摘要
数字影像构像质量的正确评价是一项很有意义但又有一定难度的研究课题。对现有数字影像的质量评价 方法进行了较全面的综述,侧重介绍了各自方法的基本原理、算法模型和性能特点。文章最后指出基于调制传递函 数(MTF)测定并结合人眼视觉系统(HVS)模型的影像质量评价方法有望成为解决影像质量评价难题的突破点。
It is a very meaningful and difficult research project to evaluate quality of digital images faithfully. The existing methods on image quality assessment are generally summarized, and their basic theories, algorithm models and characteristics are introduced particularly.At last, it is presented that image quality assessment method combined modulation transfer function (MTF) with human visual system (HVS) may be a new breakthrough to solve the image quality problem.
