Detailed Description

This is an alignment strategy for activeShapeModels (ASM), that works on a gradient channel and a skin probability channel, to trace skin colored objects.

In addition to the feature selection in the class gradientASM, feature points have to be skin colored in the inside region and non-skin colored in the outside region. Points are valid, when they only contain skin points on the inside of the shape (along the normal, within a distance <= 'parameterssearchExtent'). If no such points are found, search is continued further inside the shape (see parameters::shrinkExtent). When too many points are completely surrounded by skin, search for a skin border is continued further outside the shape (see parameters::enlargeExtent).

Important note: Due to the inside/outside nature, the points of the shape must be given in clockwise order!
