Frame Interpolation Algorithm Using Improved 3-D Recursive Search

摘要：

　　A low-complexity and high efficiency method for Motion-Compensated Frame Interpolation is developed in this paper.The 3-D recursive search technique is used together with bilateral motion estimation scheme to predict the block motion vector field without yielding the hole and overlapping problems.A stepwise multi-stage block-motion estimation scheme is designed to deal with the complex motion object in a block.To reduce the block artifact and keep the computational efficiency,a simplified median filter is developed to smooth the estimated motion vector field.Experimental results show that the proposed algorithm provides a better image quality than several broadly used methods both objectively and subjectively.The high computational efficiency makes this proposed algorithm a useful tool for real-time decoder of high-quality video sequences.
