摘要
我们提出了一种利用分四元数进行白平衡的感知色度适应变换(CAT)。本研究的新颖之处在于强调了该模型中出现的代数结构与分四元数的某个子代数之间的联系。我们提出了一种通过适当使用分裂四元数乘法实现的 CAT,从而展示了这种方法在彩色图像处理应用中的潜力。此外,我们还提供了与广泛使用的最先进的 von Kries CAT 的定量比较。
Split-Quaternions for Perceptual White Balance: A quantum information-based chromatic adaptation transform [Hypercomplex Signal and Image Processing]
We propose a perceptual chromatic adaptation transform (CAT) for white balance that makes use of split-quaternions. The novelty of the present work, which is motivated by a recently developed quantumlike model of color perception, consists of stressing the link between the algebraic structures appearing in this model and a certain subalgebra of the split-quaternions. We show the potential of this approach for color image processing applications by proposing a CAT implemented via an appropriate use of the split-quaternion multiplication. Moreover, quantitative comparisons with the widely used state-of-the art von Kries CAT are provided.
