Displacement filter not mysterious-the substitution principle of the common solution displacement diagram

beginners "vulgar solution" one time. Or to say the replacement principle: (do not say no AH!) ) PS Help in the following points on the replacement map. Note: [] is added by the author. What foreigners translate is hard to understand. 1. The "permutation" filter uses the color values in the displacement chart [in fact, by the specified channel's grayscale value] to change the selection [pixel movement]-0 is the maximum negative change value, 255 is the largest Positive change value, gray value

Summarize the differences between integer and int in Java for detailed parsing

confused mind. So I summed them up and I hope to be helpful to everyone.The code is as follows: public class Main {public static void main (string[] args) {int a = 128; Integer B = 127; Integer C = 127; Integer d = 128; Integer e = 128; Integer f = new Integer ("128"); Integer

code, 2 Magnetic 3 magnetic data, transaction serial number, etc., summed up all can be summed up only about 100 data. Then we can first simple design ISO8583, define 128 fields, all can be considered similar to the above mentioned "account number" and other financial data types, in one order, corresponding to 128 fields in one field. Each data type occupies a fixed length, and this order and length are de

, etc., all the data that can be summarized up to about 100 pieces of data. First, we can simply design iso8583, define 128 fields, and sort all financial data types that can be considered, such as the "Account" mentioned above, in one order, corresponds to one of the 128 fields. Each data type occupies a fixed length, which is defined in advance. This is simple. When you want to send a packet, connect the

The difference and use of ctrl+z, CTRL + C, and ctrl+d in Linux commands __linux

The meaning of ctrl+c,ctrl+d,ctrl+z in Linux Both Ctrl + C and ctrl+z are breaking orders, but their role is different. CTRL + C is the execution of a forced interrupt program. The ctrl+z is to break the task, but the task is not over, he is still in the process he just maintains a pending state.

The reason why there is a lower bound to the source code, the reverse code, and the Supplementary Code

It is found that the negative code is used to calculate and subtract, and the true value of the result is correct. the only problem actually occurs in the special value "0. although we understand that + 0 is the same as-0, 0 is meaningless. in addition, there will be two encoding formats: [0000 0000] original and [1000 0000] original, indicating 0. The occurrence of the complement solves the problem of the zero symbol and two encodings: 1-1 = 1 + (-1) = [0000 0001] original + [10
