Abstract

Due to the absence of features that may be extracted from face, heading direction estimation for low resolution images is a difficult task and requires the taking into account all information that may be inferred from human body in image, particularly its silhouette. We propose in this paper a set of geometric features extracted from shape head-shoulders, feet and knees shapes which jointly allow the estimation of body direction. Other features extracted from head-shoulders are proposed for heading direction estimation based on body direction. The constraint of camera position related to proposed features is discussed and results of conducted experiments are presented.
