    Car designing tool using multivariate analysis



    We construct novel car designing tool, which helps car designers to design cars efficiently and stimulates their artistic sensibilities. Cars are synthesized by analyzing various existing car body shapes and extracting meaningful attributes that represent the features of these shapes. First, a database of existing cars is created. We analyze all shapes using principal component analysis (PCA), then, gain attributes that indicate the typical features of those car shapes. By manipulating the weight of each attribute in the PCA space, we can create car shapes. Second, by analyzing the features of specific car groups, i.e. manufacturer, genre, era, etc, we discover attributes that discriminate between these groups. We can generate a new type of cars by adding these features onto any existing car i.e. a BMW-like Mercedes.
