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.application/pdf1948709 bytesapplication/pdfComputational methods; Decision making; Decision theory; Motion estimation; Vectors; Adaptive de-interlacing; Block size motion estimation; Interlaced block mode decision; Spatially-periodic patterns; Motion compensationconference paper10.1109/ICASSP.2005.14155542-s2.0-33646780594
