The "Not Hotdog" app, created by See Food Inc., set off a wave of discussions within the AI community. While seemingly straightforward, the technology behind this app is anything but simple. Despite its limited scope at the application level, it marked a significant milestone in the evolution of human AI. As reported earlier by 36Kr, the app's success demonstrated the potential of image-based AI systems.
MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) has now taken this concept further with their latest research initiative. The team aims to develop a food recognition system capable of identifying ingredients directly from videos of food preparation. Dubbed pic2recipe, this innovative tool leverages computer neural networks to analyze gourmet photos shared on social media platforms. By doing so, it not only identifies the type of dish but also provides insights into the uploader's lifestyle, health habits, and culinary preferences.
The foundation of the pic2recipe system lies in the Food-101 dataset, an algorithm developed by Swiss researchers in 2014. This dataset comprises over 101,000 images of food items, which are cross-referenced against the Recipe1M database. The Recipe1M database draws most of its data from popular recipe websites like All Recipes and Food.com.
Despite these advancements, the technology remains far from perfect. Currently, the system boasts an accuracy rate of approximately 65%. One of the primary challenges faced by the team is the variability in how food is presented in photographs. Co-developer Nick Hynes noted that factors such as angle, distance, lighting, and even the arrangement of the food can significantly impact recognition outcomes. Furthermore, when the same dish appears across multiple recipes, the system's error rate tends to rise.
Interestingly, the current iteration of the system performs better with baked goods than other types of cuisine.
With the global food industry valued at trillions of dollars, there is immense potential for AI applications in this domain. From retail to dining experiences, social media platforms, and beyond, food-related ventures continue to attract substantial investments. If MIT's technology matures, the possibilities for integration into various sectors could be vast. Imagine using this system to enhance personalization in meal planning apps, or even to assist chefs in creating new recipes based on real-time consumer feedback.

As the field progresses, further refinements will undoubtedly lead to more robust and versatile solutions. Whether it's helping individuals make healthier eating choices or streamlining operations in professional kitchens, AI-powered food recognition holds immense promise for shaping our future relationship with food.
