Mean Value of Pixels in Neighborhood Solution

STEP 0: Pre-Calculation Summary

Formula Used

Subimage Pixel Mean Intensity Level = sum(x,0,Number of Intensity Levels-1,Pixel Intensity Level*Probability of Occurrence of Rith in Subimage)
m_Sxy = sum(x,0,L-1,r_i*p_{Sxy_ri})
This formula uses 1 Functions, 4 Variables

Functions Used

sum - Summation or sigma (∑) notation is a method used to write out a long sum in a concise way., sum(i, from, to, expr)

Variables Used

Subimage Pixel Mean Intensity Level - Subimage Pixel Mean Intensity Level represents the mean intensity level of pixels in the subimage S_xy.
Number of Intensity Levels - Number of Intensity Levels is the total number of distinct intensity values an image can represent, determined by its bit depth.
Pixel Intensity Level - (Measured in Watt per Square Meter) - Pixel Intensity Level refer to the range of possible intensity values that can be assigned to pixels in an image. This concept is particularly relevant in grayscale images.
Probability of Occurrence of Rith in Subimage - Probability of Occurrence of Rith in Subimage represents the probability of occurrence of the intensity level r_i within the subimage S_xy.

STEP 1: Convert Input(s) to Base Unit

Number of Intensity Levels: 4 --> No Conversion Required
Pixel Intensity Level: 15 Watt per Square Meter --> 15 Watt per Square Meter No Conversion Required
Probability of Occurrence of Rith in Subimage: 0.25 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

m_Sxy = sum(x,0,L-1,r_i*p_{Sxy_ri}) --> sum(x,0,4-1,15*0.25)

Evaluating ... ...

m_Sxy = 15

STEP 3: Convert Result to Output's Unit

15 --> No Conversion Required

FINAL ANSWER

15 <-- Subimage Pixel Mean Intensity Level

(Calculation completed in 00.004 seconds)

LaTeX Go

Subimage Pixel Mean Intensity Level = sum(x,0,Number of Intensity Levels-1,Pixel Intensity Level*Probability of Occurrence of Rith in Subimage)
m_Sxy = sum(x,0,L-1,r_i*p_{Sxy_ri})

What is the Mean Value of Pixels in Neighborhood?

The global mean and variance are computed over an entire image and are useful for gross adjustments in overall intensity and contrast. A more powerful use of these parameters is in local enhancement, where the local mean and variance are used as the basis for making changes that depend on image characteristics in a neighborhood about each pixel in an image.
