Abstract: The primary objective of this study is to enhance the precision of fog and mist noise reduction in photographsby introducing a novel Kalman filter and comparing its performance to that of an Adaptive filter. Materialsand Methods: For this investigation, the research dataset was sourced from the Kaggle database system. Usingtwenty iteration samples (ten for Group 1 and ten for Group 2), involving a total of 1240 samples, the efficacyof fog and mist noise elimination with improved accuracy was assessed. This evaluation was conductedemploying a G-power of 0.8, a 95% confidence interval, and alpha and beta values of 0.05 and 0.2,respectively. The determination of the sample size was based on the outcomes of these calculations. The novelKalman filter and the Adaptive filter, both utilizing the same number of data samples (N=10), were employedfor fog and mist noise removal from images. Notably, the Kalman filter exhibited a higher accuracy rate.Results: The novel Kalman filter showcased a success rate of 96.34%, outperforming the Adaptive filter'ssuccess rate of 93.78%. This difference in performance is statistically significant. The study's significancethreshold was set at p=.001 (p<0.05), confirming the significance of the hypothesis. This analysis was carriedout through an independent sample T-test. Conclusion: In conclusion, the proposed Kalman filter model,achieving an accuracy rate of 96.34%, demonstrates superior performance compared to the Adaptive filter,which yielded an accuracy rate of 93.78%. This comparison underscores the efficacy of the Kalman filter inthe context of image noise removal.
