摘要
由于高清数码影像获取过程中经常受到多种因素的影响,从而导致观测到的影像质量降低,为后续的数据分析带来诸多困难。针对这种情况,首先对传统的客观影像质量评价方法进行分析;然后提出一种基于调制传递函数的无参考型影像质量评价方法;最后通过对比试验证明该方法的可行性与可靠性。实验结果表明:针对高清数码影像,基于调制传递函数的评价方法与人眼主观评价结果一致,并较传统的像质评价方法更稳定。
Digital image acquisition is often influenced by many factors, which leads to the decrease of the quality of the image and brings many difficulties to the subsequent data analysis. Thus, the theory and method of the evaluation and recovery of digital image are studied. First of all, the traditional objective evaluation method of image quality is intro- duced. Then, a no-reference image quality assessment method based on the modulation transfer function is described. Finally, comparison tests show that the method is feasible the modulation transfer function is consistent with the traditional image quality evaluation methods. and reliable. The results show that the evaluation method based on subjective evaluation of human eyes, and is more stable than the
