and Ariel Shamir, which can be found at

This package contains the development files.

Package version:0.1.0-1


LiquidRescale Library Examples

The examples directory contains two C++ programs,
liquidrescale and liquidrescale-basic. The first one
is a full-featured command-line application, while the
second one is just a minimalistic version of the first.

These programs are meant to be used as reference code,
and to integrate the documentation, and they are fully
commented. T
