Intelligent Correction Method for Illumination Component of Video Surveillance Image in Multi-Scale Domain
An intelligent correction method for illumination components of video surveillance images multi-scale do-main is proposed to address issues such as insufficient clarity and uneven lighting in video surveillance images.Background difference method and difference graph binarization method is applied to preprocess video surveillance images to reduce noise interference and multi-scale detail features of images is strengthened by fusing TH transform and BH transform.The control factor is used to control the sharpening intensity,and the image artifacts are avoided while the details are highlighted.The image light component is adjusted adaptively,and the two-dimensional gam-ma function is used to calculate the average brightness of the image so as to prevent over-correction so that the in-telligent correction is achieved.The test results show that the image corrected by this method is clearer,the light component is uniform,the image is less distorted and the visual effect is better.
