This paper shows the importance and benefit of coupling cloud computing with mobile especially due to power limitations that mobile devices exhibit. Moreover, the work done shows that mobile computing can be applied for educational purposes, where a tool for students termed Mobi4Ed is presented. This educational tool aims at exploiting the concept of cloud computing in the context of image and video...
The paper proposed a fast face detection algorithm which integrates differential algorithm and mosaic rules for videos. The comprehensive algorithm with temporal difference and background difference was used for acquiring and tracking the moving objects, which can accurately locate the target region. In the region, the gray rules based on mosaic image were used for detecting face, in which the integral...
This paper presents a rapid solution for face detection. It is based on AdaBoost (Adaptive Boosting) learning algorithm and abstracts faces' Haar-like features to train a classifier. At last through the OpenCV, develop a program that can detect people's face from the video of PC camera.
This paper aims to analyze the direction of the passengers' movement according to the video shot in the public locations. The analysis result will help related departments to manage the transport situation and make a decision when confronting emergency. First, the paper realizes the detection of people's head based on Haar feature and Adaboost algorithm through OpenCV, Second, the paper investigates...
Lecture recording plays an important role in online learning and distance education. Most of they are recorded by a cameraman or a static camera. In this paper, we propose an automatic lecture recording system. A Pan-Tilt-Zoom (PTZ) camera is shooting as it operated by a cameraman. Three parts are developed in this system. The first one is preprocessing for detecting the position of the lecturer and...
As the principal place for currency flow nowadays, the banking system plays a special role in society and its security has always been a focus. The current bank branches' security systems usually use video surveillance system, which is basically used to provide evidence after incidents, and it can not do real-time warning. With the rapid development of computer vision, video and intelligent recognition,...
To realize the real-time tracking of the shoot point from light pen, we choose Camshift tracking algorithm, but it is difficult to track the point with dynamic and complicated background and in case that there is similar color with the shoot point from light pen. So, an improved method is proposed. Firstly, a red filter which weakens the effect of background, and makes the object prominent is introduced...
