摘要

本文主要研究图像质量的主观和客观测试。采用不同的压缩算法(JPEG、KLT、Lura-wavelet)对图像进行处理，压缩比最高可达100。减压后对其进行了质量变化测试。首先采用主观图像质量测试(DSCQS)。然后应用基于人类视觉系统的度量进行客观质量测试。最后，对研究结果进行了讨论。

Image quality evaluation

This paper is devoted to subjective and objective tests of image quality. The images were processed using different compressing algorithms (JPEG, KLT, Lura-wavelet) with compression ratio up to 100. After decompression they were tested on the quality changes. At first the subjective image quality test (DSCQS) was used. Then the objective quality test using the metric based on the human visual system was applied. Finally, a discussion of the results is presented.
