Abstract: We propose a new computer vision problem of subjective baggage-weight estimation by defining the term subjective weight as how heavy the person feels. We propose a method named G2SW (Gait to Subjective Weight), which is based on the assumption that cues of the subjective weight appear in the human gait, described by a 3D skeleton sequence. The method uses 3D locations and velocities of body joints as input and estimates subjective weight using a Graph Convolutional Network. It also estimates human body weight as a sub-task based on the assumption that the strength of a person depends on body weight. For the evaluation, we built a dataset for subjective baggage-weight estimation, consisting of 3D skeleton sequences with subjective weight annotations. We confirmed that the subjective weight could be estimated from a human gait and also confirmed that the sub-task of body weight estimation pulls up the performance of the subjective weight estimation.
