Answer 1

There is no equation of such, they are filters that are calculated by taking weighted sums of integrated areas of the images. There is a brief description of this in the OpenCV Cascade Classification documentation. The best thing to do is read the Viola and Jones paper:

Paul Viola and Michael J. Jones. Rapid Object Detection using a Boosted Cascade of Simple Features. IEEE CVPR, 2001.
