What is Nth Moment of a Discrete Random Variable in Digital Image Processing ?

The nth moment of a discrete random variable, in the context of digital image processing, characterizes the statistical properties of the intensity distribution in an image.
Statistical Properties: Different moments capture different aspects of the distribution, such as:
Mean (n = 1): Average intensity level (overall brightness).
Variance (n = 2): Spread of intensity values around the mean (high variance indicates high contrast).
Skewness (n = 3): Asymmetry of the distribution (positive skew suggests more bright pixels).
Kurtosis (n = 4): "Peakedness" of the distribution compared to a normal distribution.

What are the Applications of Nth Moments ?

Image Segmentation: Identifying regions with similar intensity characteristics, which can be helpful in segmenting objects from the background.
Feature Extraction: Extracting quantitative features from images based on moments, such as texture analysis or shape recognition.
Image Quality Assessment: Analyzing the distribution of intensity levels to assess factors like contrast or noise levels in an image.
