fig6_8_EBMA.m: main function performing EBMA between two images using half_pel accuracy 
	Functions called: matching_half.m: half-pel EBMA between two images
			matching.m: integer-pel EBMA between two images
			plot_MV_function.m: plotting the motion field
	(function matching_half(..) can be replaced by matching(..)  to perform EBMA with integer pel accuracy)

Functions called: matching_half.m: half-pel EBMA between two images: used at last
			matching.m: integer-pel EBMA between two images: used in first three levels
			plot_MV_function.m: plotting the motion field

ch6_foreman.m: for generating eps files and calculating PSNRs used in Fig.6.8
example8_1_to_8_3.m: for generating entropy data in Examples 8.1-8.3
