-linear transformation of brightness, as long as the center pixel gray value and the 8 neighborhood pixel gray value of the size of the relationship is not changed , The resulting LBP feature will not change. Note, however, that if the brightness is transformed, the value of the central pixel grayscale is not the same as the gray value of the surrounding pixels, and the LBP feature will change accordingly. For example, the window in Figure 1 has a non-linear change in brightness, and the result
, credit card number, etc. is valid, with ordinary literal-based characters is not enough.
So to use a more liberal way of describing the pattern we want, it's a character cluster. To create a character cluster that represents all vowel characters, place all the vowels in a square bracket:
[Aaeeiioouu]
This pattern matches any vowel character, but can only represent one character. A hyphen can be used to represent a range of characters, such as:
[A-z]//Match all lowercase letters
[A-z]//Match al
be used to indicate the range of a character, for example:
[A-z] // match all lowercase letters
[A-Z] // match all uppercase letters
[A-zA-Z] // match all letters
[0-9] // match all numbers
[0-9 \. \-] // match all numbers, periods, and periods
[\ F \ r \ t \ n] // match all white characters
Similarly, these are only one character, which is very important. If you want to match a string consisting of a lowercase letter and a digit, such as "z2", "t6", or "

In INTERNET programs, regular expressions are usually used to verify user input. After a user submits a FORM, it is not enough to determine whether the entered phone number, address, EMAIL address, and credit card number are valid.
Therefore, we need to use a more free way to describe the mode we want. it is a character cluster. To create a character cluster that represents all vowel characters, put all the vowel characters in a square

[0-9]//Match all the numbers
[0-9\.\-]//Match all numbers, periods and minus signs
[\f\r\t\n]//match all whitespace characters
Similarly, these also represent only one character, which is a very important one. If you want to match a string consisting of a lowercase letter and a single digit, such as "Z2", "T6" or "G7", but not "ab2", "r2d3", or "B52", use this pattern:
^[a-z][0-9]$

Background: In our computer, images are displayed in rgb888 format. Each pixel of the 24-Bit Bitmap stores 32-bit data, that is, rgb888 + Alpha, and Alpha is a translucent padding Byte ...... However, for a true color image, it is difficult for the naked eye to distinguish between 16 bits. Therefore, in some cases, rgb888 can be converted to rgb565 for storage, which reduces the storage capacity, reduces the data size. When the backend is displayed, rgb565 is converted to rgb888 again to achieve
