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 http://www.faculty.idc.ac.il/arik/imret.pdf
This package contains the development files.
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 more»
LQRCOLDEPTH(3) LqR library API reference LQRCOLDEPTH(3) NAME LqrColDepth - carver objects colour depth specification DESCRIPTION The default LqrCarver object constructor lqr_carver_new uses a colour depth of 8 bits per channel, and therefore its input must be an array of unsigned chars. However, the LqrCarver objects can handle images of grater c more»
LQRIMAGETYPE(3) LqR library API reference LQRIMAGETYPE(3) NAME LqrImageType - carver objects image type (colour model) specification DESCRIPTION The LqrCarver objects use knowledge about the image type they´re working on in order to compute correctly some quantities (e.g. the brightness) for the automatic feature detection. Image types are more»
