自然图像质量评价方法综述

5G时代的到来使得图像处理技术也得到了迅猛发展,自然图像质量评价方法成为图像处理领域的重要研究热点。在自然图像获取、图像压缩、存储等处理时,图像质量不可避免的产生各种类型的失真,从而自然图像质量评价方法的应用越来越广泛。首先阐述自然图像的失真类型和公开标准图像数据库的相关知识,然后分别从主观评价和客观评价两种方法分析自然图像质量评价,最后对未来自然图像质量评价方法的发展趋势进行了总结和展望。

Survey of Natural Images-Quality Assessment Method

The advent of the 5G era has led to rapid development of image processing technology, natural image quality assessment(NIQA) method becomes to an important research hotspot in the field of image processing. When acquiring natural images, image compression, storage, etc., the image quality inevitably produces various types of distortion. Therefore, the application of IQA is more and more extensive.First, Explain the types of distortion of natural images and relevant knowledge of open standard image database, Next, according to analyze the natural image quality from two methods: subjective evaluation and objective evaluation, Finally, the development trends of future NIQA are summarized and prospected.
