An Improved Block Stitching Method based on Bidimensional Empirical Mode Decomposition

The bidimensional empirical mode decomposition based on block partitioning(BBEMD) by using of radial basis function interpolation reduces the computational cost, but the blocking artefact is noticeable in the resulting mode. For alleviating the blocking artefact problem, we proposed a modified BBEMD. We calculate the enlargement size of each image block by the minimal symmetry resemblance variance of adjacent blocks, and integrate the decomposing results through a self-adaptive seamless splicing method. The experimental results demonstrate the effectiveness of the proposed method in alleviating the blocking artefact.
