Linear regression model used to estimate the optimum background threshold. The preset linear regression model was used to determine the optimum threshold, then the reverse threshold was determined and the >95% correlation between the optimum threshold value and the mean (standard deviation) of the image was calculated. The optimum threshold value of each image was estimated using this regression model
