How to make a fast and precise recognition of body shapes has become a hot spot in the field of body shape research. In order to improve the fitting of garment on hips, the characteristic of young females＇ hip shapes was taken into consideration and a recognition model for young females＇ hip shapes using probabilistic neural network （PNN） method based on 3-D body measurement was constructed. At first, hip size data were acquired based on 3-D body measurement, of which, 6 typical indices were extracted, and hip shapes were classified; then probabilistic neural network （PNN） method was introduced, and a model, whose input layer contained six typical indices, output layer was shape types and pattern layer was radial basis function （ RBF）, was constructed; the simulation was completed by MatLab R2009a, and an exact and steady model was obtained by training; and finally, the accuracy of the model was tested. The result showed that the model had excellent performance with high prediction accuracy, so that it could provide a new method to recognize young females＇ hip shapes and widen applicability of PNN method as well.
