some time ago, I saw MacLean Liu share a good article on Exadata I/O performance calibration: Calibrate Test Exadata IO, this article basically covers the exadata I/O performance calibration method. Just recently someone has asked me this question, so I will try to make some additions to the fish, there is duplication of places please ignore it.
If I/O performance cal
Print offset calibration only for express single printers, different brands and models of printers are likely to print offset, and most of the printer does not provide the hardware calibration function, so the Silver Fox provides a printing offset calibration function, to achieve a more accurate software migration.

http://www.vision.caltech.edu/bouguetj/calib_doc/This URL is a tutorialProblem one : No image in the This directory in either RAS, BMP, TIF, PGM, ppm or JPG format. Change directory and try again.Cause: The path is not correct and there is no picture at the current path.Try: Try the set path to the working directory under MATLAB, but it doesn't work. The Matlab2014a\bin is displayed with the PWD command. Workaround: Add a command CD to the working directory "image" Matlab Image
Method:1. Verify in the action class in the Execute () method.Pros: The action class does not have to inherit classes from the framework.Cons: (1) when there are multiple checksums, the code repeats, violating high cohesion and low coupling.2. Rewrite the Validate () method in the framework Actionsupport class.Pros: Contains the This.addfielderror () method, and once invoked, the action ends.Cons: (1) need to inherit the Actionsupport class (intrusive) in the framework.(2) Disadvantage of Method
2^j range is 0 ~ 2^ (r-1). So the transformation then goes back to the previous n situation. The difference is that the range of n is 2^r But in fact, the essence has not changed. We can still find a Q that makes 2^q So, as you can see, in this way, subtracting a power of 2 from N continuously, you can get one and only one sum, so that it and Ni.e. 2^i + 2^j + ... + 2^r= nMathematically, this is called Mathematical induction:)Above we prove that for any one bit n, there is only one and the same

This method is a method between the traditional calibration method and the self-calibration method, although the trad
Win7 method for calibrating display colors using the self-display color calibration tool
Monitor is an important part of the computer, color quality directly affects the user's visual enjoyment, so many users like to use Third-party software to calibrate the display color, make it more beautiful. If you are a Win7 system user, then the small series can tell you, Win7 itself with the display color calibration
Camera CalibrationCamera calibration: Simply speaking, it is the process of acquiring camera parameters. Parameters such as: in-camera parameter matrix, projection matrix, rotation matrix and pan-shift matrix, etc.
What is camera parameters?
Simply put, the real world of people, objects, shot into a picture (two-dimensional). The three-dimensional coordinates of a person or thing in the world, and the relationship between two-dimensional

The colors you see on the screen will depend on your display, graphics settings, lighting, and so on, and most people use the same default Windows color profile. Now WINDOWS7 provides a display Color Calibration wizard to help you set your brightness, contrast, and color settings correctly.
This feature allows you to adjust the gamma, brightness, contrast, and color balance to ensure that the screen colors are displayed correctly.
This feature can b

This example shows you a technique for calibrating a sensor: Read the sensor value for 5 seconds at startup, then look for its maximum and minimum value. The maximum and minimum values after calibration will be useful in the map function.

In the control panel, the path is "appearance and personalization" and there is "color calibration" in the display subitem ";Click "color calibration". The color calibration page is displayed;After clicking "next", some basic introductions and requirements for color calibration
Why adjust and correct the camera?
Depending on the camera you use, there will be differences such as the focal distance and lens skew. The characteristic values (camera parameters) of cameras like this will affect the calculation process of the 3D positions marked by the image, this affects the placement of 3D objects after they are generated. In order to get the correct measurement results, you must adjust and correct the camera parameters before the experiment.
