I. Introduction to the detection of moving targetsMoving object detection in video this piece of the present method is too much. The algorithm of moving target detection according to the relationship between target and camera can be divided into static background motion detection and motion
Image edge information is mainly concentrated in high frequency segment, usually said image sharpening or detection edge, the essence is high-frequency filtering. We know that differential operation is the rate of change of signal, and it has the function of strengthening high frequency component. In the airspace operation, the sharpening of the image is the calculation of the differential. Due to the discrete signal of the digital image, the differen
(1) speed/accuracy trade-offs for modern convolutional object detectors
Its main consideration is three kinds of detectors (Faster RCNN,R-FCN,SSD) as the meta structure, three kinds of CNN Network (vgg,inception,resnet) as feature extractor, change other parameters such as image resolution, proposals quantity, etc. The tradeoff between accuracy rate and speed of target detection system is studied.

Picture detection problems are divided into:
1. Picture Category: Whether it is a car (results only for a single object)
2. Classification and positioning: car, car location (results only for a single object)
3. Target detection: Detection of different objects and positioning (results may contain multiple objects)
Classification and posi
As a result of the course work, summary of the recent domestic literature on pedestrian detection, although it was written in 2014 and 2013, but the content of the review is still a classic thing. As a tour review.Xu Teng, Huang, Tian Yong. Survey of pedestrian detection technology in vehicle vision system [J]. Chinese Journal of Image Graphics, 2013,18 (4): 359-367.In this paper, the most important two lin

Summarization of algorithm for moving target detection and tracking process
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 cause
First, we look at the new progress of target detection from CVPR2016. The 2016 CVPR conference target detection method is mainly based on convolution neural network framework, Representative work has resnet (in faster r-cnn ResNet replacement Vgg), YOLO (regression detection framework), locnet (more accurate positioning), Hypernet (High level information of neura

Prior to the emergence of deep learning, the traditional target detection method is probably divided into regional selection (sliding window), feature extraction (SIFT, hog, etc.), classifier (SVM, adaboost, etc.) three parts, the main problems have two aspects: on the one hand, sliding window selection strategy is not targeted, time complexity, window redundancy On the other hand, the

In the DirectX SDK, the correlation function for collision detection is in xnacollision.h. Now, however, the previously implemented correlation functions have been transferred to the Windows SDK DirectXCollision.h and are in namespace DirectX. This consists mainly of four bounding boxes (bounding Volumes), and is implemented in the form of classes:
Boundingsphere class-Surround ball (bounding Box)
BoundingBox Class--axis aligned bou
1. What is status detection?Each network connection includes the following information: Source Address, Destination Address, source port, and destination port, called socket pairs, protocol type, connection status (TCP protocol), and timeout time. The firewall calls this information stateful. A firewall that can detect each connection status is called a status packet filtering firewall. In addition to completing the packet filtering of the simple pack
1. Hog features:
Histogram of Oriented Gradient (hog) is a feature description used for Object Detection in computer vision and image processing. It forms a feature by calculating and counting the gradient direction histogram of the Partial Area of the image. Hog feature combined with SVM classifier has been widely used in image recognition, especially in pedestrian detection. It should be noted that the ho

LAN networks are easy to use, but it is not easy to manage. Different Internet access needs alone make the network administrator busy, not to mention frequent network faults. This is not the case. Intermittent failures on the Internet are very common. The factors that

Although recent depth object detection methods such as: Fast/faster RCNN
In the previous article, "OpenCV feature2d learning--surf and SIFT operators to achieve feature point detection", the use of SIFT and surf operators for feature point detection, here is trying to use fast operator for feature point detection.Fast's full name is:Features from Accelerated Segment test, the main feature values are fast, much faster than other known feature point
Snort is a multi-platform, real-time traffic analysis intrusion detection system. Snort is a packet sniffer Based on libpcap and can be used as a lightweight network intrusion detection system.
Snort has three working modes:1. snifferSniffing mode: reads data packets from the network and displays them as continuous streams on the terminal.2. Data Packet RecorderData Packet RECORDER: records data packets to
Apt attacks are advanced attacks that have emerged in recent years and are characterized by hard detection, long duration, and clear attack targets. Traditional intrusion detection and defense methods based on attack characteristics have poor results in detecting and defending against apt. Therefore, various security vendors are studying new methods and proposing a variety of solutions. At this year's rsa s
