Implementation of Merging Adaptive Median Filter and Gaussian Smoothing Filter to Improve the Quality of Digital Image

Introduction

In today's digital age, digital images have become one of the most commonly used data presentation media. The ease of taking and manipulating digital images has made them a popular choice for various applications, including medical imaging, satellite imaging, and security monitoring. However, digital images often suffer from a decrease in quality due to defects or disturbances, commonly known as noise. Noise in digital images can take the form of Gaussian Noise and Salt and Pepper Noise, which can significantly reduce the clarity of information conveyed by the image. Therefore, a filtering method is necessary to reduce or eliminate this disorder.

The Need for Image Filtering

Image filtering is a crucial step in digital image processing, as it helps to remove noise and improve the overall quality of the image. There are various types of image filters available, each with its own strengths and weaknesses. In this study, we focus on the combination of Adaptive Median Filter and Gaussian Smoothing Filter, two popular filtering methods used to reduce noise in digital images.

Adaptive Median Filter

The Adaptive Median Filter is a type of non-linear filter that is effective in overcoming Salt and Pepper Noise. This filter works by replacing each pixel in the image with the median value of neighboring pixels. The adaptive aspect of this filter allows it to adjust its behavior based on the local characteristics of the image, making it more effective in reducing noise.

Gaussian Smoothing Filter

The Gaussian Smoothing Filter is a type of linear filter that is useful in reducing noise with a Gaussian distribution. This filter works by convolving the image with a Gaussian kernel, which helps to smooth out the image and reduce noise. The Gaussian Smoothing Filter is particularly effective in reducing Gaussian Noise.

Combining Adaptive Median Filter and Gaussian Smoothing Filter

In this study, we aim to analyze the combination of Adaptive Median Filter and Gaussian Smoothing Filter and compare it with each method separately in improving the quality of the image affected by both types of noise. Our results show that the combination of these two filters is ineffective in overcoming Gaussian Noise, but it has been proven to be the most effective method in reducing Salt and Pepper Noise.

Results and Discussion

Our results show that the combination of Adaptive Median Filter and Gaussian Smoothing Filter has a significant potential in reducing Salt and Pepper Noise. The lowest average Mean Squared Error (MSE) value obtained was 3901.66, and the highest Peak Signal-to-Noise Ratio (PSNR) value obtained was 1,258. These results indicate that the combination of these two filters is effective in reducing noise and improving the quality of the image.

However, our results also show that the combination of these two filters is ineffective in overcoming Gaussian Noise. The increase in the value of MSE is higher when compared to the image before filtering, indicating that the combination of these two filters is not effective in reducing Gaussian Noise.

Conclusion

In conclusion, although the combination of Adaptive Median Filter and Gaussian Smoothing Filter is ineffective in overcoming Gaussian Noise, it has been proven to be the most effective method in reducing Salt and Pepper Noise. Further research is still needed to explore parameters and other arrangements that can increase the effectiveness of this filtering method. The results of this study are expected to provide new insights for the development of better digital image processing technology, as well as making a positive contribution to this field as a whole.

Future Research Directions

With the right approach, the combination of this filtering method has the potential to be implemented in various applications, ranging from medical image processing, satellite image analysis, to image processing in the fields of security and monitoring. In the future, it is hoped that there will be further research that can explore the combination of other methods, so that the quality of digital images can be increased significantly and the information contained in it remains intact.

Based on the results of this study, we recommend the following:
