Fast, accurate Detection of 100,000 Object Classes on a once read recordsThis article is CVPR best paper. This article of cattle, mainly reflected in some key figures, can be classified into 100000 categories, 20,000 times times faster than base line. However, the drawback is that its stand-alone processing of an image of the speed, need 20s, and, 100000 class map is 0.16, looks beautiful, but there are some distance practical distance. This article'

Get System Current TimeWhen debugging, log output, and code optimization, we often need to get the system time. In some performance-demanding code optimization, the accuracy of time is also relatively high. On the internet to find a high-quality code, they have studied, the code is as follows (to meet cross-platform requirements, units accurate to microseconds):#ifdef _WIN32#include #else#include #endif//_WIND32Defining 64-bit shaping#if defined (_WIN

In the process of using cocos2d-x, want to calculate time difference, such as Touchbegin and touchend click Time difference, need to get the current times, this time is usually used to obtain, return unit is time_t on the iOS platform looked down, That is, long, which is the number of seconds starting from January 1, 1970. But this time is not very accurate, can only be accurate to the second. If you wan

parts: exponent and mantissa, such a method of expression will generally lose a certain degree of precision, some floating-point operations will produce a certain error. For example, the binary representation of 2.4 is not exactly 2.4. Instead the nearest binary representation is 2.3999999999999999. The value of a floating-point number is actually computed by a particular mathematical formula. In fact, the Java float can only be used for scientific calculations or engineering calculations, in m

Last time I published a component that writes custom debug information (mainly time) in a record file, but because of the limitations of the CLR, it can only be accurate to about 10 milliseconds. I later referred to an article on the Web: http://blog.joycode.com/lostinet/archive/2005/04/24/49590.aspx (Thanks to the original author here first) gets a time record that can be accurate to about 1 milliseconds b

For Baidu and Google's differentiated optimization, I believe that a lot of stationmaster have their own experience, today, I also hope to share some of their experiences in A5. To come to the point, first of all we have to discuss is Google and Baidu for accurate matching distinction, I am doing English site, my site is the VOA online keyword listening, the VOA official website, then we look, Baidu and Google on the two keywords different ways of tr

relevant words of cooking. Chairman Mao said good: "The countryside surrounds the city, each and all." Do not underestimate the power of long tail words! For, the new station should not, the egg touches the stone, must Shini. Especially in the critical moment to clarify the idea. Strength must be spent on the blade. The weight of your site, slowly rise up, to attack the popular words are relatively easy to point. 　Four, fully understand the industry's light season, to finalize keywords. Each

confidence. After all, everyone knows that the weight of the home page is definitely higher than the column, and the ranking will be good, search for the home page more value, so, use the advantages of the home page to choose with the opponent's column competition, grasp is just. For the opponents of the column page of the key words, we can carefully analysis, column page of the key words is what, generally focused on are more real, no one is willing to do no flow without the search volume. So

accurate scale estimation for robust Visual Tracking I said in the previous blog "Correlation filter Tracking (Mosse)" The principle of correlation filter tracking, but because the article did not provide code, so there is no way to study him in depth, and pure theory seems to be very boring. Martin Danelljan later made improvements to MOSST and added multi-scale tracking to improve the results, which were first tested on this year's vot. Its article

media-but the evaluation of these effects is lagging and inaccurate. With the progress of technology, people found that the results can be real-time, full range of effective feedback and monitoring, and finally can get the precise results of advertising data: How many people clicked, how many people did the interactive to do, how many people have bought behavior ... Wait a minute. So people think that advertising is accurate record, so the precision

10 tips to make your search easy and accurate.Today, users can easily find the information they want through search engines, but it is still difficult to avoid the unsatisfactory results. In fact, users only need to master a few common skills can easily resolve this embarrassment.Here are 10 quick tips to use with Google search, and other search engines support these 10 tips.1. Accurate SearchThe simplest and most effective way to do this is to add do

Article Title: time-based operation functions accurate to microseconds in Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. In Linux, if the time is computed in seconds, I believe everyone has used time and other functions to implement it. But what should I do more accurately? What about milliseconds and micro

[Uidevice currentdevice].batterymonitoringenabled = yes;double Devicelevel = [Uidevice currentDevice].batteryLevel;We usually use the above method to get the current remaining charge. This is also provided by Apple's official documentation.It returns a floating-point value between 0.00-1.00. In addition,-1.00 represents the simulator.Looks like this method is good, also very simple.But careful observation of its return value, we can find. It is with 0.05 homologous. Converted to 100%, that is,

Ogre collision detection, accurate to the object mesh Triangle Surface (19:14:27) Reprinted Tags:Miscellaneous Category: MSN migration The final project of our course is a three-dimensional game of mosquito-sucking blood. Because the volume of mosquitoes is small, and mosquitoes need to fly in 3D scenarios. Therefore, the regular model detection for the box is insufficient. For example, there is a desk lamp in the scenario. From
