Stationmaster, where is the target user group of your website?
Write such a topic, again let everybody laughed at! However, many webmaster friends do not know their site's target user group there. Let's not say much about his target group. And this is precisely a website to determine the quality of the direct factors! So I think it is necessary to remind persona

Recently, Aorato, an Active Directory Monitoring and Protection Expert, targeted at Target data leakage, hackers made a step-by-step report on how they used air-conditioning suppliers to steal data from 70 million customers and 40 million credit and debit cards.
According to a new study by the security company Aorato, after the leakage of personal identifiable information (PII), cr
IET (iSCSI Enterprise Target) is a kernel-implemented iSCSI target, compared to the user-configured target (such as TGT), IET is relatively stable, and also a long history, IO directly through the kernel state, performance is better. This paper is mainly aimed at IET program architecture, from program module, command operation processing flow, initiator and

Target-action: Target-action mode, which runs through iOS development always. But for beginners, it is still confused by this pattern.In fact, the target-action pattern is simple, that is, when an event occurs, call that method in that object. For example: When the button is pressed, the click Method inside the controller is called. "That object" is

In general, compatibility mode can be used, with 32-bit modeler.exe will not be a problem. But to use the 64-bit modeler.exe, and there is the title of the problem, you can refer to this article.

Opencv_createsamples is used to prepare positive sample data and test data for training purposes. Opencv_createsamples can generate positive sample data that can be supported by opencv_haartraining and Opencv_traincascade programs. Its output is a file with the *.vec extension, which stores the image in binary form.
So the OPENCV-cascade classifier training and testing can be divided into the following four steps:

In this paper, a variety of target detection for the problem, combined with the current technical achievements, to achieve a good result.
We obtained solid results on well-known object detection benchmarks:81.8% MAP (mean average precision) on VOC2007 and 82. 5% MAP on VOC2012 (2nd place) while taking only 750ms/image on Intel i7-6700k CPU wi
