Hand Gesture Recognition Using a Kinect Depth Sensor
The goal of this chapter is to develop an app that detects and tracks simple hand gestures in real time, using the output of a depth sensor, such as that of a Microsoft Kinect 3D sensor or an ASUS Xtion sensor. The app will analyze each captured frame to perform the following tasks:
- Hand region segmentation: The user's hand region will be extracted in each frame by analyzing the depth map output of the Kinect sensor, which is done by thresholding, applying some morphological operations, and finding connected components.
- Hand shape analysis: The shape of the segmented hand region will be analyzed by determining contours, convex hull, and convexity defects.
- Hand gesture recognition: The ...
