摘　　要：为了解决显示屏亮度不统一所引起的多媒体网页图像色彩退化的问题,设计一种基于RGB模式的图像色形增强模型。根据RGB模式的要求,对视觉图像从照度和反射两个分量的角度进行光滑化处理,在此基础上,利用RGB格式的增强系数,建立视觉图像的色彩增强函数。通过增强多媒体网页中视觉图像的整体亮度、调整图像局部对比度,恢复图像色彩的方式,增强视觉图像的色彩。在Windows XP系统内进行图像色形增强效果的检测,结果显示,基于RGB模式的色彩增强模型能够切实增强图像的亮度、信息爛、饱和度。说明该模型具备有效性,较传统的直方图均衡模型的图像色彩增强效果好,符合实际推广应用标准。In order to solve the problem of color degradation of multimedia webpage images caused by different brightness of display screen,an image color enhancement model based on RGB mode is designed.According to the requirement of RGB mode,the visual image is smoothed from the perspective of illumination and reflection.On this basis,the color enhancement function of visual image is established by using the enhancement coefficient of RGB format.By enhancing the overall brightness of the visual image,adjusting the local contrast of the image,the color of the image is restored,and the color of the visual image can be enhanced.The results show that the color enhancement model based on RGB mode can effectively enhance the brightness,information entropy and saturation of the image.It shows that the model is effective and has better image color hancement effect than the traditional histogram equalization model,which meets the practical popularization and application standards.
