Attribute-Guided Sketch-to-Image Generation

<img src="./imgs/problem.png" width="600">

Introduction

Note: Implementation in this repo has been largely outdated. You may refer to my presentation slides for your own implementation.

This is based on one of our prior works on Sketch-to-Image Generation. Freehand sketch can be highly abstract (examples shown below), and learning representations of sketches is not trivial. In contrast to other cross domain learning approaches, like pix2pix and CycleGAN, where a mapping from representations in one domain to those in another domain is learned using translation networks, in Sketch-to-Image Generation, we propose to learn a joint representation of sketch and image.

In this project we intend to add text constraints to sketch-to-image generation, where texts provide the contents and sketches control the shapes. So far, I only tried to add attribute guidance instead of using text embeddings as additional conditions, and this repo demonstrates results on Attribute-Guided Sketch-to-Image Generation.

Experiments

We test our framework with 3 kinds of data, face(CelebA), bird(CUB), and flower(Oxford-102). So far, we have only experimented with face images using attribute vectors as texts information. Here are some preliminary results:

1. Face

We used CelebA dataset, which also provides 40 attributes for each image. Similar to the text information, attributes control the specific details of the generated images. We chose 18 attrbutes for training.

a). Attributes match sketch:

The following images were generated given sketches and the corresponding attriubtes.

b). Attributes mismatch sketch:

The following images were generated given sketches and the random attriubtes. The controlling effects of the attributes are still under improvement.
