多通道编码摄影中的数字化白光信息处理

本文提出了用于多通道编码摄影的数字化白光信息处理的三种方法。融合零级谱解码方法利用了信噪比较高的零级谱亮度信息,使解码图像质量大为改善;“原子”解码算法只通过一次傅氏变换即完成解码;而整数傅氏变换避免了变换最耗时的浮点运算。这些方法的综合运用使数字白光信息处理在多通道编码摄影中得以技术实用化,不仅显著改善了解码图像质量,而且大幅度提高处理速度达６０倍以上。

Digital White-light Information Processing for Encoding Multiple Channel Photography

Three techniques of digital white-light information processing are presented. The fusing zero-order spectrum algorithm applies the lightness information from zero-order spectrum to improve the quality of decoding image remarkably. The “atomic” algorithm performs decoding process using Fourier transformation only once and the integral Fourier transformation works without floating operation. While improving image quality greatly and processing speed more than 60 times, the techniques make the digital white-light information process practical in multiple channel photography.
