Given the reference images and the natural language descriptions, our algorithm correspondingly generates pose and attribute transferred person images. As shown in the left, our algorithm transfers the person pose based on 'He is walking forward to the camera', and also synthesizes shirts of various different colors. Similarly for the right example. AbstractThis paper presents a novel method to manipulate the visual appearance (pose and attribute) of a person image according to natural language descriptions. Our method can be boiled down to two stages: 1) text guided pose generation and 2) visual appearance transferred image synthesis. In the first stage, our method infers a reasonable target human pose based on the text. In the second stage, our method synthesizes a realistic and appearance transferred person image according to the text in conjunction with the target pose. Our method extracts sufficient information from the text and establishes a mapping between the image space and the language space, making generating and editing images corresponding to the description possible. We conduct extensive experiments to reveal the effectiveness of our method, as well as using the VQA Perceptual Score as a metric for evaluating the method. It shows for the first time that we can automatically edit the person image from the natural language descriptions.
We present the full-resolution correspondence learning for cross-domain images, which aids image translation. We adopt a hierarchical strategy that uses the correspondence from coarse level to guide the finer levels. In each hierarchy, the correspondence can be efficiently computed via Patch-Match that iteratively leverages the matchings from the neighborhood. Within each PatchMatch iteration, the Con-vGRU module is employed to refine the current correspondence considering not only the matchings of larger context but also the historic estimates. The proposed GRU-assisted PatchMatch is fully differentiable and highly efficient. When jointly trained with image translation, full-resolution semantic correspondence can be established in an unsupervised manner, which in turn facilitates the exemplar-based image translation. Experiments on diverse translation tasks show our approach performs considerably better than stateof-the-arts on producing high-resolution images.
