  We present a generative model for controllable person image synthesis,as
shown in Figure , which can be applied to pose-guided person image synthesis,
$i.e.$, converting the pose of a source person image to the target pose while
preserving the texture of that source person image, and clothing-guided person
image synthesis, $i.e.$, changing the clothing texture of a source person image
to the desired clothing texture. By explicitly establishing the dense
correspondence between the target pose and the source image, we can effectively
address the misalignment introduced by pose tranfer and generate high-quality
images. Specifically, we first generate the target semantic map under the
guidence of the target pose, which can provide more accurate pose
representation and structural constraints during the generation process. Then,
decomposed attribute encoder is used to extract the component features, which
not only helps to establish a more accurate dense correspondence, but also
realizes the clothing-guided person generation. After that, we will establish a
dense correspondence between the target pose and the source image within the
sharded domain. The source image feature is warped according to the dense
correspondence to flexibly account for deformations. Finally, the network
renders image based on the warped source image feature and the target pose.
Experimental results show that our method is superior to state-of-the-art
methods in pose-guided person generation and its effectiveness in
clothing-guided person generation.
