Average Intensity of Pixels in Image Solution

Follow our step by step solution on how to calculate Average Intensity of Pixels in Image?

FIRST Step Consider the formula

m i = \sum (x, 0, (L gray - 1), (r i \cdot p[r i]))

Next Step Substitute values of Variables

∴

m i = \sum (x, 0, (118 - 1), (15W/m² \cdot 0.59))

Next Step Prepare to Evaluate

∴

m i = \sum (x, 0, (118 - 1), (15 \cdot 0.59))

LAST Step Evaluate

∴

m i = 1044.3W/m²
