摘要
图像增强是数字图像处理技术中的预处理过程,能够有效地改善图像的整体或局部特征.图像增强处理技术不仅能够突出数字图像的感官效果,而且能够为后期数字图像处理奠定坚实的基础.本文主要研究基于空域和频域的图像增强处理技术,为了实现对数字图像的增强处理,采用空域和频域相结合的方法对图像进行了增强处理,可以使图像的细部特征更加明显.
Image enhancement is the preprocessing of digital image processing technology,which can effectively improve the overall or local characteristics of the image. Image enhancement technology can not only highlight the sensory effects of digital images,but also lay a solid foundation for the later digital image processing.Image enhancement processing technology based on spatial and frequency domain is studied in this paper,in order to realize the enhancement processing of digital image,the methods of combination of spatial and frequency domain is adopted,which can make the image detail characteristic more obvious.
