1.3.1 HSB color space model and its branches The principle of first contact with the HSB mode starts from the following address.Http://zh.wikipedia.org/wiki/HSL%E5%92%8CHSV%E8%89%B2%E5%BD%A9%E7%A9%BA%E9%97%B4 Figure 1.21 shows a color space copied from the previous article. It can be seen that HSB can be divided into HSL and HSV modes in the industry at least. They all use three-dimensional coordinate systems to describe the distribution of color valu

of f (x) is found, the value of Y is Argmax (f (x) can be used as the so-called "basis" I think that's why the literal translation is called "max (min) argument ". I hope I do not understand it... The Chinese wiki does not have this. It seems that I do not know the Chinese. At least it is correct to apply it to folie ~ 2. What does Arg min mean? The most common understanding: indicates the variable value when the target function is set

: With A1, A2, A3, A4, A5 Five nodes, A1 has an operation to change a value to X, A1 to all knot dots requests, where there is no exception, the timing diagram is as follows:Example 2: An exception, there are A1, A3, A5 three nodes, A1 and A5 at the same time the request to change the value, but the A5 request a long time, after the A1 proposal all over, A3 only received, A3 how to do? The timing diagram is as follows:Example 3: An exception, there ar

object-oriented language can be implemented, but they are only after you have made the object-oriented design, you can write a little more comfortable-but, if a project does not need to make an object-oriented design, Some object-oriented languages can make you very difficult.write programs in object-oriented languages, and a program is designed to be object-oriented, and the two are not the same thing that eight Poles can't fight.。 The Linux kernel written in plain C is actually more object-or

other directly between the two.The key point is how to "shake hands", so long as we have done the handshake, then Webscoket technology can be used.The previous said WebSocket and HTTP have the intersection, or can say WebSocket with the help of HTTP is reflected here, you can see the red dots in the figure, respectively, is the WebSocket request head and the response head, one back, the handshake is completed, Real-time connectivity is also built up!

Original link: http://developer.nokia.com/community/wiki/Image_editing_techniques_and_algorithms_using_QtThis article mainly describes how to use QT at pixel level to manipulate the image, and achieve some image effects, these effects are: grayscale, blur, sharpen, add frame, metal texture, change the image saturation, brightness and white balance.IntroducedIn this article, we will discuss some techniques and algorithms for modifying images in Qt, bef

the conversion formula "sp*ppi/160 = px" of SP and px. We cannot work out all the cases, so we only compute the pixel heights corresponding to the preferred PPI. The second step: the calculated pixel height and Conversion formula "SP * ppi/160 = px" At the same time output to the front end, so that after the PPI, the front-end can be automatically calculated. In addition, the front-end code to define the height of the font is also PX, so the designer to the front-end output to PX calculated si

PPI: pixel density, pixels per inch (1inch=2.54cm), which is the number of pixels per screen. Pixel density =√{(length pixels ^2+ width pixels ^2)}/screen size.Dpi:dots per inch, point in dots, refers to the printing accuracy in the printing industry. In the official Android development Guide, the meaning of the PPI is the same as that of pixels per inch.Resolution: Refers to the number of pixels in the horizontal and vertical direction of the phone s

Source: From the ancient yueju blog We have introduced the features and structure of ROS. Next we will begin to prepare for the strong Ros. On the Wiki on the ROS official website, the tutorials for new users are very detailed. It is best to clarify all the tutorials for new users. This is the most basic thing for later development. Despite this, Ros is still difficult for beginners to get started. Here, I will summarize my learning history and serve

Imagine creating a library of wikis. Wiki sites contain content that users can create, delete, and modify interactively. Many wikis feature a simple, text-based markup language for creating content. Typically, these markup languages provide only a subset of the functionality available in HTML, but there is a simpler, clearer source format. For example, text that surrounds the asterisk is formatted as bold, and the underlined text is formatted as an un
