<h2>Abstract</h2> | ||
<p> | ||
The writing style of the same writer varies from instance to instance in Arabic and English handwritten digit recognition, making handwritten digit recognition challenging. | ||
Currently, deep learning approaches are applied in many applications, including convolutional neural networks (CNNs) modified to produce other models, such as local binary convolutional neural networks (LBCNNs). | ||
An LBCNN is created by fusing a local binary pattern (LBP) with a CNN by reformulating the LBP as a convolution layer called a local binary convolution (LBC). | ||
However, LBCNNs suffer from the random assignment of 1, 0, or -1 to LBC weights, making LBCNNs less robust. | ||
Nevertheless, using another LBP-based technique, such as center-symmetric local binary patterns (CS-LBPs), can address such issues. | ||
In this paper, a new model based on CS-LBPs is proposed called center-symmetric local binary convolutional neural networks (CS-LBCNN), which addresses the issues of LBCNNs. | ||
Furthermore, an enhanced version of CS-LBCNNs called threshold center-symmetric local binary convolutional neural networks (TCS-LBCNNs) is proposed, which addresses another issue related to the zero-thresholding function. | ||
Finally, the proposed models are compared to state-of-the-art models, proving their ability by producing a more accurate and significant classification rate than the existing LBCNN models. | ||
For the bilingual dataset, the TCS-LBCNN enhances the accuracy of the LBCNN and CS-LBCNN by 0.15% and 0.03%, respectively. | ||
In addition, the comparison shows that the accuracy acquired by the TCS-LBCNN is the second-highest using the MNIST and MADBase datasets. | ||

<h2>Research Aims and Objectives</h2> | ||
<p>This research aims to enhance the performance of LBP-based convolutional neural networks on the automatic recognition of bilingual handwriting. The objectives of the research are as follows:</p> | ||
<ol> | ||
<li>To introduce center-symmetric local binary convolutional neural networks (CS-LBCNNs) to overcome the illumination transformation and the negative effect of the random weights of LBCNNs.</li> | ||
<li>To enhance the CS-LBCNN by applying a nonzero thresholding function that allows the model to extract more distinguished features, called the threshold center-symmetric local binary convolutional neural network (TCS-LBCNN) model.</li> | ||
<li>To validate the models with other benchmark models.</li> | ||
</ol> | ||
