摘要: 提出一种解决二维卷积中信息丢失的方法.理论研究表明二维非中心点评估的卷积整数是一些确定的中心点的卷积整数的线性组合.求解出一系列非中心点评估的卷积整数,以保证处理二维数据阵时不会发生信息丢失的情况.本文还讨论了二维非中心点卷积整数的对称性和整套卷积参数的重要性.

关键词: 数据丢失, 信息弥补, 非中心点卷积整数, 线性组合

Abstract: Amethod has been proposed for the remedy of the information loss at the marginal belts in 2D-convolution.Theoretical study shows that the 2D-convolution integers for noncentral point evaluation can be found just by using linear combination of those for the central points.New integers acquired ensure that the information loss would not happen while doing derivation with 2D-experimental data array.The related items concerning the symmetry of these integers and the importance of identifying all convolution parameters were also discussed.

Key words: Data truncation, Information remedy, Noncentral point convolution integers, Linear combination
