System and method for nutrition analysis using food image recognition
First Claim
1. A system using a food recognition device in communication with a database, that determines a nutritional value of a food item, comprising:
- a food container with one or more partitions, the one or more partitions being defined by a boundary outlined by a periphery formed by the food container, wherein the food container receives the food item;
an image capturing device capturing an image of the food container including the received food item; and
the food recognition device, with a processor and a memory, in communication with the image capturing device, configured to;
obtain the image of the food container from the image capturing device, wherein the image includes the received food item;
correct orientation of the obtained image by aligning the boundary in the image with the boundary in a reference food container image stored in the database;
identify a type of the food item by comparing the image of the food item to a reference food image stored in the database; and
determine the nutritional value of the food item based on the type of the food item.

Abstract
The present disclosure provides a system and method for determining a nutritional value of a food item. The system and method utilizes a food container as a model to adjust various types of distortions that exists in an instant image of the food container that retains the food item. The instant image may be compared to the model image of the food container to correct any distortions. The food container includes a boundary which has a predetermined color. The predetermined color of the boundary can be used to adjust the color configuration of the instant image, thereby increasing the accuracy of the food identification.

11. A method to use a system using a food recognition device in communication with a database, that determines a nutritional value of a food item, comprising:
-
capturing, with an image capturing device, an image of a food container, wherein the food container has one or more partitions, the one or more partitions being defined by a boundary outlined by a periphery formed by the food container, wherein the food container receives the food item, the image including the received food item; obtaining, with a food recognition device, the image of the food container from the image capturing device, the image capturing device being in communication with the food recognition device, wherein the image includes the received food item; correcting, with the food recognition device, orientation of the obtained image by aligning the boundary in the image with the boundary in a reference food container image stored in the database; identifying, with the food recognition device, a type of the food item by comparing the image of the food item to a reference food image stored in the database; and determining, with the food recognition device, the nutritional value of the food item based on the type of the food item. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
