Histogram Equalization Transformation Solution

STEP 0: Pre-Calculation Summary

Formula Used

Transformation of Continuous intensities = (Number of Intensity Levels-1)*int(Probability Density Function*x,x,0,Continuous Intensity)
T_r = (L-1)*int(P_r*x,x,0,r)
This formula uses 1 Functions, 4 Variables

Functions Used

int - The definite integral can be used to calculate net signed area, which is the area above the x -axis minus the area below the x -axis., int(expr, arg, from, to)

Variables Used

Transformation of Continuous intensities - Transformation of Continuous intensities can be obtained once probability density function has been estimated from the input image.
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.
Probability Density Function - Probability Density Function is the density function of continuous random variable of an input image.
Continuous Intensity - Continuous Intensity is the continuous random variable of an input image.

STEP 1: Convert Input(s) to Base Unit

Number of Intensity Levels: 4 --> No Conversion Required
Probability Density Function: 0.2 --> No Conversion Required
Continuous Intensity: 64 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

T_r = (L-1)*int(P_r*x,x,0,r) --> (4-1)*int(0.2*x,x,0,64)

Evaluating ... ...
