一种基于模糊推理的交通监控图像客观评价方法
|
摘要
交通监控图像好坏是闭路电视监控系统的重要性能参数。在分析现有交通监控图像评价方法的基础上,提出一种操作简便的无参考评价方法,从基本属性、清晰度、抗干扰性能角度构建客观评价指标体系,并采用模糊推理算法对多个指标进行推理以获得反映图像好坏的中间量,进而建立中间量到图像客观评分的映射关系。试验结果表明,该方法有效且评分结果符合人眼主观感受。
The quality of traffic monitoring images is an important performance parameter of CCTV monitoring system.After the analysis of the existing method of evaluating traffic monitoring images,a simple and non-reference evaluation method is put forward,which builds an indicator system objective evaluation based on basic property,clarity,anti-interference performance.The intermediate values reflecting image quality are obtained by applying fuzzy inference algorithm to a number of indicators,which are used to establish the mapping relationship between the intermediate quantity and the objective scoring of images.The test results show that this method is effective and the score is in line with the subjective perception of human eyes.
