基于塊編碼視頻的無參考質量評估
A No-reference Quality Assessment Method for Block-Coding Video
-
摘要: 該文提出了一種適用于基于塊編碼視頻的無參考質量評估方法。首先結合人類視覺的亮度掩蓋和對比度掩蓋特性提出了一個符合主觀視覺感知的方塊效應測度，然后根據(jù)濾波對方塊效應的影響，給出了一種適合于使用不同壓縮和處理算法的基于塊編碼重構視頻的質量評估方法。實驗表明該質量評估測度與主觀質量評估有較好的一致性。Abstract: A new no-reference quality assessment method for block-coding video is presented in this paper. Firstly, a new blocking artifact metric is presented based on Human Visual System(HVS) taking into account of the luminance masking and activity masking characteristics. Then, with consideration of the effect of filtering, a method is proposed for assessing the quality of the reconstructed videos compressed with different block-coding algorithms. Experimental results show that the proposed no-reference quality assessment method has good consistency with subjective quality assessment methods.
