    We continue with the series about posture recognition with the Microsoft Kinect sensor. This time I will comment the classes responsible of posture normalization of the body in the way commented in the first article, so that we obtain a series of data that constitute a simplified version of the skeleton most appropriate for analysis using pattern recognition techniques.

    With this article I finish the series dedicated to the ThiefWatcher solution, a homemade video surveillance system that is triggered when some intruder enter your home, alerts you by calling to the mobile phone and allows you to obtain at the moment pictures that you can use to help the police quickly identify the thieves and increase the chances of quickly recovering your stolen belongings. In this last article I will explain the App that is used as a remote client of the system.

    In this second article in the series on the ThiefWatcher homemade video surveillance system, I will explain the different protocols that the application uses to interact with its different components, which can be replaced by different new ones allowing a large number of combinations. There is a protocol to communicate with the camera, another to trigger the system, another to alerting the user remotely, and, finally, a protocol to exchange photographs and messages to manage the server from client devices.

    In this series of articles I will do a bit of DIY to build a video surveillance and alarm system against home thefts, using relatively cheap materials and a program that will notify to your mobile phone in case of detecting intruders and allow you to take photographs of them to be able to immediately notify the police and provide them those photos. Rapid identification of thieves can be crucial for you to recover all our possessions quickly.

    In the previous article in this series, I did a summary of the basic components of DirectShow: filters, filter graphs and pins to connect the elements together, and how we can identify them using the GraphEdit tool of the SDK. In this article I will show how to build a "simple" application to capture and playback video using the interfaces provided in DirectShow, a subset of the COM distributed object model from Microsoft.

    Currently there are a lot of video capture devices commercially available; anyone can buy a digital camera or a webcam at a reasonable price. All of these devices can be easily controlled from a program developed by ourselves using Microsoft DirectShow. DirectShow is a set of interfaces that provide a generic API with which you can capture and play audio and video regardless of the brand or model of camera you are using. It also allows recording and playback of files in any format.
