Implementation of Prewitt Edge Detection and Backpropagation Algorithm for the Introduction of Palembang Songket Motifs

Introduction

Indonesia is a country rich in cultural heritage, with a diverse array of traditional fabrics that are unique to each region. One of the most well-known and revered traditional fabrics is the Songket Palembang, which is famous for its intricate and diverse motifs. However, despite its popularity, public knowledge of the various Songket Palembang fabric motifs remains limited. This is where the application of modern technology, such as artificial neural networks (ANN), becomes highly relevant.

Background

The use of artificial neural networks (ANN) has become increasingly popular in recent years, particularly in the field of image recognition and pattern classification. One of the key advantages of ANN is its ability to learn from data and improve its accuracy over time. In the context of image recognition, ANN can be trained to recognize patterns and features in images, making it an ideal tool for applications such as object detection, facial recognition, and image classification.

Methodology

This study focuses on the use of Prewitt edge detection operators and backpropagation algorithms to develop an application that can recognize Palembang Songket fabric motifs. The Prewitt edge detection operator is a widely used technique in image processing that helps to extract the edge features of an image. The backpropagation algorithm, on the other hand, is a technique commonly used in machine learning that allows the model to learn from mistakes made during the training process and gradually improve its accuracy.

Prewitt Edge Detection

Prewitt edge detection is a technique that helps to extract the edge features of an image. The edges of an image are the boundaries between different regions or objects, and they are crucial information for understanding the visual characteristics of an object. In the context of image recognition, the edges of an image can be used as features that will be recognized by the model. The Prewitt edge detection operator works by convolving the image with a set of filters that are designed to detect edges in different directions.

Backpropagation Algorithm

The backpropagation algorithm is a technique commonly used in machine learning that allows the model to learn from mistakes made during the training process and gradually improve its accuracy. The algorithm works by propagating the error backwards through the network, adjusting the weights and biases of the model to minimize the error. The backpropagation algorithm is a key component of many machine learning models, including neural networks, and is widely used in applications such as image recognition, natural language processing, and speech recognition.

Experiment and Results

In this study, the authors conducted an experiment with a learning rate setting of 0.5 and a maximum of 200 EPOCH. The test results showed an accuracy of 72.7% with test data consisting of 16 Songket motif images and 6 non-Songket images. These results indicate that the method used is effective in recognizing and distinguishing Palembang Songket motifs.

Analysis

The use of edge detection techniques such as Prewitt is an important step in image processing, especially in the context of pattern recognition. Peripheral detection helps in identifying boundaries in the image, which is crucial information to understand the visual characteristics of an object. In this case, the edges of complex Songket motifs can be extracted and used as features that will be recognized by the model.

After the edge feature is extracted, the backpropagation algorithm will be used to train the nerve network model. Backpropagation is a technique commonly used in machine learning, where the model will learn from mistakes made during the introduction process and gradually improve itself to increase accuracy. The training process with the right learning rate is very influential on the speed and effectiveness in achieving the desired accuracy.

Conclusion

With a combination of Prewitt edge detection and backpropagation algorithm, this study shows great potential in recognizing Palembang Songket motifs automatically. Although the results of accuracy of 72.7% are good enough, there is still room for improvement. Further research can explore other techniques in processing images and machine learning to achieve a higher level of accuracy. Thus, the application developed is not only useful for preserving knowledge about Palembang Songket fabric motifs, but can also increase public interest in Indonesian traditional fabrics.

Future Work

There are several areas that can be explored in future research, including:

Improving the accuracy of the model: The current accuracy of 72.7% is good, but there is still room for improvement. Further research can explore other techniques in processing images and machine learning to achieve a higher level of accuracy.
Expanding the dataset: The current dataset consists of 16 Songket motif images and 6 non-Songket images. Further research can expand the dataset to include more images and improve the accuracy of the model.
Applying the model to other applications: The model developed in this study can be applied to other applications, such as object detection, facial recognition, and image classification.
