You also need to take into account the problem of one step in the traversal process. This template slides 10 pixels at a time, so a total of 9 slides are required. In addition to the first No. 0 time, the total in the horizontal and vertical direction respectively have 10 such templates, a total of 100 templates. To calculate these 100 templates, the Haar feature on the whole picture can be calculated. And if our step size is set to 5*
