Human detection using stereo vision<\/p><\/div>\n
Human detection is a key process when trying to achieve a fully automated social robot. Currently most approaches to human detection by a social robot are based on visual features derived from the human faces. These approaches have one major impediment, in order to be detected the user must be facing the camera. This thesis presents a new approach based on novel features provided by an attention system using the entire human body. A human detection system is constructed in order to test the proposed features.<\/p>\n

This system is composed of four modules: (i) Preprocessing, (ii) stereo-based segmentation, (iii) novel attention-based feature extraction, and (iv) neural network-based classification. The results show that the proposed system: (i) Improves the detection rate and decreases the false positive rate compared to previous works based on different visual features. (ii) Detects people in different poses, obtaining a considerably higher detection rate than commonly used human detection modules in social robots which often rely on face detection; (iii) Runs in real time; and (iv) Operates on board a mobile platform such as a social robot.<\/p>\n
