591	Issue of SAO edgeIdx derivation	chihming.fu	bbross	"The Sign(x) function in the text is as follows,
if (x>=0), Sign(x)= 1,
otherwise if (x<0), Sign(x)= -1

However, the Sign(x) function for edgeIdx should be
if (x>0), Sign(x)= 1,
otherwise if (x==0), Sign(x)= 0
otherwise if (x<0), Sign(x)= -1

Therefore, we should define a new Sign1(x) function for edgeIdx,
  
edgeIdx = 2 + sum_k( Sign1( recPicture[ xC + i, yC + j ] – 
	recPicture[ xC + i + hPos[ k ], yC + j + vPos[ k ] ] ) ) with k = 0..1	(8-350)

where Sign1(x) function is as follows,
if (x>0), Sign1(x)= 0,
otherwise if (x==0), Sign1(x)=  0
otherwise if (x<0 ), Sign1(x)= -1
