The "Block Matching" algorithm and some related sw needs that moving
object dimensions doesn't changes along the scene crossing. This is usually
caused by the perspective effect. For this reason we have implemented a
trasformation in a software in order to reduce perspective distorsion drawbacks.
The transformation output is followed by a bilinear interpolation of grey
levels in order to smooth tone gaps.
