利用远程彩色立体场景通常需要采集、传输和处理两种彩色图像。然而，与单眼图像或单色立体图像相比，传输和处理的信息量很大。应对这一挑战的现有方法侧重于压缩和优化。本文介绍了一种创新的互补方法来呈现彩色立体场景，专门用于人类感知。它依赖于一个假设，即由一个单色图像和一个彩色图像组成的立体图像对（MIX立体图像对）将被人类观察者感知为一个3-D彩色场景。利用颜色冗余的优势，单色对的这种表示允许所需带宽的急剧减少，甚至在使用任何压缩方法之前。在这里，我们描述了多达15个受试者的对照心理物理实验。这些实验使用不同的彩色和单色图像组合来测试颜色和深度感知。结果表明，即使在立体对中只呈现一幅彩色图像，受试者也能感知到三维彩色图像，没有深度感知退化，只有有限的颜色退化。这证实了假设并验证了新方法。
Utilizing remote color stereoscopic scenes typically requires the acquisition, transmission, and processing of two color images. However, the amount of information transmitted and processed is large, compared to either monocular images or monochrome stereo images. Existing approaches to this challenge focus on compression and optimization. This paper introduces an innovative complementary approach to the presentation of a color stereoscopic scene, specialized for human perception. It relies on the hypothesis that a stereo pair consisting of one monochromatic image and one color image (a MIX stereo pair) will be perceived by a human observer as a 3-D color scene. Taking advantage of color redundancy, this presentation of a monochromatic-color pair allows for a drastic reduction in the required bandwidth, even before any compression method is employed. Herein we describe controlled psychophysical experiments on up to 15 subjects. These experiments tested both color and depth perception using various combinations of color and monochromatic images. The results show that subjects perceived 3-D color images even when they were presented with only one color image in a stereoscopic pair, with no depth perception degradation and only limited color degradation. This confirms the hypothesis and validates the new approach.
