Show me your body: Gender classification from still images

In this work, we investigate the problem of predicting gender from still images using human metrology. Since the values of the anthropometric measurements are difficult to be estimated accurately from state-of-the-art computer vision algorithms, ratios of anthropometric measurements were used as features. Additionally, since several measurements will not be available at test time in a real-life scenario, we opted for the Learning Using Privileged Information (LUPI) paradigm. During training, we used as features, ratios from all the available anthropometric measurements, whereas at test time only ratios of measurable (i.e., observable) quantities were used. We show that by using the LUPI framework, the estimation of soft biometric characteristics such as gender is possible. Gender classification from human metrology is also tested on real images with promising results.
