摘要
在立方体插值算法的基础上,提出了一种适合于实时应用的快速查找表结构。其中将涉及颜色空间转换和色域扩展的复杂算法使用硬件上的综合查找表完成,使用了计算速度较快的四面体插值算法。同传统的立方体插值算法相比,有效降低了硬件资源消耗并提高了运算速度。
A fast LUT architecture based on cube interpolation is described, which is suitable for real time systems. The highly nonlinear algorithm has been replaced by the integrated 3-D LUT. And a tetrahedron interpolation is introduced in this article. In contrast with the traditional cube interpolation algorithm, the new architecture brings a higher speed but lower hardware cost.
