Introduction

In today's digital era, facial recognition technology has become increasingly relevant for various applications, including security, authentication, and information technology. The accuracy and speed of facial recognition systems are crucial for their effectiveness. This study discusses the application of the Hybridization of the Learning Vector Quantization (LVQ) algorithm with self-organizing for face introduction using webcam. The goal is to improve the accuracy and speed of facial recognition systems.

Background

Facial recognition technology has been widely used in various fields, including security, authentication, and information technology. However, the accuracy and speed of facial recognition systems are still a challenge. The Learning Vector Quantization (LVQ) algorithm is a type of neural network that has been widely used for facial recognition. However, the LVQ algorithm has its limitations, including the need for a large amount of training data and the risk of overfitting. To overcome these limitations, this study proposes the hybridization of the LVQ algorithm with the Kadalah algorithm.

Methodology

The methodology of this study involves the following steps:

Data Collection: The data used in this study consists of facial digital images obtained through the camera. The images will be divided into two sets: a learning data set and a testing data set.
Preprocessing: The face images need to be processed first (preprocessing) to be ready to be used as input in the network. This preprocessing process is divided into four steps:

Reading Image: Take the face image of the existing source.
GrayScaling: Changing the color image into a grayscale image to simplify the data to be processed.
Edge Detection with Sobel Operator: Applying the edge detection method to accentuate the boundaries of the object in the image.

Hybridization: The Kadalah algorithm is used to determine the initial weight, which is then included in the LVQ algorithm. The final result of this process is a weight that is ready to be used to recognize the face.
Testing: The testing data set is used to evaluate the performance of the hybrid algorithm.

Results

The test results show that the percentage of successful face recognition for the LVQ algorithm reached 57.03%, Kohsien was 52.59%, and Hybrid recorded the highest number of 68.88%. In terms of recognition process time, the LVQ algorithm requires an average of 2.64 seconds, a 2.61 second, and hybrid is only 2.59 seconds.

Discussion

The results of this study show that the hybrid algorithm shows excellence in accuracy when compared to the Kohsen algorithm, which is 16.29%. In addition, in terms of the speed of the introduction process, the hybrid algorithm is more efficient than the LVQ and Kohsien with a significant time difference, which is 0.05 seconds faster than LVQ and 0.02 seconds than Kohsien.

Conclusion

The hybridization of the LVQ algorithm with the Kadalah algorithm is a promising approach for improving the accuracy and speed of facial recognition systems. The use of webcam as a data acquisition tool is a practical and efficient step, given the number of devices available today. This allows the system to be applied in real situations with uncomplicated use of devices. In the increasingly advanced digital era, face recognition technology becomes very relevant, both for security, authentication, and various other applications in the field of information technology. With the application of this hybrid algorithm, not only increases the accuracy and speed of facial recognition, but also opens the way for further research and development in this field.
