摘要:

有无数的字体具有各种形状和风格。此外,还有许多字体在功能上只有细微的差异。因此,字体识别是一项艰巨的任务。在本文中,我们提出了一种方法来确定是否有任何两个字符是来自同一字体或不。这是困难的,因为字体之间的差异通常小于字母表类别之间的差异。此外,所提出的方法可以与字体一起使用,无论它们是否存在于训练中。为了实现这一点,我们使用了一个卷积神经网络(CNN),用各种字体图像对进行训练。在实验中,网络在各种字体的图像对上进行训练。然后,我们在网络看不到的不同字体集上评估模型。评价的准确度为92.27%。此外,我们还分析了字符类别和字体识别精度之间的关系。

英文摘要:

There are a countless number of fonts with various shapes and styles. In addition, there are many fonts that only have subtle differences in features. Due to this, font identification is a difficult task. In this paper, we propose a method of determining if any two characters are from the same font or not. This is difficult due to the difference between fonts typically being smaller than the difference between alphabet classes. Additionally, the proposed method can be used with fonts regardless of whether they exist in the training or not. In order to accomplish this, we use a Convolutional Neural Network (CNN) trained with various font image pairs. In the experiment, the network is trained on image pairs of various fonts. We then evaluate the model on a different set of fonts that are unseen by the network. The evaluation is performed with an accuracy of 92.27%. Moreover, we analyzed the relationship between character classes and font identification accuracy.
