최근 딥러닝에 대한 관심이 증가하면서 이를 이용한 다양한 분야에서 연구가 진행되고 있다. 그러나 딥러닝 기반의 생성 모델을 이용하는 폰트의 자동 생성 연구들은 로마자 및 한자와 같은 몇 언어들에 국한되어 연구되고 있다. 한글 폰트 디자인은 매우 큰 시간과 비용이 들어가는 작업으로, 딥러닝을 이용하면 손쉽게 생성할 수 있다. 한글 폰트를 생성하는 연구는 딥러닝 기반의 생성 모델들과 발맞추기 위해 프로세스 자동화 관점에서 한글 폰트 데이터셋을 준비하는 것이 중요하다. 이를 위하여 본 논문에서는 딥러닝 기반의 한글 폰트 연구를 위한 한글 폰트 데이터셋을 제안하고. 그 데이터셋을 구성하는 방법을 기술한다. 본 논문에서 제안하는 한글 폰트 데이터셋을 기반으로 딥러닝 한글 폰트 생성 어플리케이션에 적용하는 과정을 통해 제안하는 데이터셋 구성의 유용성을 보인다.

In recent years research on automatic font generation with machine learning mainly focus on using transformation-based methods, in comparison, generative model-based methods of font generation have received less attention. Transformation-based methods learn a mapping of the transformations from an existing input to a target. This makes them ambiguous because in some cases a single input reference may correspond to multiple possible outputs. In this work, we focus on font generation using the generative model-based methods which learn the buildup of the characters from noise-to-image. We propose a novel way to train a conditional generative deep neural model so that we can achieve font style control on the generated font images. Our research demonstrates how to generate new font images conditioned on both character class labels and character style labels when using the generative model-based methods. We achieve this by introducing a modified generator network which is given inputs noise, character class, and style, which help us to calculate losses separately for the character class labels and character style labels. We show that adding the character style vector on top of the character class vector separately gives the model rich information about the font and enables us to explicitly specify not only the character class but also the character style that we want the model to generate.

Hangul is a language that is composed of initial, medial, and final syllables. It has 11,172 characters. For this reason, the current method of designing all the characters by hand is very expensive and time-consuming. In order to solve the problem, this paper proposes an automatic Hangul font generation system and evaluates the standards for mapping Hangul characters to produce an effective automated Hangul font generation system. The system was implemented using character generation engine based on deep learning CycleGAN. In order to evaluate the criteria when mapping characters in pairs, each criterion was designed based on Hangul structure and character shape, and the quality of the generated characters was evaluated. As a result of the evaluation, the standards designed based on the Hangul structure did not affect the quality of the automated Hangul font generation system. On the other hand, when tried with similar characters, the standards made based on the shape of Hangul characters produced better quality characters than when tried with less similar characters. As a result, it is better to generate automated Hangul font by designing a learning method based on mapping characters in pairs that have similar character shapes.

In a pop song, the creator's intention is communicated to the user through music and lyrics. Lyric meaning is as important as music, but in most cases lyrics are delivered to users in a static form without non-verbal cues. Providing lyrics in a static text format is inefficient in conveying the emotions of a music. Recently, lyrics video with kinetic typography are increasingly provided, but producing them requires expertise and a lot of time. Therefore, in this system, the emotions of the lyrics are found through the analysis of the text of the lyrics, and the deep learning model is trained with the data obtained by converting the melody into a Mel-spectrogram format to find the appropriate emotions for the music. It sets properties such as motion, font, and color using the emotions found in the music, and automatically creates a kinetic typography video. In this study, we tried to enhance the effect of conveying the meaning of music through this system.
