Cumulative Frequency for Each Brightness Value Solution

STEP 0: Pre-Calculation Summary

Formula Used

Cumulative Frequency for Each Brightness = 1/Total Number of Pixels*sum(x,0,Maximum Brightness Value,Frequency of Occurrence of Each Brightness Value)
K_i = 1/n*sum(x,0,N_max,f[BV_i])
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

Cumulative Frequency for Each Brightness - Cumulative Frequency for Each Brightness is a measure of how many pixels or data points have a brightness value less than or equal to a particular brightness level.
Total Number of Pixels - (Measured in Pixel) - Total Number of Pixels in an image or a digital representation of data is simply the count of individual picture elements that make up the image.
Maximum Brightness Value - (Measured in Watt per Square Meter) - Maximum Brightness Value refers to the highest intensity of light that a display can emit.
Frequency of Occurrence of Each Brightness Value - Frequency of Occurrence of Each Brightness Value indicates how many pixels share the same brightness level.

STEP 1: Convert Input(s) to Base Unit

Total Number of Pixels: 40 Pixel --> 40 Pixel No Conversion Required
Maximum Brightness Value: 17.48 Watt per Square Meter --> 17.48 Watt per Square Meter No Conversion Required
Frequency of Occurrence of Each Brightness Value: 80 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

K_i = 1/n*sum(x,0,N_max,f[BV_i]) --> 1/40*sum(x,0,17.48,80)

Evaluating ... ...

K_i = 36

STEP 3: Convert Result to Output's Unit

36 --> No Conversion Required

FINAL ANSWER

36 <-- Cumulative Frequency for Each Brightness
