Transfer an image sequence into an optic flow field.

Flow fields are calculated for each pair (t,t+1) of the sequence independently. The motion vector for each pixel in image t is estimated by searching the most similar looking pixel in image t+1. The similarity measure is Pearson Product-Moment Correlation Coefficient of all pixels in a local vicinity. The local vicinity is defined by a block and is calculated using an IntegralImage. Both the size of the block and the search radius are parameters of the method.
