摘要
利用计算机信息技术处理数码图像,对观赏海棠(Malussp.)主要观赏器官的颜色进行数字化描述,从而更准确科学地描述其形态。采用Photoshop CS3软件对试材图像进行处理,分别提取叶片、果实、花瓣及新梢的典型色域的CMYK模式参数,通过C、M、Y、K的百分比值确定其颜色。结果表明,用C、M、Y、K的百分比值表现观赏海棠叶片、果实、花瓣和新梢幼叶的色彩,可以反映品种间差异,从而为品种描述和新品种的选育指标提供新的数字化方法。
The computer information technology combined with digital images were used to describe ornamental crabapple's flower,fruit and leaf color,so as to describes the ornamental crabapple's characteristics more accurately and scientifically.We extracted pattern parameters of CMYK separately in the typical color region from leaves,fruits,flowers and new shoot's leaf using Photoshop CS3,then,determined the color percentage of C,M,Y,K.The results indicated that the ornamental crabapple's color could be represented by the percentage of C,M,Y,K,and could be observed the differences between existing varieties and new varieties easily.Digital technology was used to describe ornamental crabapple's leaf,fruit,flower and new shoot color,so as to provides a basis for breeding new varieties,through this method we can restore the plant's color scientifically and accurately,and reflect the differences between varieties easily.
