Abstract
In an embodiment, a method for estimating a composition of food includes: receiving a first three-dimensional (3D) image; identifying food in the first 3D image; determining a volume of the identified food based on the first 3D image; and estimating a composition of the identified food using a millimeter-wave radar.
Claims31
A method for estimating a composition of food, the method comprising:
- receiving a first 3D image;
- identifying food in the first 3D image;
- determining a volume of the identified food based on the first 3D image;

- estimating a composition of the identified food using a millimeter-wave radar.
2 more elements
A mobile device comprising:
- a 3D imaging sensor configured to generate a first 3D image;
- a millimeter-wave radar configured to transmit radar signals and receive reflected radar signals;
- and
- a processor configured to:
- identify food in the first 3D image;
- determine a volume of the identified food based on the first 3D image;

5 more elements
A system comprising:
- a time-of-flight sensor;
- a camera;
- and
- a millimeter-wave radar configured to transmit radar signals and receive reflected radar signals;
- and
- a processor configured to:

8 more elements
A method for estimating a composition of food, the method comprising:
- receiving radar data from an ADC of a millimeter-wave radar;
- preprocessing the received radar data to generate a radar image;
- generating a measurement vector based on the radar image;
