摘要/Abstract

摘要： 针对块效应下无参考图像质量评价，提出了双向过滤法（bidirectional filtration），通过分辨图像真边界与假边界进行块效应下图像评价。该方法从两个不同的场域对图像边界进行逐层过滤，达到对真边界的有效定位，最后通过评价模型得出评价值。实验测试结果得出的数据与SSIM 模型相比有了一定的改进。

Abstract: To evaluate the image quality without reference under blocking effect，the author proposed a bidirectional filtration （BIF） method，which aims at providing a new idea for boundary selection，and resolved the image evaluation under blocking effect more effectively by distinguishing the true and false boundary of the image. The method filtered the image boundary layer by layer from two different fields to locate the true boundary effectively. Finally，the evaluation values were obtained through the evaluation model. Compared with SSIM model，the data obtained from the experimental results were improved to a certain extent. It is concluded that this method is more accurate in evaluating the no-reference image under blocking effect.

Key words: bidirectional filtration, image quality assessment, image boundary
