Automated Food Recognition and Nutritional Estimation With a Personal Mobile Electronic Device

摘要

A food recognition assistant system includes technologies to recognize foods and combinations of foods depicted in a digital picture of food. Some embodiments include technologies to estimate portion size and calories, and to estimate nutritional value of the foods. In some embodiments, data identifying recognized foods and related information are generated in an automated fashion without relying on human assistance to identify the foods. In some embodiments, the system includes technologies for achieving automatic food detection and recognition in a real-life setting with a cluttered background, without the images being taken in a controlled lab setting, and without requiring additional user input (such as user-defined bounding boxes). Some embodiments of the system include technologies for personalizing the food classification based on user-specific habits, location and/or other criteria.

主权项

1. A food recognition assistant embodied in one or more non-transitory machine accessible storage media, the food recognition assistant comprising instructions executable by one or more processors to cause a personal mobile electronic device to:
receive a single digital image; execute one or more feature detection algorithms using at least two different scales of resolution to determine one or more salient regions of the image without relying on a user to specify the one or more salient regions, the one or more salient regions depicting food; execute a semantic reasoning technique to identify a food present in the image by comparing a characteristic of the one or more salient regions with a characteristic of a known food; and by an output device of the personal mobile electronic device, output a name of the identified food.
