  Designing fonts requires a great deal of time and effort. It requires
professional skills, such as sketching, vectorizing, and image editing.
Additionally, each letter has to be designed individually. In this paper, we
will introduce a method to create fonts automatically. In our proposed method,
the difference of font styles between two different fonts is found and
transferred to another font using neural style transfer. Neural style transfer
is a method of stylizing the contents of an image with the styles of another
image. We proposed a novel neural style difference and content difference loss
for the neural style transfer. With these losses, new fonts can be generated by
adding or removing font styles from a font. We provided experimental results
with various combinations of input fonts and discussed limitations and future
development for the proposed method.
