Updates

Version 1.0.2: new util classes in all the packages.

Overview

DLib is a collection of C++ classes to solve common tasks in C++ programs, as well as to offer additional functionality to use OpenCV data and to solve computer vision problems.

I have found myself using these functions very often, so I hope they may be useful to other researchers and developers too.

DLib (DUtils, DUtilsCV, DVision) is published under a LGPL license.

Documentation

DLib is divided into 3 libraries for different purposes:

• DUtils (documentation): utilities for several common C++ program requirements. It includes these classes:

  • BinaryFile: reads/writes binary files
  • LineFile: reads/writes text files by lines
  • ConfigFile: reads/writes text files with the format key = value
  • FileFunctions: mkdir, rmdir, dir... functionality
  • Math: math functions
  • Random: pseudo-random number functions
  • STL: functions for STL containers
  • StringFunctions: functions to manipulae strings
  • Timestamp: operates with timestamps
  • TimeManager: manages collections of timestamps
  • Profiler: measures execution time of portions of code
  • DebugFunctions: functions to measure memory consumption

• DUtilsCV (documentation): utility functions for OpenCV data types. Classes included:

  • Drawing: functions to draw keypoints, data, axes...
  • GUI: shows images in windows and allows some user input
  • IO: I/O functions for storage and printing
  • Mat: functions to remove rows from matrices
  • Transformations: functions to deal with spatial transformations
  • Types: functions to convert between OpenCV data types

• DVision (documentation): functions to solve computer vision tasks. Classes included:

  • BRIEF: implementation of the BRIEF descriptor ([1]), with the modification described in [2]
  • FSolver: implementation of the RANSAC + 8-point algorithm to compute fundamental matrices between images
  • HSolver: implementation of the RANSAC + DLT algorithm to compute homographies between images
  • ImageFunctions: functions to get patches from images
  • SurfSet: manages SURF keypoints (keeping the laplacian sign) and descriptors
  • BundleCamera: reads/writes camera files created by the Bundle software
  • PMVSCamera, PatchFile, PLYFile: read/write data created by the PMVS software
  • PixelPointFile, Matches: read/write multi-purpose pixel and 3D data files
