Identification of Braille Letters Using Deep Convolutional Neural Network on the Image of Embossed Braille

Introduction

Braille is a vital written communication tool for blind individuals to interact with each other. This tactile writing system consists of a pattern of raised dots produced on special paper, enabling blind people to gain knowledge and information through their sense of touch. However, understanding Braille is not an easy task, especially for those unfamiliar with this system. In Indonesia, education about Braille has not been part of the curriculum, resulting in a lack of experience and knowledge about it among the general public. This creates obstacles in communication between blind individuals and the general public.

The Importance of Braille Education

Braille education is essential for blind individuals to access information and participate in society. However, the lack of Braille education in Indonesia has hindered the development of this vital skill. Many blind individuals struggle to communicate effectively with the general public, leading to social isolation and limited access to education and employment opportunities. To address this issue, this research aims to develop a digital image processing technology using the Deep Convolutional Neural Network (DCNN) method to help individuals who do not understand Braille to comprehend the contents of Braille documents.

Utilization of Deep Learning in Processing Braille Image

Deep learning is a subfield of machine learning that offers a very effective solution in image processing. DCNN, as one of the architectures of deep learning, has the ability to recognize complex patterns in images. In the context of Braille, the advantage of DCNN lies in its ability to learn from broad image data, enabling it to recognize Braille patterns with high accuracy.

The image processing process carried out in this study includes several techniques:

  1. Grayscaling: Changing color images to grayscale to simplify processing and reduce computing loads.
  2. Filtering: Eliminating noise in the picture to improve image quality before further processing.
  3. Contrast Enhancement: Increasing image contrast to make the details of the Braille point more clearly visible.
  4. Morphological Operation: Used to improve the shape of the Braille point, making it easier to recognize by the system.
  5. Resizing: Changing the size of the image to meet the input required by the DCNN model.

Deep Convolutional Neural Network (DCNN) Architecture

The DCNN architecture used in this study consists of several layers:

  1. Convolutional Layer: This layer is responsible for extracting features from the input image.
  2. Activation Function: This layer applies an activation function to the output of the convolutional layer to introduce non-linearity.
  3. Pooling Layer: This layer reduces the spatial dimensions of the feature maps to reduce the number of parameters and improve computational efficiency.
  4. Fully Connected Layer: This layer is responsible for classifying the output of the previous layers.

Results and Conclusions

The test results from this study show that the proposed method can identify Braille images with an accuracy level of 99.63%. This figure is very promising and shows the great potential of deep learning technology in helping blind individuals to communicate better and facilitate interactions with the general public.

Thus, the application of this method not only serves to facilitate the understanding of Braille documents but also contributes greatly to increasing inclusiveness for the blind in everyday life. This study opens the way for further development in processing images and other associated technologies that can provide significant benefits for persons with disabilities.

Future Directions

This study has several potential applications in the field of assistive technology for the blind. Some possible future directions include:

  1. Development of a Braille Recognition System: This system can be used to recognize Braille text in real-time, enabling blind individuals to communicate more effectively with the general public.
  2. Image Processing for Other Disabilities: This study can be extended to develop image processing techniques for other disabilities, such as visual impairments or hearing impairments.
  3. Development of a Braille Education Platform: This platform can be used to provide Braille education to blind individuals, enabling them to access information and participate in society more effectively.

Conclusion

In conclusion, this study has demonstrated the effectiveness of deep learning technology in identifying Braille images. The proposed method has achieved an accuracy level of 99.63%, showing the great potential of deep learning technology in helping blind individuals to communicate better and facilitate interactions with the general public. This study opens the way for further development in processing images and other associated technologies that can provide significant benefits for persons with disabilities.
