Abstract(in English) | Currently, there are 36 million blind people in the whole world. Furthermore, the number of blind people will be expected to increase to 150 million people by 2050. Tactile paving takes a very important role. Many tactile paving is, however, inappropriate. This paper describes a deficient tactile paving detection algorithm from a pedestrian view point video. In this method, firstly, for the first frame of the video, the tactile paving is detected using color thresholding and noise removal. In the subsequent frames, candidates of tactile paving regions are extracted by performing only on the tactile paving region obtained in the previous frame and its surroundings. Furthermore, the final tactile paving region is obtained by merging with the tactile paving extracted by using HOG(Histogram of Oriented Gradients) features with the candidates. Contour tracking and corner detection are performed on the obtained region. Finally, Inappropriate tactile paving is judged based on the contour and corner information. In the proposed method, tactile paving in six different states was judged. |
