Transferred from: http://blog.csdn.net/likezhaobin/article/details/6892176The edge of image refers to the part where the brightness of the image is changed significantly, and the gray section of the region can be regarded as a step, which changes from one gray value to another in a very small buffer area to a gray scale with a large difference. The edge of the image is focused on the most information of the image, the determination and extraction of image edge is very important for the whole ima

ObjectiveOriginally wanted to follow the convention to a overview, the result saw a very good and detailed introduction, so copy over, their own in front of the general summary of the paper, the details do not repeat, citing the article is very detailed.Paper Overview Citation articleThe following are from: http://lowrank.science/SNIP/This log records some notes on the following article CVPR 2018 Oral.

But I don't really like this way, I'm using a classic algorithm: SAT a fast detection of irregular convex polygon collision of the algorithm to give two convex polygons, if we can find an axis, so that the two objects on this axis projection does not

"Debug" Linux ultra-strong memory detection Tool ValgrindContent Introduction What is Valgrind? Use of Valgrind Valgrind Detailed Tutorials 1. What is Valgrind?Valgrind is a set of Linux, open source code (GPLV2) A collection of simulation debugging tools. The valgrind consists of the kernel and other kernel-based debugging tools.The kernel is similar to a framework (framework) that simulates a CPU environment and provides servic

Recently encountered a project, front end with Apache HTTTPD for publishing (80 port), through the dual-machine load balancer forwarding to the back end of two tomcat processing (8081 and 8082 ports), now need to monitor the situation of these three ports, once down the need to be able to immediately alarm processing. Batch system monitoring is a good use of nagios software to achieve, such a small project to install a Nagios software, a bit cumbersome. On the Internet to check some information,

Due to the recent use of ICF,DPM and other new pedestrian detection algorithm, found the Open Source Library CCV http://libccv.org/tutorial/, but the code is under the Linux platform, the company machine does not allow itself to install dual systems, the use of visual box+ Ubuntu for implementation, the specific implementation steps are as follows:First, install the Visualbox+ubuntu1 Downloads Visualbox https://www.virtualbox.org/2 download ubuntu htt

export the check information, refer to the following directives:cppcheck --enable=all 1 –enable= has a number of parameter options, detailed reference to the Cppckeck parameter description, and the recommendation to use all according to the Cppcheck help, which is useful when scanning all files for the entire project, as it can check for unused functions.4. Use aloneCppcheck provides the operation interface, such as, click on the left C + + button, select the directory, you can a

So far, the need for memory leak detection has been largely met by the method of wrap malloc, new function overloading, and calculation of pointer memory size.If a memory leak is found, then find out where the memory leaks are and fix it.Boundless code, how to find? It would be nice if we could find the place to apply it based on the memory that was not released.We are going to do it today. To identify the applicant's information based on the memory

Typically, there are two ways to detect network connectivity for Linux systems:1. Through "ping command + Destination IP" or "Ping + target IP domain"Note IP network detection for IPV6 address need to try ping6, while ping6 can not use parameter hops, because the IP6 source has abandoned the route, see the following English explanation:Synopsisping [-AABBDDFHLNOQRRUVV] [-C Count] [-f Flowlabel] [-I interval] [-I interface] [-l preload] [-m mark] [-M P

January 27, 2015 The gethostbyname function of the Linux GNU glibc standard library burst into a buffer overflow vulnerability, with the vulnerability number cve-2015-0235. The hacker can realize the remote code execution through the GetHostByName series function, obtains the server control and the Shell permission, this vulnerability triggers the way many, the influence scope is large, has confirmed the successful utilization software and the system: GLIBC 2.2 to 2.17 (contains 2.2 and 2.17 ver

Memwatch Brief IntroductionAmong the three types of detection tools, the simplest is the memwatch, which, like Dmalloc, detects memory that is not released, multiple releases of the same memory, access errors, and improper use of unallocated memory areas. Please go to http://www.linkdata.se/sourcecode.html to download the latest version number of Memwatch.Installation and use of MemwatchFortunately, Memwatch does not need to be installed at all, becau
