The REVIEW database
*********************************************************


The database includes:
======================

1) The original colour photos for the four sets.
------------------------------------------------

Four folders of image sets
	CLRIS: Central light Image Set
	HRIs: High Resolution Image Set
	KPIS: Kick Point Image Set
	VDIS: Vessel Desease Image Set

2) The edge points of three observers for the four sets.
--------------------------------------------------------
	Observer Marking for CLRIS
	Observer Marking for HRIS
	Observer Marking for KPIS
	Observer Marking for VDIS

Each of these files consists of 15 columns: Series number, image number, segment number and four columns for three observers.
For each observes, there are four columns for two points on each edges (x1,y1,x2, and y2).

From these two points (x1,x2) and (x2,y2), you might calculate: centre point, local width at that point and local direction at that point.
	The centre point equals (x1+x2)/2 and (y1+y2)/2.
	The width equals SQRT((x1-x2)^2+(y1-y2)^2).
	The direction equals ATAN2(y2-y1,-(x2-x1)).
