双边滤波器是一种常用的边缘保持非线性滤波器。它通过限制外观不同的像素的贡献来防止对象边界上的平滑。尽管它的有用性，过滤器的复杂性，使它没有吸引力的高维数据和大的窗口大小。我们开发了一种新的技术来加速这个过滤器，使执行时间几乎是恒定的颜色维度和窗口大小的高光谱图像可以处理几乎一样快的灰度图像。
Bilateral filter is a popular edge-preserving nonlinear filter. It prevents smoothing across object boundaries by limiting the contribution of pixels dissimilar in appearance. Despite its usefulness, the complexity of the filter makes it unattractive for high dimensional data and large window size. We develop a novel technique to accelerate this filter so that the execution time is nearly constant with respect to the color dimensionality and the window size-a hyperspectral image can be processed almost as fast as a grayscale image.
