Ketchup As You Like: Drawing Editor for Foods

Omelet rice is a popular Japanese dish made from an egg omelet filled with rice. There is a culture of freely drawing patterns or messages on it with tomato ketchup. The advantage of this practice is that it is easy to create originality and express creativity. We believe that utilizing this advantage would be possible to generate original food models in VR space easily. Therefore, we introduce a web-based real-time application called “Ketchup As You Like”, which allows users to freely draw with ketchup on an omelet image. This application is able to generate omelet images with realistic ketchup patterns. The image generation used in “Ketchup As You Like” is created by combining CNN-based segmentation and generative adversarial networks (GAN). Demo video is available at https://youtu.be/m6AjwEY6Jp8
