Abstract
Image quality detection technology can automatically detect the image abnormality in order to replace manual inspection methods for the monitoring system.It can accurately analyze abnormalities of the video,and alarm the system in order to ensure normal running of the expanding network video surveillance system.Noise detection technology based on the spatial domain uses the image information of the field characteristics,profiles and orientation distributions of various kinds of abnormal noise in spatial domain,and takes advantage of OpenCV-based image processing technology achieving detection of noise points,snowflakes and stripes.The noise detection algorithm in spatial domain proposed,is consistent with human visual perception and can be used to monitor video for real-time detection.
