Generating Handwritten Chinese Characters using CycleGAN
Handwriting of Chinese has long been an important skill in East Asia.
However, automatic generation of handwritten Chinese characters poses a great
challenge due to the large number of characters. Various machine learning
techniques have been used to recognize Chinese characters, but few works have
studied the handwritten Chinese character generation problem, especially with
unpaired training data. In this work, we formulate the Chinese handwritten
character generation as a problem that learns a mapping from an existing
printed font to a personalized handwritten style. We further propose DenseNet
CycleGAN to generate Chinese handwritten characters. Our method is applied not
only to commonly used Chinese characters but also to calligraphy work with
aesthetic values. Furthermore, we propose content accuracy and style
discrepancy as the evaluation metrics to assess the quality of the handwritten
characters generated. We then use our proposed metrics to evaluate the
generated characters from CASIA dataset as well as our newly introduced Lanting
calligraphy dataset.Comment: Accepted at WACV 201
Style Transfer and Extraction for the Handwritten Letters Using Deep Learning
How can we learn, transfer and extract handwriting styles using deep neural
networks? This paper explores these questions using a deep conditioned
autoencoder on the IRON-OFF handwriting data-set. We perform three experiments
that systematically explore the quality of our style extraction procedure.
First, We compare our model to handwriting benchmarks using multidimensional
performance metrics. Second, we explore the quality of style transfer, i.e. how
the model performs on new, unseen writers. In both experiments, we improve the
metrics of state of the art methods by a large margin. Lastly, we analyze the
latent space of our model, and we see that it separates consistently writing
styles.Comment: Accepted in ICAART 201
Analysis of Writing Styles on Wood Slips of the Chinese Han Period Using Deep Generative Models
In this paper, we develop a method to analyze the calligraphic styles of wood slips excavated in Northwestern China. Specifically, we propose a method to quantify the degree of collapse of the Chinese characters by measuring the degree of dissociation using a deep generative model. To realize the method, we introduce anomaly detection with generative adversarial networks (AnoGAN), trained by normal data, and then detect abnormal data based on the reconstruction error when those data are input. First, we train the GAN by using images of a character written in Clerical-Script as training data. Next, we calculate the anomaly scores of the characters based on the difference between the Cursive-Script characters and the generated character images and then calculate the degree of collapse. In our experiments, we created datasets consisting of wood slips made in the Han Period and showed that the proposed method could quantify the degree of misalignment between Clerical-Script of neat font and Cursive-Script of scrawl font
