Introduction

Colon cancer, also known as colorectal cancer, is a type of malignant tumor that appears in the colon or rectum. At an advanced stage, this cancer can spread to other organs of the body, making early detection and proper treatment crucial. One way to examine colon cancer is through colonoscopy, a procedure that involves the installation of flexible tubes equipped with video cameras through the rectum, allowing doctors to see and analyze the inside of the large intestine directly.

The Importance of Early Detection and Accurate Diagnosis

However, the process of diagnosis through colonoscopy requires a long time and high skills from a doctor to accurately detect the stage of colon cancer based on the resulting image. Therefore, the development of automatic methods to classify colonoscopy images becomes very important in helping to achieve a faster and more precise diagnosis.

Linear Discriminant Analysis (LDA) for Colonoscopy Image Classification

In this study, the Linear Discriminant Analysis (LDA) was proposed as a method for automatically classifying colonoscopy images. The classification process begins with the preprocessing stage, where the image is converted into grayscale format. Furthermore, segmentation is carried out using the OTSU Thresholding method, which aims to separate relevant objects in the image. After that, the image that has been segmented is converted again into grayscale imagery.

Feature Extraction using Gray Level Co-Occurrence Matrix (GLCM)

To increase accuracy in classification, important features are extracted using the Gray Level Co-Occurrence Matrix (GLCM). The six features analyzed include:

Energy: a measure of the uniformity of the image
Sum of Square: a measure of the variance of the image
Inverse Different Moment (IDM): a measure of the contrast of the image
Maximum Probability: a measure of the most frequent pixel value in the image
Homogeneity: a measure of the similarity of the image
Dissimilarity: a measure of the difference between the image and a reference image

Results and Discussion

The results of the study showed that the LDA method was able to classify the colonoscopy image with an accuracy reaching 92.85%. This analysis is very useful in the medical context, as it provides a solution that allows doctors to identify the stage of colon cancer more efficiently. The accuracy of this classification can accelerate clinical decision making, which in turn can increase the possibility of patients to get appropriate treatment quickly.

Conclusion and Future Research Directions

Further research needs to be done to increase the dataset and explore the use of other algorithms that may be more efficient in image classification, so that it can help more in the treatment of colorectal cancer in the future. The implementation of techniques such as the Linear Discriminant Analysis in the colonoscopy image classification can be a significant advanced step in the medical world, especially in early detection of colon cancer. This shows the importance of technological integration with medical practice to improve patient health outcomes.
