摘要
彩色图像中包含有丰富的细节信息,为了获得清晰的彩色图像,保护原有的彩色信息,消除亮度不够对彩色图像像质的影响,笔者在研究彩色图像增强原理的基础上,根据彩色图像的不同模型,对比了3种不同的彩色图像增强方法,并给出了实验结果。研究结果表明,应用增强彩色图像中的亮度信息的方法,既得到了清晰的彩色图像,又保护了原有的彩色信息,而且图像像质还强于Pho-toshop软件处理的效果。实验结果为彩色图像增强方法的选择提供了指导和参考依据。
Color image contains abundant detailed information. Based on different models of color image and the study on color image enhancement principle, three color image enhancement techniques are compared with each other to acquire a clear color image, protect the original color information and eliminate the effect of lack of brightness on image quality. The results show that by enhancing the image brightness, clear color image can be acquired, the original color information can be protected, and an image quality better than Photoshop can be obtained. The experimental results provide guidance and reference for the selection of color image enhancement technique.
