Intellectual big Surf (riddle) Title DescriptionXiao Wei enrolled in CCTV's intellectual big surfing program. The challenge attracted a lot of contestants, the host to honor everyone's courage, first reward each contestant M yuan. Don't be too happy first! Because the money is not necessarily yours?! Then the host announced the rules of the game:First of all, the game time is divided into N-period (n≤500), it gives a lot of small games, each small

Bloggers in the spirit of learning to install a CENTOS7 on the virtual machine to knock the command line. At first, we met with strong resistance ...Ifconfig vim is useless.

The surf algorithm is an accelerated version of The sift algorithm. The surf algorithm of opencv basically achieves real-time processing by matching objects in two images under moderate conditions, the quick foundation is actually only one-the integral image Haar derivation. For other differences, refer to another article on Sift in this blog. Both scientific research and application hope that the same scen

To understand surf, first understand the relationship between the integral image and the Hessian matrix.In sift, the dog space is first generated, and then the Hessian matrix is calculated in the dog space. In surf, the process of generating a scale space is implicit. For the same integral image, the Hessian matrix of each point on the image is directly calculated using an ever-increasing scale (the theoret

Using C ++ to rewrite the opencv surf algorithm example (find_obj)Creation After opencv 2.0, a large number of standard template class STL were used, and the image structure was unified to mat, and the SURF class was provided. The find_obj.cpp contained in opencv2.2 was actually mainly written in C structure, I have never found the corresponding C ++ example.So I took the time to rewrite it. For the sake of

At the same time, if you are the telephone line access to the home broadband, "Modem" is also an essential device, commonly known as "cat",
