Method to Remove Handwritten Texts Using Smart Phone

To remove handwritten texts from an image of a document taken by smart phone,an intelligent removal method was proposed that combines dewarping and Fully Convolutional Network with Atrous Convolutional and Atrous Spatial Pyramid Pooling(FCN-AC-ASPP).For a picture taken by a smart phone,firstly,the image is transformed into a regular image by the dewarping algorithm.Secondly,the FCN-AC-ASPP is used to classify printed texts and handwritten texts.Lastly,handwritten texts can be removed by a simple algorithm.Experiments show that the classification accuracy of the FCN-AC-ASPP is better than FCN,DeeplabV3+,FCN-AC.For handwritten texts removal effect,the method of combining dewarping and FCN-AC-ASPP is superior to FCN-AC-ASP alone.

Roadroid： Continuous Road Condition Monitoring with Smart Phones

Road condition is an important variable to measure in order to decrease road and vehicle operating/maintenance costs, but also to increase ride comfort and traffic safety. By using the built-in vibration sensor in smart phones, it is possible to collect road roughness data which can be an indicator of road condition up to a level of Class 2 or 3 in a simple and cost efficient way. Since data collection therefore is possible to be done more frequently, one can better monitor roughness changes over time. The continuous data collection can also give early warnings of changes and damage, enable new ways to work in the operational road maintenance management, and can serve as a guide for more accurate surveys for strategic asset management and pavement planning. Collected measurement data are wirelessly transferred by the operator when needed via a web service to an internet mapping server with spatial filtering functions. The measured data can be aggregated in preferred sections, as well as exported to other GlS （geographical information systems） or road management systems. Our conclusion is that measuring roads with smart phones can provide an efficient, scalable, and cost-effective way for road organizations to deliver road condition data.

An ECG Monitoring and Alarming System Based On Android Smart Phone

ECG monitoring in daily life is an important means of treating heart disease. To make it easier for the medical to monitor the ECG of their patients outside the hospital, we designed and developed an ECG monitoring and alarming system based on Android smart phone. In our system, an ECG device collects the ECG signal and transmits it to an Android phone. The Android phone detects alarms which come from the ECG devices. When alarms occur, Android phone will capture the ECG images and the details about the alarms, and sends them to the cloud Alarm Server (AS). Once received, AS push the messages to doctors’ phone, so the doctors could see the ECG images and alarm details on their mobile phone. In our system, high resolution ECG pictures are transmitted to doctors’ phone in a user-friendly way, which can help doctors keep track of their patient’s condition easily.

VREG: A Virtual Reality Educational Game with Arabic Content Using Android Smart Phone

In the last few decades, technology found its way from being a wild sci-fi dream, only seen in movies, to being an important element of all aspects of life. The technological industry bloomed quite rapidly where the technological solutions have made any process you can think of easier, faster and more efficient. Educational methodologies started off simple, having a teacher using simply his/her words and some writing along with it. With technology entering the field of education, teaching methods were enhanced and the quality of its outcomes was improved. However, sadly in Arab countries that was not the story. In other words, the use of new education technologies is still limited to basic and simple tasks. In fact, to add to the agony, most of the programs used are poorly implemented and rarely applied. Interestingly, as many studies confirm and from the simple observation of kids playing, it is found that most children are very attracted to new technologies and their applications. Those interests not only changed what a normal childhood would look like, but also introduced a multi-billion industry of electronic games. Virtual Reality (VR) games were introduced a few years back starting a gaming revolution, allowing gamers to enter the world of their dreams. Similar to most technologies, VR started to become more affordable with time. Multiple companies have competed to give us amazing VR products such as Samsung Gear. In this manuscript, we present a Virtual Reality Educational Game (VREG), which is an interactive 3D game with Arabic content that targets the students between age 4 and 8 and can be played on a smart phone. VREG includes multiple games that cover the different concepts of Arabic and English languages alongside math, aiming to help the student to learn through playing. In order to make sure that our game reaches wanted education standards, we put it to the test in two private schools;the feedback was very positive from both teachers and students where the majority of users enjoyed their experiments in VR games.

Commwarrior worm propagation model for smart phone networks

Commwarrior worm is capable of spreading through both Bluetooth and multimedia messaging service （MMS） in smart phone networks. According to the propagation characteristics of Bluetooth and MMS, we built the susceptibleexposed-infected-recovered-dormancy （SEIRD） model for the Bluetooth and MMS hybrid spread mode and performed the stability analysis. The simulation results show good correlation with our theoretical analysis and demonstrate the effectiveness of this dynamic propagation model. On the basis of the SEIRD model, we further discuss at length the influence of the propagation parameters such as user gather density in groups, moving velocity of smart phone, the time for worm to replicate itself, and other interrelated parameters on the propagation of the virus. On the basis of these analytical and simulation results, some feasible control strategies will be proposed to restrain the spread of mobile worm such as commwarrior on smart phone network.
