Abstract
A four field variable block size motion compensated adaptive de-interlacing method is proposed to improve the accuracy of the motion vectors and lower the occlusions of motion compensated de-interlacing. The proposed de-interlacing method consists of variable block size motion estimation/compensation with four field SAD, interlaced block mode decision, and new block modes. The variable block size motion estimation/compensation improve the accuracy of the motion vectors, especially for spatially-periodic patterns. The new block modes and the interlaced block mode decision make block decisions more precisely, and special patterns that motion compensation cannot be compensated are correctly de-interlaced by these two methods. The subjective view shows the improvement of the accuracy of the motion vectors and the correctness of the mode decision. © 2005 IEEE.
