论文摘要
提出了对最近邻居（NN）图像插值最合适的圆形功能的新评估研究。评估的圆形功能是在电气和电子工程师研究所（IEEE）定义的五个圆形规则中选择的，754-2008标准。全参考图像质量评估（IQA）指标都用于研究和评估圆形功能对NN插值图像质量的影响。对目标发生的事件实现的概念用于根据所使用的测试图像数量确定所发生的事件的百分比。推论统计分析用于从少数图像中推断出来，并在更大数量的图像上得出每个圆形函数的行为的结论。在正态分布和置信度等于95％的情况下，根据基于推论分析的实验，提供了每个评估的舍入函数的最大和最小值发生。
A novel evaluation study of the most appropriate round function for nearest-neighbor (NN) image interpolation is presented. Evaluated rounding functions are selected among the five rounding rules defined by the Institute of Electrical and Electronics Engineers (IEEE) 754-2008 standard. Both full- and no-reference image quality assessment (IQA) metrics are used to study and evaluate the influence of rounding functions on NN interpolation image quality. The concept of achieved occurrences over targeted occurrences is used to determine the percentage of achieved occurrences based on the number of test images used. Inferential statistical analysis is applied to deduce from a small number of images and draw a conclusion of the behavior of each rounding function on a bigger number of images. Under the normal distribution and at the level of confidence equals to 95%, the maximum and minimum achievable occurrences by each evaluated rounding function are both provided based on the inferential analysis-based experiments.
