CASE 2: Homography makes it regular, frame needs to be reconstructed

CASE 2.1: Homography makes it awful, a new frame needs to be selected

CASE 3: Homography makes it awful, a new frame needs to be selected

Usage:
< Program_name > < Settings_file > [ Range_min = 0 ] [ Range_max = num_frames ]

Example 1: Run VideoStabilization in the Experiment_1 processing the whole video.
-> VideoStabilization Experiment_1.xml
Example 2: Run VideoStabilization in the Experiment_1 processing from the 150 frame until the last one.
-> VideoStabilization Experiment_1.xml 150
Example 2: Run VideoStabilization in the Experiment_1 processing from the 150 frame until the frame 490.
-> VideoStabilization Experiment_1.xml 150 490

The program can exit with following codes:
-1 - Wrong number of input parameters.
-2 - Experiment id does not exist.
-3 - Can not open the accelerated video.
-4 - Can not create file to save the output video.
-5 - Can not open the video original video.
-6 - Can not open the CSV file with the selected frame numbers of the accelerated video.
-7 - Can not create directory to save the output data.
-8 - Can not create log text file.
-9 - Range limits is not well defined.
-10 - Can not open the CSV file with the semantic costs of the original video.
-11 - transition from frame_src to frame_dst larger than number of transitions describle int the file the semantic costs

Parameters

argc	- number of parameters in argv.
argv	- < Settings_file > [ Range_min = 0 ] [ Range_max = num_frames ]
