Introduction

In today's digital age, high-quality images are essential for various applications, including medical, art, and industry. However, low-quality digital images often contain defects, noise, blurred colors, or non-smooth surfaces, making them difficult to interpret. This is because the information conveyed through the image is reduced, affecting the user's understanding of the image. To overcome this problem, special image processing applications are needed that can improve image quality.

Image Processing Applications

Image processing applications are designed to enhance image quality by reducing noise and smoothing irregularities in the image. There are two primary methods used to reduce noise: filtering intensity and frequency filtering. Meanwhile, to smooth the image, three methods are applied: average filtering (mean filtering), median filtering (median filtering), and filtering mode (mode filtering).

Filtering Intensity

Filtering intensity is a method that works by changing the intensity of the pixel color in the image. By using this technique, the noise in the image can be minimized without eliminating important details. This is particularly useful when the image contains unwanted high-frequency noise. Filtering intensity is a simple yet effective method for reducing noise in images.

Frequency Filtering

Frequency filtering is a technique that involves image processing in the frequency domain. By separating high-frequency components (which usually contain noise) from low-frequency components (which contain important information), we can restore image quality in a more efficient way. Frequency filtering is a powerful tool for reducing noise and improving image quality.

Average Filtering (Mean Filtering)

Average filtering, also known as mean filtering, is a method that smooths the image by taking the average pixel value around it. Although effective in reducing noise, this method can cause loss of detail in the image, making it less ideal for images that require accuracy. Average filtering is a simple method that can be used to reduce noise in images, but it may not be the best choice for all applications.

Median Filtering (Median Filtering)

Median filtering, also known as median filtering, is a method that uses the median value of the surrounding pixel. This approach is very effective in reducing noise without eliminating important details, especially in imagery with defects. Median filtering is a powerful tool for reducing noise and improving image quality.

Filtering Mode (Mode Filtering)

Filtering mode is a method that works by replacing the pixel value with the most common value (mode) around it. This technique is useful for reducing noise in a discrete image and maintaining relevant information. Filtering mode is a simple yet effective method for reducing noise in images.

Histogram Analysis

After the image is processed using this application, a histogram is created based on the RGB scale to facilitate observation. This histogram allows us to clearly see changes in the number of colors produced due to the application of the screening technique. Histogram analysis is a valuable tool for understanding the changes that occur in the image after going through a filtering process.

Conclusion

Software design for digital image improvement by applying these five screening techniques provides effective solutions to improve image quality. The combination of various image processing methods allows users to get optimal results, both in reducing noise and image refinement. In addition, the use of histograms as an analysis tool helps in understanding more in-depth the changes that occur in the image after going through a filtering process. Thus, this application is a very valuable tool in the world of digital image processing.

Future Work

Future work can focus on improving the application by incorporating more advanced image processing techniques, such as wavelet filtering or non-local means filtering. Additionally, the application can be extended to support more image formats and resolutions. Furthermore, the application can be integrated with other tools, such as image editing software or computer vision libraries, to provide a more comprehensive solution for digital image processing.

Software Design for Digital Image Improvement Using Five Filtering Techniques

Code

import cv2
import numpy as np

# Load the image
img = cv2.imread('image.jpg')

# Apply filtering intensity
filtered_img_intensity = cv2.filter2D(img, -1, np.array([[0, -1, 0], [-1, 5, -1], [0, -1, 0]]))

# Apply frequency filtering
filtered_img_frequency = cv2.filter2D(img, -1, np.array([[0, 1, 0], [1, -4, 1], [0, 1, 0]]))

# Apply average filtering (mean filtering)
filtered_img_average = cv2.filter2D(img, -1, np.array([[1, 1, 1], [1, 1, 1], [1, 1, 1]]))

# Apply median filtering (median filtering)
filtered_img_median = cv2.medianBlur(img, 3)

# Apply filtering mode (mode filtering)
filtered_img_mode = cv2.filter2D(img, -1, np.array([[0, 0, 0], [0, 1, 0], [0, 0, 0]]))

# Create a histogram based on the RGB scale
hist = cv2.calcHist([img], [0], None, [256], [0, 256])

# Display the results
cv2.imshow('Original Image', img)
cv2.imshow('Filtered Image Intensity', filtered_img_intensity)
cv2.imshow('Filtered Image Frequency', filtered_img_frequency)
cv2.imshow('Filtered Image Average', filtered_img_average)
cv2.imshow('Filtered Image Median', filtered_img_median)
cv2.imshow('Filtered Image Mode', filtered_img_mode)
cv2.imshow('Histogram', hist)

# Wait for a key press
cv2.waitKey(0)
cv2.destroyAllWindows()

This code applies the five filtering techniques to an image and displays the results. The histogram is also created and displayed.
