Abstract:

This paper addresses the fitting issues for Xinjiang skirts through a study on the size of lower body shape. In order to determine the true shape of hip body accurately, hip data of 220 young Xinjiang females aged 18 to 25 were analyzed. Using the factor analysis and correlation coefficients mergods, 2 factor for clustering were obtained, i.e. back hip length to waist girth ratio, back hip length to hip girth ratio, and 3 hip body types were defined based on the K-means clustering method. On this basis, Python software was used to establish an XGBoost buttock discriminant model. The work involved three parts. The first thing was to compare and analyze different algorithm models and XGBoost was used to evaluate the accuracy, and the highest accuracy reached 98.4%. The second part was to,modify the intermediate skirt prototype for young Xinjiang females, where it was found that the rear hip length was 2.4 cm different from the rear hip length of the standard dress prototype, indicating that the young Xingjiang female hips is larger than that in other regions. Finally, the discriminating algorithm was applied to the data system. The outcome of the research is shown to have improved discrimination efficiency for body size, and the method provides data support for other human related fields.

Key words: young Xinjiang female, hip shape classification, body shape, XGBoost algorithm, skirt prototype correction
