Abstract: To achieve medium level visual region texture substitution in multi-regions contour curves, a multi-region image reconstruction algorithm was proposed. Firstly, the segmented region and index list of original image were extracted. Secondly, the polynomial coefficients representing region structure feature were got by piecewise iterative curve fitting and the smallest region texture sample was selected. Finally, the reconstructed region contour and synthesized region texture were used to achieve regional restoration. The proposed algorithm can be done successfully for images with massive textures. The experimental results show that it can reduce the amount of data required by image reconstruction and be applied to reconstruct the still background of image and video.
