This is an introduction to the face detection of technology from the view of the article:
"2016 ACM MM unitbox:an Advanced Object Detection Network".
The code should not be put out, but the implementation is relatively simple. (Interrupt a sentence, the paper said speed can reach 12fps, I'm a little panic, we look at sci
ViBe algorithm: vibe-a powerful technique for background detection and subtraction in video sequences
Judge Net: http://www2.ulg.ac.be/telecom/research/vibe/
Describe:
Vibe is a pixel-level video background modeling or foreground detection algorithm, the effect is better than several well-known algorithms, the hardware memory footprint is also low.
Code:
The algorithm executes the efficiency test program,

PHP detects if URL exists method, PHP detection URL exists
The example in this article describes the method by which PHP detects whether a URL exists. Share to everyone for your reference. Specific as follows:
Copy the Code code as follows: function url_exists ($url) {$hdrs = @get_headers ($url);Return Is_array ($hdrs)? Preg_match ('/^http\\/\\d+\\.\\d+\\s+2\\d\\d\\s+.*$/', $hdrs [0]): false;}
I hope this article is helpful to everyone's PHP prog

How to use the "disk detection function" of Ghost to use the "disk detection function" of GhostBecause I have stored a large amount of data on the e-disk on my computer, the space is too short, and there is a lot of space left on disk C and disk D. Why don't I divide it into parts for the e-disk? Therefore, I used the lossless partition software PartitionMagic (PQ) in Windows to distribute the 1 GB disk and

Corner Point
Feature detection and matching is an important part of the computer Vision application, which needs to find the characteristics of the image to establish the corresponding relationship. Point, which is the special position in the image, is a very common feature, the local feature of the point can also be called "key feature Point" (KeyPoint feature), or "point of interest" (interestpoint), or "Corner" ( Conrner).

Image feature extraction is a concept in computer vision and image processing. It refers to the use of computer to extract image information, determine whether the point of each image belongs to an image feature. This paper mainly discusses how to extract the feature of "Corner point" in image and its related contents. The contents of such as histogram, edge, area and so on are mentioned in the previous article, please check related articles. OpenCv (EMGUCV) realizes a variety of corn
Pedestrian detection plays a vital role in many applications in the computer vision field, such as video surveillance, vehicle driver assistance systems, and human motion capturing systems. image Pedestrian detection methods can be divided into two categories: contour matching and apparent features. the apparent feature is defined as the image feature space (also called the descriptive operator). It can be
