摘要

针对边缘锐化问题，提出了一种改进的网格翘曲算法。网格变形的思想是对边缘的邻域进行变换，使边缘瞬变区域变细。这种方法不会放大噪声，也不会引入振铃伪影。改进的思想是分析梯度场在边缘点处的曲率并调整翘曲向量。

Image Sharpening by Grid Warping with Curvature Analysis

The paper proposes an improvement of the grid warping algorithm for solving the edge sharpening problem. The idea of the grid warping is to transform the neighborhood of the edges in order to make the edge transient area thinner. This approach does not amplify the noise and does not introduce ringing artifact. The idea of the improvement is to analyze the curvature of the gradient field at edge point and adjust warping vectors.
