The latest SVN version of OpenCV contains an (undocumented) implementation of HOG-based pedestrian detection. It even comes with a pre-trained detector and a python wrapper. The basic usage is as follows: from cv import * storage = CreateMemStorage(0) img = LoadImage(file) # or read from camera found = list(HOGDetectMultiScale(img, storage, win_stride=(8,8), padding=(32,32), scale=1.05, group_threshold=2)) So … Read more
The code you used for Kinect 1.0 to obtain a BVH file use the joints information to build bone vectors by reading the Skeleton. public static double[] getBoneVectorOutofJointPosition(BVHBone bvhBone, Skeleton skel) { double[] boneVector = new double[3] { 0, 0, 0 }; double[] boneVectorParent = new double[3] { 0, 0, 0 }; string boneName = … Read more
In 3.0, there’s now an easier way – hook into the new motion events. The main trick is that you need to have some UIView (not UIViewController) that you want as firstResponder to receive the shake event messages. Here’s the code that you can use in any UIView to get shake events: @implementation ShakingView – … Read more
