Extension of Bilateral Filter and Its Application to Next-Generation Cameras

在整个研究过程中，我们开发了双边滤波器对多模态图像和高速计算算法的扩展，并设计了其在计算机上实现的智能图像处理中的应用。计算摄影是一项新兴技术，对下一代相机的发展具有核心作用。对于双边滤波器，我们开发了移位加权滤波器、系数反转滤波器、分段滤波器和各向异性滤波器。我们已经将它们应用于非真实感渲染技术，如点画，线条画，彩色玻璃图像和多值半色调。

Throughout this research, we have developed an extension of the bilateral filter to multimodal images and high-speed computational algorithms and have devised its application to intelligent image processing with its implementation to computers. The bilateral filter has taken attention as a fundamental algorithm of the computational photography which is an emerging technology having central role for developing next-generation cameras. For the bilateral filter(BF), we have developed a shift-weighted BF, coefficient-inverted BF, segment BF and anisotropic BF. We have applied them to non-photorealistic rendering techniques such as stippling, line drawings, stained glass images and multi-valued half-toning.
