Noise Estimation by Utilizing Mean Deviation of Smooth Region in Noisy Image

Abstract: Abstract-In many practical cases of image processing, only a noisy image is available. Many image denoising methods usually require the exact value of the noise distribution as an essential filter parameter. However, to estimate the noise solely from the information of the noisy image is a difficult task. A simple but accurate noise estimator would significantly benefit many image denoising methods. In this paper, we present a method to estimate additive noise by utilizing the mean deviation of a smooth region… Show more

“…Noise information is collected by estimating the noise properties from a specified smooth region. One such method is the mean absolute deviation technique (MADT) [13]. Assuming the noisy 1-D signal is represented by f with n samples and its mean by µ f , then the mean deviation (MD) is presented as…”

“…The median absolute differences (MAD) may be used instead of the average of absolute differences so that the effect of the noises is reduced on the dissimilarity measure. Although, salt and pepper noise has a considerable effect on the Manhattan measure, it has minimal effect on MAD [36]. MAD is mathematically defined as finding out the differences between the absolute intensities of the corresponding pixels of two images and then taking the median of the orderly data as the dissimilarity measure.…”
