, according to the above hypothesis, between P0 and Q0 is the real boundary of the object, so there is no need to filter.Standard H. Two sets the threshold α and β to determine the true and false boundary, α represents the boundary threshold between blocks and blocks, and β represents the threshold of the inner boundary of a block. For the difference of pixel points on both sides of the boundary, if the following three conditions are satisfied, it will be judged as the false boundary that needs

Transistor oscillator circuit
Simple, low-cost, transistor oscillator circuit, brief analysis, learning oscillator circuit, in the past found that there are several other products that use this circuit to produce a certain frequency of pulse signal. Interesting. To learn.It can be seen that this circuit is a positive feedback closed loop consisting of two non-gate (inverter) capacitors C1 and C2. The collector output of the Three-Level Tube Q1

This and previous periods are often compared in a report query, such as March sales and February sales. Generally there are absolute and relative value points,
If this period increment = Current period value-the value of the previous period;
Current Period increase = (current period value-previous value)/current period value; relative value

Title One: Print two-fork tree into multiple linesPrint the binary tree from top to bottom by layer, and the same layer node outputs from left to right. Each layer outputs one row.Idea: Initially thought that 2-dimensional vector can be accessed directly, but the test is not, will error, vector in the value can not be directly accessed before, so the problem is to use two queues, the first queue Q1 put a layer, and then put this layer of child nodes a
I. Get the querystring parameter of the URL
Two ways to get the querystring parameter of a URL are as follows:
1.1 Method One: regular match
Gets the parameter
function getquerystring (name) {
var reg = new RegExp (^|) "+ name +" = ([^]*) (|$) in the URL, i) ; Match target parameter
var result = Window.location.search.substr (1). Match (reg);//querystring matching target parameter
if (result!= null) C8/>return decodeuricomponent (result[2]);

and son as two processes. I tried P and V Operations to correctly execute these four processes concurrently.
Analysis: Father and Son processes are mutually restricted. After the father process is executed and put into the drive, the son process can be executed to eat the apple. Therefore, this is a problem of inter-process synchronization.
Solution: semaphore s_platenum; // the disk capacity. The initial value is 1.
Semaphore s_applenum; // Number of apples. The initial value is 0.
