Im2Vec: Synthesizing Vector Graphics without Vector Supervision
Pradyumna Reddy, Michael Gharbi, Michal Lukac, Niloy J. Mitra

TL;DR
Im2Vec introduces a neural network that synthesizes complex vector graphics from raster images without requiring explicit vector supervision, leveraging a differentiable rasterization pipeline for training.
Contribution
The paper presents a novel method for generating vector graphics using indirect supervision, avoiding the need for large-scale vector datasets or explicit vector annotations.
Findings
Outperforms state-of-the-art SVG-VAE and DeepSVG models.
Capable of generating diverse vector graphics with varying topologies.
Successfully applied to datasets without groundtruth vector representations, like MNIST.
Abstract
Vector graphics are widely used to represent fonts, logos, digital artworks, and graphic designs. But, while a vast body of work has focused on generative algorithms for raster images, only a handful of options exists for vector graphics. One can always rasterize the input graphic and resort to image-based generative approaches, but this negates the advantages of the vector representation. The current alternative is to use specialized models that require explicit supervision on the vector graphics representation at training time. This is not ideal because large-scale high quality vector-graphics datasets are difficult to obtain. Furthermore, the vector representation for a given design is not unique, so models that supervise on the vector representation are unnecessarily constrained. Instead, we propose a new neural network that can generate complex vector graphics with varying…
