This article needs a lot of clearing up. Although the formulas are correct its notation is unclear for people who don't know the Viola/Jones paper. What is A, B, C, D? A sum, area or a point? What is the function A(x)? What is i(x,y)? What is the one argumented function I(X) opposed to I(x, y)? All these are essential points missing. --85.177.99.146 (talk) 13:41, 26 January 2013 (UTC)[reply]

The formula seems to be incorrect, the sum I(C)+I(A)-I(B)-I(D) calculates rectangle NOT including A, that is x0<(!)<=x1 and y0<=y<(!)y1.
