【摘要】 本文研究彩色图象的合成问题，阐述了亮度计算的统计直方图原理，提出了彩色图象合成中亮度匹配的直方图规定化方法、给出了它的离散形式，以便程序实现，并对处理中的具体问题进行了讨论，使用证明该方法在彩色图象合成中能获得较好的亮度匹配效果。更多还原

【Abstract】 The composition problem of chromatic images is studied in this paper. The algorithm of lightness and hue calculation and the theory of statistical histogram are analyzed. A method of histogram specification is presented to match the lightness of images. The discrete representation is given for programming implementation. Some concrete problems in processing are discussed. The application of this method has brought about some better results in lightness matching in composition of chromatic images.更多还原
