Abstract
Currently there are many techniques for structural image manipulation,
but most of them can only stretch an object based on some given constraints,
rather than synthesizing an totally structurally-different object whose style is
similar to the source object. In this thesis, we proposed a new method which
by giving source and target structure information of an object, can synthesize
a new object that meets the expected structure of a user, and in the same time,
is stylish-similar to the source object. Given the target structure information,
our system finds a patch from the source object and puts it on the target object
seamlessly by Graphcut, and this step is repeated until the synthesizing
of the target object is complete. During the process, each synthesizing step
may have many possible source patches to choose. To solve this problem, we
consider this process as a dynamic programming that saves the result and cost
of each possibility and use each result to continue the process until completion,
then we choose the best result among these possibility, thus being able
to synthesize a high-quality new object that is stylish-similar to the source
object. In our method, a user only needs to input simple strokes to specify
the structure of an object to manipulate the structure of an object. We demonstrate
many applications to describe how our method can be used in image
manipulation.
