2014-05-22 08:16:05 -0600 | commented answer | cvWaitKey is not generating key codes for naviagation keys this is work for me. (dec)82 corresponds 'R'. http://en.wikipedia.org/wiki/ASCII May be that some locale issue? (which depend from system, too. Win, linux, etc.) |
2014-05-21 09:01:01 -0600 | commented answer | cvWaitKey is not generating key codes for naviagation keys That value depends from architecture of your system. For example, for me "up_key" equal (int) 2490368. |

So I can't determine _direction_ only by hog detector out_rectangles, because there are several pedectrians in one frame.

2014-01-17 08:56:49 -0600 | commented answer | DefaultPeopleDetector: true pedestrian height sorry, "true height" -- it is man's height at the picture by pixels. I forgot about IRL world and what "true height" is it by meters :-) I notice, then I increase HeightPedestrian from real 250 pixels (measured by A Ruler For Windows http://www.arulerforwindows.com/ from my video, which on screen thanks to cv::imshow) to 350 -- quality of detector increase. So I propose that in resizeRatio term actually not 128.0, but lower. Are you sure what all pedestrians were resized towards a 64x128 window from top to heel, without sky and ground on top and bottom of image? |
2014-01-17 08:28:44 -0600 | answered a question | how to detect people from the back Put your camera at level of heads (when people sit), consider part of images (video) above heads, and then use algorithm, base on frame difference. When every one is sit -- where is no change in area above heads, when someone stand up -- he create big difference, that difference is your classifier (everyone sit / someone stand up) |
2014-01-17 08:12:29 -0600 | edited question | DefaultPeopleDetector: true pedestrian height
Performance is important, and I approximately know height of my pedestrians -- so I using Firstly I resize my target area to detector resolution (coefficient of resizing equal to ratio between "detector height pedectrian" and "my data height pedectrian"), and then perform detect function. code: |
