Anaglyph Generator

This is an anaglyph generator that can use different anaglyph generation methods. Each method implements a simple interface. Each method has its own executable compiled for it.

Source Tree

bin/

The executables for each method and object files for c files directly inside "/".

images/

Some left and right eye anaglyph images you can use as examples.

methods/

Contains interface.h and one C file for each anaglyph method.

External Dependencies

Required:

• gcc
• OpenCV
• make

Optional:

• OpenMP - Used for multithreading. To turn this off, see the multithreading

  option in settings.mk

• lapack - Library that levmar uses for faster non-linear solvers. Read in

  levmar's README.txt about how to compile levmar with lapack.

Note that the video and image files that can be read and written are dependent on what libraries are available to OpenCV.

Mac Specifics

MacPorts can be used to install all of the above except for levmar and lapack. Installing OpenCV will also install FFMpeg support and OpenMP. For more details on Mac installation, read OpenCV's documentation:

Compiling

First you need to compile levmar, which is used as a non-linear least squares solver. Go into the levmar/ directory, which is inside the root of the repository. Next, run the "make" command inside this directory. This should compile levmar with some sane defaults. If needed, more details about compiling levmar can be found in levmar's "README.txt".

Levmar is only used for the cielab method. In the future, an option may be added to make levmar optional.

Next you need to create your settings file. Change directories back to the root of the repository. Copy "settings.mk.default" to "settings.mk". Open "settings.mk" and read through the options. You will need to change some of these before compiling. Read the comments in settings.mk for details.

To compile, run the "make" command inside the root of the repository. The executables generated, one for each method, will be placed in the bin/ directory.

Running

Run one of the executables in bin/<method_name> and pass in as arguments a left eye image and a right eye image as arguments. There are some sample anaglyph images in the images/ directory, with the files clearly labeled as corresponding left and right eye images.

For more help on usage, execute "bin/<method_name> --help".

Creating a Method

If you want to create your own anaglyph method, create a file named "methods/<method_name>.c". This file will automatically be compiled after following the steps in the "Compiling" section and the executable file will be put in bin/.

Look in methods/interface.h. This is the exact set of function prototypes that you need to have in your .c file. Read methods/interface.h for documentation on exactly what these functions do, and when they are called.
