中文摘要：

针对海洋文化印刷品中彩色海景图像存在视觉质量不佳的问题,结合RGB色彩模式和印刷品中常用的CMYK色彩模式的色域范围存在差异的特点,提出一种改进算法。结合分类和贪心选择的思想,对输入的彩色海景图像进行处理,实验结果表明,算法在对印刷品中海景图像进行增强的同时,有效地保护图像的色调信息,实现印刷品中海景图像视觉效果的优化。

英文摘要：

In view of the poor visual quality of color sea view images in marine culture prints, according to the differences in color gamut range between RGB color patterns and commonly used CMYK color patterns in printed matter, an improved algorithm is proposed. The algorithm combines the idea of classification and greedy selection, processing the input color sea view image. The experimental results show that the algorithm can effectively improve the hue information of the image while enhancing the sea view image in the printed matter, and realize the optimization of the visual effect of the sea view image in the printed matter.
