We propose an artifact analysis in computational integral imaging and the image enhancement method based on the analysis using the smooth windowing technique. Blurring and lenslet artifacts, which are major problems in computational integral imaging, are defined and analyzed using a signal model. Applying a smooth and continuous window such as the triangular window to computational integral imaging reconstruction provides a dramatic improvement in terms of image quality. Experimental results are presented to show the validity of our method. To our best knowledge, this is the first trial to control a window function in computational integral imaging.
我们提出了一种在计算积分成像中的伪影分析以及基于使用平滑窗口技术的分析的图像增强方法。使用信号模型定义和分析了计算积分成像中的主要问题，即模糊和微透镜伪影。在计算积分成像重建中应用平滑连续的窗口，例如三角形窗口，可以显著提高图像质量。给出了实验结果以验证我们的方法的有效性。据我们所知，这是首次尝试在计算积分成像中控制窗口函数。
