Volume Extraction from Body Scans for Bra Sizing

Abstract

We present a novel method for bra sizing based on surface scan data. While the current standard of finding the proper size for brassieres is based on only two 1-dimensional measurements, our approach takes the entire shape information into account. We propose to use the breast's volume as a good approximation for that shape. To compute the breast volume we introduce a robust and automatic algorithm based on measuring the volume difference of a torso with and without the breasts. Finally, we compare our novel sizing strategy to the traditional sizing of bras. We will show a better distribution across the population of test-subjects. Using the surface scan data in combination with our volume based sizing approach we can furthermore generate mean body shapes for every bra size which is of great benefit for bra development.
