Rotation invarient object recognition
显示 更早的评论
Hi!
I recognize an object via HOG features. But it doesn't detect image's rotationals. Is there any way continuing at my point?
Secondly, in video, i detect with snapshot function. Maybe you know more efficient way..
Edit: get frame via getsnapshot(), than detect via step(dedector, photo)
frame= getsnapshot(handles.vid); bboxes = step(handles.Detector, frame);

I don't understand your first question.
If you're detecting things in video frames, you do need to call getsnapshot(). That in itself doesn't detect anything - it just gets the frame so you can do the detection with an algorithm of your choice.

Perhaps if you want to get a multitude of frames at one time instead of just one frame at a time. You still need to process just one frame at a time though, I think. Though if you're doing something like motion prediction you may have to look at several frames to predict the location in the next frame.
