摘要:

针对图像混合失真类型判定难的问题,在深度学习多标签分类思想的基础上,提出了一种基于多尺度多分类器卷积神经网络(CNN)的混合失真类型判定方法。首先,从图像中截取得到含有高频信息的图像块,将该图像块输入到不同感受野的卷积层中以提取图像的浅层特征图;其次,将浅层特征图输入到各子分类器结构中以进行深层次的特征提取和融合,将融合的特征通过Sigmoid分类器得到判定结果;最后,将各子分类器的判定结果进行融合得到图像的混合失真类型。实验结果表明,在自然场景混合失真数据库(NSMDID)上,所提方法对图像中存在的混合失真类型的平均判定准确率可以达到91.4%,且对大部分类型的判定准确率都在96.8%以上,可见所提方法能够对混合失真图像中的失真类型进行有效的判定。

Abstract:

It is difficult to judge the image multiply distortion type. In order to solve the problem, based on the idea of deep learning multi-label classification, a new multiply distortion type judgement method based on multi-scale and multi-classifier Convolutional Neural Network (CNN) was proposed. Firstly, the image block containing high-frequency information was obtained from the image, and the image block was input into the convolution layers of different receptive fields to extract the shallow feature maps of the image. Then, the shallow feature maps were input into the structure of each sub-classifier for deep feature extraction and fusion, and the fused features were judged by the Sigmoid classifier. Finally, the judgment results of different sub-classifiers were fused to obtain the multiply distortion type of image. Experimental results show that, on the Natural Scene Mixed Disordered Images Database (NSMDID), the average judgment accuracy of the proposed method can reach 91.4% for different types of multiply distortion types in the images, and most of them are above 96.8%, illustrating that the proposed method can effectively judge the types of distortion in multiply distortion images.
