Abstract:
A method for de-interlacing film source fields that might be mixed with video on film object edge, said method comprising the steps of:for a current processing pixel X, designating a direction D[j] (j as a element of {1, 2, . . . n}) through X as a likely direction to have a video on film object edge, said D[j] selected from n pre-defined directions (D[1] to D[n]) through X; and de-interlacing at X by assigning a pixel value to X according to a weighted sum of interpolation operation and merge operation, wherein said weighted sum is specified by a weighing factor k that is generated by applying fuzzy logic interference rules to an intrafield reference quantity R[1] and a inter-field reference quantity R[2], wherein said R[1] is adapted to quantify the maximum dissimilarity between a pair of intra-field pixels of X lying along D[j], and wherein said R[2] is adapted to quantify the minimum similarity between a pair of inter-field pixels of X lying along D[j].
