How To Install liblqr-1-0-dbg on Debian 9

In this tutorial we learn how to install liblqr-1-0-dbg on Debian 9. liblqr-1-0-dbg is converts plain array images into multi-size representation (debug package)

Introduction

In this tutorial we learn how to install liblqr-1-0-dbg on Debian 9.

What is liblqr-1-0-dbg

liblqr-1-0-dbg is:

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 http://www.faculty.idc.ac.il/arik/imret.pdf
