【摘要】 为了对视频编码质量进行客观评价,利用模糊综合评判的思想给出了一种客观视频质量评价模型。该模型可同时权衡视频压缩序列的图像清晰度、流畅性、运动抖动性等重要特征,并对其他评价模型和指标具有良好的兼容性。仿真实验结果表明,该模型能够对视频编码序列的多个特征进行较好的综合评价。相比以往评价模型具有实现简洁和可靠度高的优点。更多还原

【Abstract】 Since no well-established methods for objective quality evaluation are available,in this paper,a new efficient and reliable objective video evaluation model is proposed based on fuzzy synthetic judgment.Fuzzy control is combined with the objective evaluation.First,the essential idea of the model is described systemically.Then the fuzzy membership functions of all factors affecting the video quality are determined.And the fact weights are also estimated by proximate approach algorithm.This model highlights a comprehensive evaluation by taking into account various properties of the compressed video including video quality,fluency and motion speed,and has exlellent compatibility with other evaluation model or standard.Simulation results demonstrate that the proposed evaluation model outperform some other approaches and achieve more reliability.更多还原
