dc.description.abstract | In this paper, we introduce an iterative second-order derivative-based intra-field deinter-lacing algorithm (ISDD). The proposed ISDD is composed of two steps: (1) preprocessing by a fast second-order derivative-based deinterlacing algorithm (FSDD), (2) iteratively refining the interpolated pixel by minimizing a mass second-order function. The function includes three components: the derivative difference, directional derivative, and isophote smoothing. The derivative difference is used to detect any intensity discontinuity in an image; the directional derivative is a supplement to the derivative difference to avoid oversmoothing; and isophote smoothing can reduce artifacts. The proposed ISDD can preserve image features and reduce the artifacts caused by conventional deinterlacing methods. Compared with existing deinterlacing algorithms, the proposed algorithm improves the peak signal-to-noise ratio while maintaining high efficiency. | - |
