  In documents and graphics, contours are a popular format to describe specific
shapes. For example, in the True Type Font (TTF) file format, contours describe
vector outlines of typeface shapes. Each contour is often defined as a sequence
of points. In this paper, we tackle the contour completion task. In this task,
the input is a contour sequence with missing points, and the output is a
generated completed contour. This task is more difficult than image completion
because, for images, the missing pixels are indicated. Since there is no such
indication in the contour completion task, we must solve the problem of missing
part detection and completion simultaneously. We propose a Transformer-based
method to solve this problem and show the results of the typeface contour
completion.
