摘要

照明校正是一种用于消除来自环境的光和图像捕获过程中其他扭曲因素的影响的方法。提出了一种基于亮度映射的算法，该算法可用于去除低频强度变化，并在必要时提高低对比度区域的对比度。此外，该算法还可以保留与周围环境强度或颜色不同的中等大小物体的强度，否则这些物体往往会被洗掉。此外，还给出了如何将该方法用于灰度图像和彩色照片的实例。

A method of constructing phyllotaxically arranged modular models by partitioning the interior of a cylinder or a cone

Illumination correction is a method used for removing the influence of light coming from the environment and of other distorting factors in the image capturing process. An algorithm based on the luminance mapping is proposed that can be used to remove low frequency variations in the intensity, and to increase the contrast in low contrast areas when necessary. Moreover, the algorithm can be employed to preserve the intensity of medium-sized objects with different intensity or colour than their surroundings, which otherwise would tend to be washed out. Furthermore, examples are given showing how the method can be used for both greyscale images and colour photos.

期刊介绍： Machine GRAPHICS & VISION (MGV) is a refereed international journal, published quarterly, providing a scientific exchange forum and an authoritative source of information in the field of, in general, pictorial information exchange between computers and their environment, including applications of visual and graphical computer systems. The journal concentrates on theoretical and computational models underlying computer generated, analysed, or otherwise processed imagery, in particular: - image processing - scene analysis, modeling, and understanding - machine vision - pattern matching and pattern recognition - image synthesis, including three-dimensional imaging and solid modeling
