Claim 0:
1. A computer-implemented method, comprising:
receiving, from a portable device, a two-dimensional (“2D”) body image generated by a 2D camera of the portable device;
processing the 2D body image at a first bottleneck of a neural network to produce a first downsampled feature representation;
processing the first downsampled feature representation with a second bottleneck of the neural network to produce a second downsampled feature representation;
extracting first features from the second downsampled feature representation;
processing the second downsampled feature representation with a third bottleneck of the neural network to produce a third downsampled feature representation;
extracting second features from the third downsampled feature representation;
concatenating at least the first features, the second features, and an output of the neural network to produce concatenated features;
applying a linear function to the concatenated features to determine a body fat measurement representation;
determining a body fat measurement value from the body fat measurement representation; and
presenting, via a display of the portable device, the body fat measurement value.
