the range of [0, 255]. Because XYZ has to be normalized to x1y1z1, we can actually make this change in the transformation matrix m, multiplying each row by a factor so that the sum of each number of rows is 1: [M1] = [0.4339, 0.3762 0.1899; 0.2126, 0.7152, 0.0722; 0.0177, 0.1095, 0.8728] As a result, we get a semi-finished product: L = Y1 = 0.2126 * R + 0.7152 * G + 0.0722 * B A = Fa * (x1-y1) + Da b = Fb * (Y1-Z1) + Db The FX is the coefficient used to adjust the range, and the DX is a pos

The map method calls the callback function once in order for each element in the original array. The returned values after each callback operation are combined to form a new array. The callback function is called only on indexes with values. indexes that have never been assigned or deleted using delete are not called. In our daily development, operations and conversion of arrays are common operations. Let's look at an example: The Code is as follows: Var desColors = [],SrcColors = [{R: 255, g

define a "digital oscillator. Every time an osc () is called, it returns a scheduled sample generated from the Xuan-Bo. Using sound sampling and sound frequency specifications, it is sufficient to generate audio in the WAVE format. The-1 to + 1 in the produced positive and Xuan waves are moved and adjusted, so that the byte data of the sound can be expressed as 0 to 255, and 128 represents the zero amplitude. At the same time, we need to consider ano

In our normal work, we sometimes need to operate on a file, such as adding ##in front of each line of a file. In shell, this requirement is very simple, you can use the sed single line to solve the problem. Let's take a look at a file: [Root @ host-192-168-209-128 py-sed] # cat a.txt This is a text This is use for python This is also user for sed This is a end test file [Root @ host-192-168-209-128

Common Character sets include ASCII, GB2312, GBK, UTF-8, Unicode First, you must know ASCII code: One byte is used to identify 0-9 numbers, uppercase and lowercase letters, and some punctuation and invisible characters. 1 byte, 8 bits, can have 256 combinations. The standard ASCII encoding only uses the last 7 bits (128 combinations) of one byte, and the highest bits are used for parity. The range is 0000 0000-0111 1111, that is, 0-127. Because ASCI

password is obtained. Step 5What we need to do is modify the password of the original account in the system. First, we register a user in DNN. Assume that the account and password we have registered are both testmd5. Then, we can go to the database to check that there is a password "3a25306bb46a03d6" account. This is the 16-bit md5 password of the new testmd5 password. We can use the following script to change the host password so that the password becomes testmd5.view plaincopy to clipboardpri

. Binary representation of positive and negative numbersWe know how to convert a decimal number into a binary number, but how is it expressed in a computer? Here we will talk about the difference between memory representation during the program running and actual hard disk storage. what files are stored on the hard disk are basically all processed as characters. Each number corresponds to a character number. Now unicode is popular, and each character is represented by the corresponding number i

The map method invokes the callback function sequentially for each element in the original array. Callback the return value after each execution is combined to form a new array.
