【摘要】 图像放大是图像处理的一个重要研究领域,目前已经提出了多种图像放大方法,但如何评价放大后图像质量,仍然是一个值得研究的课题。本文提出了一种基于熵的放大后图像质量的评价方法,并给出了仿真结果,并与其他几种客观评价方法进行了比较。结果表明,这种方法与主观评价方法得到的结论更为接近,是一种较理想的评价方法。更多还原

【Abstract】 Image zooming is an important research area in image processing. There are many methods of image zooming, while how to evaluate the quality of zoomed images remains unsolved. In this paper, a new method of zoomed images; evaluation, EEM (entropy evaluation method), is proposed. It has a good effect as the same as MOS (Mean Opinion Score). It is better than other objective methods such as MES , LVE, SFM.更多还原
