Body circumference fitting model based on coupled linear regression and body type classification

Abstract

Body circumference fitting model is a key technology for personalization in smart manufacturing by the apparel industry. First, the paper collected front and side images plus manual measurement data of 122 young men. Second, through contour recognition and feature point detection of the collected images, the width and thickness of each body part plus the height were estimated. Then, a correlation analysis of these known factors was conducted. The paper proposed that weight was included in initial regression model for circumferences as an additional independent variable along with width and thickness. Finally, according body type classification, a multivariate regression model was established. After validation, the values predicted by the multivariate regression model were within ±1.5 cm of the manual values for 90.9% of the individuals on average. The paper provides theoretical support for body circumference fitting and may also be beneficial to the development of the smart manufacturing of garments.
