“…Limited scenarios are detected by their methods, and the accuracy remains to be promoted. Shuihua Wang et al [10] proposed a zebra crossing recognition based Canny edge detection [12] and Hough Transform. Similarly, Chen Ning et al [13] proposed a zebra crossing recognition method based on Sobel edge extraction and Hough Transform.…”

“…We carried out experiments on our crosswalk dataset. Our method was compared with four crosswalk detection algorithms: Wang's [10], Huang's [11], Michael's [12] and Chen's [13]. In TABLE I, the experimental results show that the proposed method achieves the best among all the tested methods.…”

“…In [24][25][26][27], Lv et al, Zhang et al, Micusik and Pajdla and Hodlmoser et al present self-calibration method which can automatically recover parameters of a static camera based on appearance and motion of persons in a video. Inspired by these works and considered that in a typical monitored scenario, multiple objects such as people move independently on a common ground plane, this paper presents a method for automatically estimating homography matrix induced by the ground plane using video streams from two cameras.…”

“…The estimation of planar homography can also be regarded as calibration problem. According to Hodlmoser et al [27], the task of calibration can mainly be divided into two parts, namely calibration using a known calibration objects and self-calibration. The method using calibration objects has been well studied in past decades.…”
