atc4 detection

after scanning the QR Code extraction task, it is necessary to extract the ID number from the ID image and then call the colleague to identify it. the previous connected-domain detection algorithm compares "brute force" because once it detects a large area, all the inner areas of the area will no longer exist. Therefore, in the connected domain detection, the first step is to remove the possible white edge

At present, a website has several versions is very normal, such as PC version, 3G version, mobile version and so on. Depending on the browsing device we need to be directed to a different version. Not only that, we sometimes need to load different CSS depending on the client, so we need to be able to detect the browsing device, so we need to use the "mobile detection" class library. Mobile detection is a P

Theory of odor detection and anti-odor Detection I. Basic knowledge of the stinker 1.1 What is a stinking detector? Sniff is an English form of the stinker. It can be understood as a computer-installed eavesdropping device. It can be used to snoop a large amount of information on the computer's network. A simple explanation: A is a telephone eavesdropping device. A can be used to intercept the communi

Event detection, which detects whether an event exists (available) in a different browser, is also important in the process of writing JavaScript, such as the Mouseenter/mouseleave event is practical, but not all browsers provide standard support, So you need to simulate yourself manually, namely: function addEvent(element, name, handler) { if (name == 'mouseenter' !hasEvent(name, element)) { //通过其他手段模拟mouseenter事件 } //正常的事件注册 }; This article w

from:73439202Problem Introduction:At present, the common target detection algorithm, such as faster R-CNN, has the disadvantage of slow speed. The SSD method proposed in this paper not only improves the speed, but also improves the accuracy.SSD:The core idea of this paper:The main contribution of this paper:1. The SSD target detection method is proposed, which is faster than the fastest YOLO in speed, and c

This series of learning notes is referenced from the OpenCV2.4.10Opencv\sources\samples\cpp\tutorial_code and http://www.opencv.org.cn/opencvdoc/2.3.2/html/genindex.htmlin image processing, it is often necessary to extract an effective edge to the image. This post will cover Laplace edge detection and Sobel edge detection, as well as image remapping. 1.laplace_demo.cpp (Laplace edge

Simple and rough fingertip detection method (fingertips detection) Zouxy09@qq.com Http://blog.csdn.net/zouxy09 In the field of human-computer interaction, if you can better detect your fingertips, it will greatly improve the richness and flexibility of interaction. At present, there are many fingertip detection methods. I have tried two simple methods here. Both

Image processing-by-the-art edge detection and image processing-by-the-art Edge Detection Image processing-edge moderation I. History In 1986, John F. Well developed an edge detection algorithm based on image gradient computing. Detection Algorithm. At the same time, he also made a lot of contributions to the developme

Motion detection (foreground detection) (1) vibe Zouxy09@qq.com Http://blog.csdn.net/zouxy09 Due to the needs of the development of monitoring, there are still a lot of research on foreground detection, and there are also a lot of new methods and ideas. My personal knowledge is summarized as follows: Frame Difference and background subtraction (GMM, codebook, so

Based on the characteristics of hep (histograms of equivalent patterns "1"), which has good texture classification effect, LBP (local binary patterns "2") is the most commonly used feature under the HEP Framework and has a brightness, Rotation and other good invariant properties. In the block-based video smoke detection, it is often used as a feature of texture classification. However, the image of a block is localized. This article mainly proposes th

Do a website of the Android client, the user installed to their mobile phone, if I have a new version how to do? To have a version update feature. Original version detection is best done automatically. But if every time you open the program, you have to first detect a round, is a waste, after all, version update is a small probability of things. Perhaps the process can be opened, judge the time, a single day on the test, the date does not detect, or r

Corner PointFeature 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).There are several specific

Fast Corner detection Fast corner point by E. Professor Rosten suggests that this approach is as fast as its name would be compared to other testing methods. It is worth noting that the theories he has studied are of practical interest and are very fast. Professor Rosten achieved fast corner detection and provided it to the OPENCV, which is quite loving, but the functions in OPENCV and the implementation o

This paper simply introduces the method of the edge detection, and the results of MATLAB are demonstrated. What is the edge. The edge is generally refers to the image in a certain local intensity of the drastic changes in the region. The intensity change generally has two kinds of conditions: 1. Step Change The grayscale change image is shown in the following image (horizontal axis represents spatial variation, vertical axis represents grayscale chan

Four basic technologies can be used to check whether browsers support certain html5 features, from simple to complex order: 1. Check whether the Global Object (window or navigator) has specific attributes.If the browser supports the geographic location API, The Global navigator object will have an attribute named geolocation. Otherwise, the value of this attribute
