OPENCV Learning---moving target (foreground) detection
1. Frame Difference method
Principle: The video sequence uses pixel-based time difference between two frames or three frames, and the motion region of the image is extracted by the closed-value.
Advantages: The algorithm is simple, the computational amount is small, the training background is not necessary, and the light is not sensitive to the slow transformation.

Copy constructors and copy assignment operatorsstarting with C + + 11, the language supports two types of allocations: copying assignments and moving assignments. In this article, "assignment" means copying an assignment unless there are other explicit declarations. Assignment operations and initialization operations cause the object to be copied.Assignment: When you assign the value of one object to another object, the first object is copied to the s
The application background of infrared video moving target detection: the usual video target detection, often is the visible light target detection, this detection and tracking technology has been very mature, but there is an unavoidable flaw, it is not in the light of the situation to carry out effective detection, in the night without light can not be detected at all. and infrared detection can make up for such deficiencies. Infrared video is imaged

1. Identify the activity of a moving object using a shadow object
In order to interact with the scenario more realistically and provide good visual and operable feedback, computation based on various situations is essential.
For example, when the height of an area changes in vain, by default, some raised polygon will block the moving direction of the moving obje

I. Introduction to the detection of moving targetsMoving object detection in video this piece of the present method is too much. The algorithm of moving target detection according to the relationship between target and camera can be divided into static background motion detection and motion detection under dynamic background. Start by simply discussing the background type from the video.The target detection

Introduction to various target detection methods (lazy people can skip directly)
Target detection is an old topic, and in many algorithms there is a shadow of it. Target detection has two things to do: detect if there are any targets in the current picture. If there is, where. According to the prior knowledge and background movement to divide, the targe
Introduction to the conversion and Division Algorithms
In number theory, the moving phase division (generally referred to as Euclidean algorithm or Euclid's algorithm internationally, that is, the Euclidean Algorithm) is a unit (for example: integer. An important feature of this algorithm is that it does not need to break down the formula to obtain the maximum common number. The transfer and division method is a common algorithm used in computer progr
Now it is time to resolve the issue left in chapter 8, when there are no obstructions between the distinction and original place, the sprite still use a * algorithm to find path, rather than moving between these 2 point directly, as follows:
So we need to modify moving mechanic. when we click on the map, the sprite 'Action is default to move in straight path. and we create a new thread to detect if th
