Feature detection and matching is a basic problem in computer vision, and Point feature detection and matching are widely used in image stitching and automatic three-dimensional reconstruction. There are generally two ways to detect and match point features: 1 in the image search for those who use the local search method to accurately track the characteristics; 2 independent

This article goes from "TSQ" 1. Hog Features: The directional gradient histogram (histogram of oriented Gradient, HOG) is a feature descriptor used for object detection in computer vision and image processing. It is characterized by calculating and statistic the gradient direction histogram of local region of image. Hog feature combined with SVM classifier has been widely used in image recognition, especially in pedestrian

Back to "flash Basic Theory Class-Catalog" So far, we have learned to interact with objects in their space. Next, look at the interaction between objects. This requires determining when collisions occur between objects, which is what we call Collision detection (collision detection or hit testing). In this chapter I will try to tell you all the relevant knowledge that needs to be mastered. These include t

The new edition of Windows Optimizer was officially launched on September 5, and the updated version is not unusual. The new version is "Standard Edition", and the new free strategy is the long-awaited message of our loyal users of the optimization software. Software is free, and you have to pay attention to the new version of the features and the previous difference. After I first tried, how much got some feeling, at least, the hardware detection has

I. Intrusion Detection System Analysis 1.1 What is an intrusion detection system Intrusion refers to any attempt to endanger the integrity, confidentiality, or availability of computer resources. Intrusion detection, as its name implies, is the discovery of intrusion behaviors. It collects information from several key points in a computer network or system and a

Proceedings of the IEEE Conference on Computer vision and pattern recognition. 2014.The full name of R-CNN is REGION-CNN, which can be said to be the first algorithm to successfully apply deep learning to target detection. The fast r-cnn, Faster r-cnn are all based on R-CNN.Most of the traditional targ

One, web monitoringWeb Scenarios (Web scene) is used to monitor web programs, can monitor the download speed of Web programs, return code and response time, but also support a set of continuous web actions as a whole to monitor.1, the principle of web monitoringWeb monitoring is the monitoring of the HTTP service, simulating the user to visit the site, to compare specific results, such as status code, return string, and other specific data for comparison and monitoring, so as to determine the av

Image preprocessing Several typical noises in digital images are: The Gaussian noise originates from the noise of the electronic circuit and the sensor noise caused by low illumination or high temperature, and the noise of salt and pepper is similar to the particles of pepper and powder which are randomly distributed on the image, mainly by the image cutting or the error caused by the transform domain; In general, the introduction of the additive random noise, mean filter, median filter, Gaussia

Computer popularization, broadband prevalence, now many friends online time is very long, so the security of the system has become "the most important." Fortunately, many security sites now provide online detection services, can be a good help us to detect the existence of their own computer vulnerabilities and security risks, so that timely and effective solutions to these problems. 　　 first, the Internet Assistant Computer physical examination In

The target detection algorithm of the RCNN series previously studied was to extract the candidate regions, then use the classifier to identify the regions and position the candidate regions. The process of this kind of method is complex, there are some shortcomings such as slow speed and difficulty in training. The YOLO algorithm considers the detection problem as a regression problem, uses a single neural

This article describes the hacker intrusion methods for the vulnerabilities in the intrusion detection system. Once the network intrusion detection system is installed, the network intrusion detection system will analyze the online hacker attack events for you, and you can use the counterattack function of this intrusion dete
