LAB #06
“STUDY OF HISTOGRAM PROCESSING AND EQUALIZATION”
Introduction:
• Histogram:
In an image processing context, the histogram of an image normally refers to
a histogram of the pixel intensity values. This histogram is a graph showing the number
of pixels in an image at each different intensity value found in that image.
• Histogram Equalization:
Histogram equalization is a method in image processing of contrast adjustment using
the image's histogram.
Lab Objectives:
• The objective of this lab is to understand the concept of histogram of an Image and to
perform image enhancement using histogram equalization of an Image
Mathematical Steps:
In Lab Tasks:
Task#01: Write a MATLAB code to plot the histogram of a gray scale image
Task Description:
In this task we take an image and code gives the histogram of an image by finding the intensity
levels and graph is displayed.
