摘要:
提出一种新的基于支持向量回归的无参考屏幕内容图像质量评估算法. 首先,利用高斯差分函数计算边缘图,通过边缘图提取边缘特征; 其次,通过局部归一化获得亮度图,根据亮度图统计亮度特征; 最后,利用支持向量回归算法将质量感知特征映射为主观分数. 在两个数据集上的实验结果表明,所提算法的性能优于大部分现有算法.
Abstract:
The paper presents a new no reference quality assessment algorithm for screen content image based on support vector regression. Firstly,we calculate the edge map through the difference of Gaussians,which is further used to extract edge features. Secondly,we obtain the luminance map through the local normalization,which is further used to compute luminance features. Finally,we map the quality-aware features to subjective scores through the support vector regression algorithm. Experimental results on two data sets show that the performance of the proposed algorithm is better than those of the most of the existing algorithms.
