接受色觉视网膜理论的第一个假设，即存在三个独立的亮度决定机制（一个用于长波，一个用于中波，一个用于短波），每个机制在不到一毫秒的曝光时间内起作用，每个都由自己的视网膜色素提供服务，视网膜理论的一个基本任务就是确定这些机制的性质。先前的参考文献提出了几种可行的算法。[Land， E. H. (1959) Proc. Natl.]学会科学。美国45,115 -129；Land， E. H.（1959）。学会科学。美国45,636-644；兰德，E. H.（1983）国家程序法。学会科学。USA 80, 5163-5169；Land， E. H. and McCann， J. J.（1971）。上午61,1-11；Land， E. H.（1986）《视觉》26,7-21。本文描述了一种相对简单的替代技术，用于计算retinex理论中的指示符，并报告了新技术的一般操作有效性，包括以前的算法所不具备的生成马赫波段的能力。
Accepting the first postulate of the retinex theory of color vision that there are three independent lightness-determining mechanisms (one for long waves, one for middle waves, and one for short waves), each operative with less than a millisecond exposure and each served by its own retinal pigment, a basic task of retinex theory becomes the determination of the nature of these mechanisms. Earlier references proposed several workable algorithms. [Land, E. H. (1959) Proc. Natl. Acad. Sci. USA 45, 115-129; Land, E. H. (1959) Proc. Natl. Acad. Sci. USA 45, 636-644; Land, E. H. (1983) Proc. Natl. Acad. Sci. USA 80, 5163-5169; Land, E. H. and McCann, J. J. (1971) J. Opt. Soc. Am. 61, 1-11; Land, E. H. (1986) Vision Res. 26, 7-21.] The present paper describes a relatively simple alternative technique for the computation of the designator in retinex theory and reports the general operational effectiveness of the new technique, including the competence, not possessed by earlier algorithms, for generating Mach bands.
