|Abstract||In this paper a novel de-interlacing algorithm in spatial
domain is proposed based on an edge orientation optimizing strategy. Taking advantage of the resolution invariant
character of edge orientation we calculate the edge orientation in interlaced image by minimizing the cost function
sum of absolute difference(SAD). Under the assumption that
edge orientation in local area is stationary SAD stands for
the possibilities of each edge orientation. Interpolation in
the orientation with the least SAD will bring in the continuous value of missing pixels. In addition a threshold is set to
distinguish the texture area from edge or plain area which
makes the algorithm more robust.|
