摘要

提出了一种EDoF镜头图像的空间自适应图像恢复方法。讨论了实时应用的实际实现方法。对于基本图像的恢复，我们采用截断约束最小二乘(TCLS)滤波器，并计算局部方差自适应地选择观测图像和恢复图像的权重。实验结果表明，所提出的恢复算法能够有效地消除图像的退化，抑制噪声的放大。

Spatially Adaptive Image Restoration and its FIR Implementation

This paper presents a spatially adaptive image restoration for EDoF lens images. A practical implementation method is also discussed for real-time applications. For basic image restoration we adopt the truncated constrained least squares (TCLS) filter, and for adaptively selecting the weights of the observed and the restored images we compute local variance. Based on experimental results, we can claim that the proposed restoration algorithm can successfully remove the image degradation with suppressing noise amplification.
