1. A computer-implemented method, comprising: assessing a likelihood of having a video on film (VOF) object edge along one of n pre-defined directions, the assessing comprising: generating n sets of reference quantities, wherein each reference quantity is associated with a corresponding one of n pre-defined directions; and generating two additional reference quantities R[1] and R[2] by applying classical logic to the n sets of reference quantities; determining a weighting factor k by analyzing R[1] and R[2] using fuzzy logic interference rules; and performing de-interlacing at a current processing pixel based at least in part on the weighting factor k.
