Show HN: Recreate Images with Emojis

This demo allows you to recreate images using emojis. You can provide images or emojis to paint with, and it will attempt to recreate images using emojis.

Much of the code is adopted from the Paint Transformer (https://arxiv.org/abs/2108.03798) paper. In this code base, I treat emojis like “brushes”, and use a Gumbel Softmax-based lookup to choose an emoji to paste to the canvas during training (similar to how attention uses a softmax to select keys during training).
