Generative adversarial network (GAN)-guided visual quality evaluation means scoring GAN-propagated portraits to quantify the degree of visual distortions. In general, there are very few image- and character-evaluation algorithms generated by GAN, and the algorithm's athletic ability is not capable. In this article, we proposed a novel image ranking algorithm based on the nearest neighbor algorithm. It can obtain automatic and extrinsic evaluation of GAN procreate images using an efficient evaluation technique. First, with the support of the artificial neural network, the boundaries of the variety images are extracted to form a homogeneous portrait candidate pool, based on which the comparison of product copies is restricted. Subsequently, with the support of the -nearest neighbors algorithm, from the unified similarity candidate pool, we extract the most similar concept of K-Emperor to the generated portrait and calculate the portrait quality score accordingly. Finally, the property of generative similarity that produced by the GAN models are trained on a variety of classical datasets. Comprehensive experimental results have shown that our algorithm substantially improves the efficiency and accuracy of the natural evaluation of pictures generated by GAN. The calculated metric is only 1/9-1/28 compared to the other methods. Meanwhile, the objective evaluation of the GAN and human consistency has increased by more than 80% in line with human visual perception.
生成对抗网络(GAN)引导的视觉质量评估是指对GAN生成的人像进行评分,以量化视觉失真程度。一般来说,由GAN生成的图像和人物评估算法非常少,且该算法的性能不佳。在本文中,我们提出了一种基于最近邻算法的新型图像排序算法。它可以使用高效的评估技术对GAN生成的图像进行自动和客观的评估。首先,在人工神经网络的支持下,提取各种图像的边界以形成一个同质的人像候选池,在此基础上限制产品副本的比较。随后,在K近邻算法的支持下,从统一的相似性候选池中,提取与生成的人像最相似的K个概念,并据此计算人像质量得分。最后,在各种经典数据集上对GAN模型产生的生成相似性属性进行训练。综合实验结果表明,我们的算法显著提高了对GAN生成图片进行自然评估的效率和准确性。与其他方法相比,计算出的指标仅为其1/9 - 1/28。同时,GAN的客观评估与人类的一致性符合人类视觉感知,提高了80%以上。
