摘要
针对当前图像质量评价的研究现状,对各种评价方法进行了比较分析和归纳总结。利用U-Texas at Austin的LIVE图片库中的样本对几种常用的客观评价方法进行了测试,利用该数据库中得到广泛认可的主观评价分数,能够衡量客观评价指标与主观评价的符合程度,从而对这些评价指标的单调性、准确性和一致性进行了辨析和阐释,指出了其适用性和局限性。并利用VQEG推荐的方法对论断给出了实例印证。进而根据发展趋势和应用需求,对图像质量评价方法在应用中所必须面对的一些问题和解决途径提出了初步的见解。
Abstract
According to the current development trends in the image quality assessment,a series of assessment methodologies and their corresponding measures were comparatively analyzed in depth. Several conventional measures of performance indices are tested with samples from the image database of LIVE in U-Texas at Austin,based on which the monotonicity,veracity,and consistency of various index measures are discussed,expounded and commented by using the subjective scores in the database,so as to indicate their applicability and limitations. Thus the VQEG standard is employed to validate the correctness of the above results. Moreover,some important issues in engineering applications and possible solving approaches are proposed based on the current development trends and requirements of practical applications.
