The motivation behind writing this code is to make this algorithm compatible with different image formats. Moreover, OpenCV is one of the most widely used computer vision library, which makes this algorithm more flexible to use.
In addition to this, Robot vision platform rarely uses raw image formats(.ppm, .pgm etc), most of the time compressed image formats (say .jpg) are used. Hence, this algorithm can now be easily integrated with commonly used robot platform ROS(Robot Operating System).
To run this version of Software you must have few dependencies installed
a. OpenCV
b. cmake
Compilation Instructions:
a. cd GraphSegmentation (folder_ containing_GraphSegmentation_source)
b. mkdir build
c. cmake ..
d. make
Your binary will be in build/apps. Example image has been provided with this code in img folder to test quickly.
Execution command a) ./graph_segmentation ../../img/339.jpg
