/*
	The main function is an example of video dehazing 
	The core algorithm is in "dehazing.cpp," "guidedfilter.cpp," and "transmission.cpp". 
	You may modify the code to improve the results.

	The detailed description of the algorithm is presented
	in "http://mcl.korea.ac.kr/projects/dehazing". See also
