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

In the previous article, we introduced several browser feature detection solutions and specific purposes added in jQuery1.4. This article will focus on events and introduce a complete and general event detection solution. In the previous article, we introduced several browser feature detection solutions and specific purposes added in jQuery1.4. This article will

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

DDoS attacks are essentially time-series data, and the data characteristics of t+1 moments are strongly correlated with T-moments, so it is necessary to use HMM or CRF for detection! --and a sentence of the word segmentation algorithm CRF no difference!Note: Traditional DDoS detection is directly based on the IP data sent traffic to identify, through the hardware firewall. Big data scenarios are done for sl

MHA masterha_check_repl detection process, gocheck paper detection Whether the MHA deployment and configuration are OK. We can use the masterha_check_ssh and masterha_check_repl scripts provided by MHA to check whether the MHA deployment and configuration are OK. Masterha_check_repl detection is an important step to ensure successful MHA switching. This article m

Directory Joint probability distribution Normal Anomaly Detection Model Training Model evaluation In real life there are many situations that need to be prevented in advance, for example, before the plane takes off, the aircraft parts are evaluated to see whether the engine and other parts are of normal performance, if there are potential problems (abnormal conditions may occur), it needs to be repaired or replaced in time.So

) that the cube collides with in the current script, we can collision the Collider Component Object (collider) of the colliding game object by the parameters of these three methods. The collider object can then be used to get information about the game object mounted by the collider component.1 // Collision Start 2 void Oncollisionenter (Collision collision) {3 var name = collision.collider.name; 4 5 Debug.Log ("" + name); 6 }In this way, you can get the name of the g

More reliable screen detection methods and reliable screen Detection Methods Not long ago, I made an H5 project and needed some processing when the screen was changed. There is no doubt that you need to useOrientationchangeTo listen for landscape changes. Solution 1: // Listen to orientation changeswindow. addEventListener ("orientationchange", function (event) {// according to the event. orientation | scre

1 Background:The x86 platform has comprehensive user-mode memory detection tools such as valgrind. It can monitor detailed memory information during the running of the program to precisely locate memory problems. However, with the rapid emergence of new platforms, such as the TilePro64 CPU of Tilera, these tools cannot be transplanted in a timely manner. As a result, the new platform lacks the appropriate means to locate memory errors, such as memory

HT for Web visual QuadTree quad-Tree Collision Detection and quadtree Collision Detection A QuadTree tree is a tree-like data structure. Each node has four child nodes, which can recursively split two-dimensional planes into subareas. QuadTree is often used for spatial database indexing, 3D visible area cropping of vertebral bodies, and even image analysis. Today we are introducing the collision

JS implements collision detection method analysis, and js implements Collision Detection This article describes how to implement Collision Detection in JavaScript. We will share this with you for your reference. The details are as follows: A simple Collision Detection example is used to check whether div1 is in conflic

Read a period of time goal detection of the paper, here to write a summary of the article. Do not necessarily understand correctly, if there are problems, please correct me. 1, RCNN RCNN is based on selective search (SS) Searching region proposal (RP), and then on each RP CNN inference, this algorithm is more direct.The framework should also be easy to see and understand.SS extracts approximately 2K of RP for each picture, and then infers the RP. 2, S

Grid loss:detecting occluded FacesECCV2016 The problem of occlusion is to be solved by area chunking. For the occlusion of face detection, it is more difficult to solve this problem from the angle of training data. We solve this problem from the point of view of defining a new loss function. By defining a novel loss layer to block the loss of face counting error, another highlight of this article is real time Our entire network structure diagram 3 Gr

Automatic BUG detection and BUG detection I am a little lazy, and I will never do anything that can be done automatically. Recently I am using ASP.. NET Core writes a project and will accumulate some convenient tool classes or frameworks during the process. If I have time in the future, I plan to write a series of [automatic BUG detection]. This article will be t
