Mastering Image Processing Assignments: A Step-by-Step Guide
Permalink   


Welcome, aspiring image processing wizards! Today, we embark on a journey to unravel the secrets of a challenging university-level image processing assignment. We'll explore the intricacies of a fascinating topic and provide you with a comprehensive guide to ace your assignment.

Assignment Question:

"Enhance the Contrast of a Grayscale Image using Histogram Equalization."

Understanding the Concept

Before we dive into the practical aspects, let's comprehend the fundamental concept behind histogram equalization. In simple terms, it's a technique used to enhance the contrast of an image by redistributing its intensity values. This ensures a broader range of intensities is utilized, resulting in a more visually appealing and vibrant image.

Step-by-Step Guide

Now, let's break down the process into simple steps that will help you complete your image processing assignment successfully.

Step 1: Load the Grayscale Image

Start by obtaining a grayscale image. This could be an image provided in your assignment or any grayscale image you find intriguing.

import cv2

import matplotlib.pyplot as plt

 

# Load the image

image = cv2.imread('grayscale_image.jpg', cv2.IMREAD_GRAYSCALE)

 

# Display the original image

plt.imshow(image, cmap='gray')

plt.title('Original Grayscale Image')

plt.show()

Step 2: Compute the Histogram

Next, compute the histogram of the image. This will give you insights into the distribution of intensity values.

# Calculate histogram hist, bins = np.histogram(image.flatten(), 256, [0, 256]) # Plot the histogram plt.plot(hist, color='black') plt.xlabel('Pixel Intensity') plt.ylabel('Frequency') plt.title('Histogram of the Grayscale Image') plt.show()

Step 3: Perform Histogram Equalization

Apply the histogram equalization algorithm to enhance the contrast of the image.

# Apply histogram equalization equ = cv2.equalizeHist(image) # Display the enhanced image plt.imshow(equ, cmap='gray') plt.title('Enhanced Grayscale Image') plt.show()

Step 4: Compare the Results

Compare the original and enhanced images to observe the improvement in contrast.

# Display the original and enhanced images side by side

plt.subplot(121), plt.imshow(image, cmap='gray'), plt.title('Original Image')

plt.subplot(122), plt.imshow(equ, cmap='gray'), plt.title('Enhanced Image')

plt.show()
