the image with the following convolution core, it is possible. But in practice, this simple method will amplify the noise. Also, it should be noted that all the values of the matrix add up to 0.　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　4. Embossed Embossing FilterThe Emboss filter can give an image a 3D shadow effect. Just subtract the pixels from the other side of the pixel on the center side. At this point, the pixel value may be negative, we use nega

1. Variable naming and usevariable naming rules : A. Variable names can only contain (alphanumeric underscores), and variables cannot start with a number, for example: variable s_1 (correct), variable 1_s (error)B. Variable names cannot contain spaces, you can use underscores to intervalC. Variables cannot be named with keywords and function names, for example: printd. Variable names should be short and identifiable. (see the variable name to know what it might mean)E. Avoid the use of easily co

fan noise, especially when reading the data "click" Sound, more like the late night in the endless wave, enough to make you yell: "Shut up!" 1, isolation is the foundation of earthquake resistance Noise reduction technology is similar, sponge and rubber not only for the fan noise reduction, for hard drive noise reduction, the same effective. For example, some notebook hard drives do not use the public version of the notebook hard drive bracket design, instead, it is wrapped in a special spong

well as no antenna. I used to be in a global enterprise router company, including in the current technology-driven start-up, there are some ingenious methods, because the WiFi environment is complex, each family is not the same, simply increase this sensitivity, sometimes amplified signal can play a hearing aid, and sometimes amplify the noise, causing hearing aids, called Wah. So if the router automatically collects the surrounding WiFi RF environm

method, methods are synchronous, There is no problem with multiple instances of non-static methods.Single-piece (Singleton) mode in 23 design modes if the traditional method is not thread-safe, the following code is a thread-unsafe single-piece mode.Copy CodeThe code is as follows:Package test;Thread-Safe Singleton modeClass Singleton{private static Singleton sample;Private Singleton (){}public static Singleton getinstance (){if (sample = = null){Thread.yield (); To

greatly discounted. There is also a need to mention "so real-time", and so real-time is the search results in the box amplification, in the form of light blog to display relevant content, for such social search to give a strong pillar. Summary: Contrast Goojje, Baidu, and so these three are integrated into the social search, compared to Goojje and Baidu, and so more like an aggregation of goojje and Baidu's essence, and amplify the advantages, to a

frequency band mostly covers the 800~2500mhz, no need to change. Increase 3G in the signal source part of the use of dual-frequency or multiple-frequency coupler to the signal after the road (for the downlink is closed, for the uplink is shunt) sent to the distribution system can be completed. For large buildings, signals in the transmission and distribution process, the signal is low to a certain extent need to use the trunk amplifier to amplify th

Label:The backup of the database is an extremely important thing. If you do not have a backup, you will be crazy if you encounter the following conditions: UPDATE or DELETE whitout where ... Table was DROPPed accidentally ... INNODB was corrupt ... Entire datacenter loses power ... From the data security point of view, the server disk will do Raid,mysql itself also has master-slave, DRBD and other disaster-tolerant mechanism, but they can not completely replace the backup. Disaster tolerance and

development, through the inside some plugins are very useful, reasonable, and very beautiful.The first step is to start by installing the IPA package from inside the app, and then complete the 3 points mentioned above.In general, the installation of 91 assistants, synchronous push such applications require mobile jailbreak, while installing Appsync, so as to use, so the necessary conditions for development is also the same.Upload the demo project add

The following questions were tested in July 2014. There's no guarantee it's going to be different.1. Add app in itunes Connect, title//description/keyword cannot be changed, icon and package name can be changed. The app cannot be deleted after it is added.2. Add a product in In-app purchases, there are no 4 types of options. Reason: "Contracts, tax, and Banking" information on ITunes Connect is not set3, In-app purchases products can not be deleted after the addition.4, IOS6 Simulator can test,

Recently, the legend of the mountain ghost game gave feedback, saying it was a crash. What! What's the case! I tested it with a test machine, and it was impossible to crash! I checked through the Internet for too many reasons. What is the memory shortage? Why is appsync installed after jailbreak (this patch can be used to install the cracked software game, I also accessed a non-existent script (similar to accessing the NIL pointer) and so on. After de

XCode6.0 iOS Certificate-free real machine test method (both MAC and black apple are valid) Currently, iOS programs developed on XCode can only run in Simulator. If you want to test on a real machine, you need an officially authenticated developer account of Apple to buy the developer certificate iDP for $99 a year! As a newbie who just started learning iOS programming, it's really a pain to spend so much money... After some tossing and learning from the posts of various great gods, we finally
