A novel frame-rate up conversion using pseudo-true motion vector

In this paper, a method of estimating true motion vectors to reduce image quality deterioration such as block artifact is proposed. Three consecutive original input images are used to calculate the motion vectors. Among consecutive input images, the first and third frames are used to conduct interpolation and the block unit PSNR of the created interpolated frame and the second frame which is an original image is calculated to estimate a true motion vector. Then, the estimated true motion vector is applied to frame interpolation.
