C# motion detection source code: How to achieve tripwire with a USB webcam
Tripwire is a special part of motion detection that can be used to monitor and alert on specific changes. More specifically: tripwire means the detection of intrusion. This code snippet presents how to create a C# software by using prewritten computer vision components (http://www.camera-sdk.com/) allowing you to get notified when your USB webcam triggers an intrusion. For instance, by using this application, you can use your camera to alarm when a people enters into the shop/office, or even to count how many people entered, etc. After the necessary using lines and objects you need to implement the Main method and the necessary functions for connecting to a USB webcamera. The startBt_Click method is used to start the tripwire functionality. Thereafter you can see how to handle the enter and exit events. Nothing could be more simple! :)

Partition a sequence until a predicate is satiated
This function is given a partition predicate and a sequence. Until the predicate returns false, a list will be filled with elements. When it is, both the list and the remainder of the sequence will be returned. Note that this example preserves the laziness of the unchecked sequence elements.
