示例1: Estimate
/*!
Estimates shift of current image relative to background image.
\param [in] current - current image.
\param [in] region - a region at the background where the algorithm start to search current image. Estimated shift is taken relative of the region.
\param [in] maxShift - a 2D-point which characterizes maximal possible shift of the region (along X and Y axes).
\param [in] hiddenAreaPenalty - a parameter used to restrict searching of the shift at the border of background image.
\param [in] regionAreaMin - a parameter used to set minimal area of region use for shift estimation. By default is equal to 25.
\return a result of shift estimation.
