Estimation of food volume and carbs

A system for estimating carbs content of food, said system comprising instructions which when performed by a processor causes the system to operate to:

• identify a movement of an image acquisition component between a first image of the food and a second image of the food, the second image having been acquired with the food highlighted with a projected light pattern;
• correct the first image and/or the second image by an operation which compensates movements of the image acquisition component throughout an image acquisition operation based on artifacts to get first and second images of a corrected pair of images;
• subtract the first and second images of the corrected pair of images;
• identify the projected light pattern based upon the subtraction of the first and second images of the corrected pair of images;
• compute the tridimensional shape and the volume of the food given the deformations of the projected light pattern;
• make segmentation and recognition of the food from the first image;
• and
• compute the carbs content of the food based upon the volume, segmentation and recognition of food via use of nutritional databases.
