Let us know how this access is important for you. Many UC-authored scholarly publications are freely available on this site because of the UC's open access policies. We highlight a range of potential applications of our model, list some limitations, and provide MATLAB resources for researchers to utilize our face space, including the ability to customize the demographic makeup of the face space, add new faces, and produce morphs and caricatures. Typically, just a head or face mesh will have a TRI file, for morphs like facial expressions. Participants successfully recognized approximately 50% of celebrity faces based on the PFD models, comparable to performance based on FaceGen Modeler (also 50% correct). These files are generated by the FaceGen Customizer, and their data describes how vertices in the SAM's gr2 are translated to morph the gr2 into a target shape. In Experiment 2, we conduct a celebrity recognition task, comparing performance on PFDs to performance on untextured renderings from FaceGen Modeller. In Experiment 1 we show that PFDs produce a reliable 'inversion effect' in short-term recognition, a hallmark of holistic processing. We present data from two behavioral experiments to validate our model and demonstrate its applicability. Each front-view face image is manually coded with 85 landmark points that are then normalized and rendered with MATLAB (MathWorks, Natick, MA) tools to produce a smooth, parameterized face line drawing. Our model is based on a demographically diverse sample of 400 faces (200 female, 200 male 100 East Asian/Pacific Islander, 100 Latinx/Hispanic, 100 black/African-American, and 100 white/Caucasian) compiled from several face databases (including FERET face recognition technology and the Chicago Face Database). This constraint has led to negative consequences for underrepresented populations, such as impairments in automatized identity recognition of certain demographic groups. A review of existing face space models (including FaceGen Modeller, Synthetic Faces, MPI, and active appearance model) indicates that current models are constrained by their reliance on ethnically homogeneous face databases. We introduce a novel face space model-parametric face drawings (or PFDs)-to generate schematic, though realistic, parameterized line drawings of faces based on the statistical distribution of human facial features.
