Handheld Camera

Handheld mobile devices are a dime a dozen in the industry, thanks to rapid technological advancements. However, none of the algorithms currently available on the market can remove reflections in a hand-held camera system in real time. Our Algorithm is intended to mitigate this loop as it is designed especially for smart phones, we’re taking two photos of the same goal here. One shot will be taken with the flashlight turned OFF, while the other will be taken with the flash turned ON. After that, we’ll perform a simple pre-processing phase called aligning the image, which involves extracting features. We will eventually get the final desired picture of good quality after all the planned operations are completed.

Abstract— There is a remarkable growing interest in utilizing mobile communications to enhance the interactions between different partners in educational institutions, particularly in schools. However, how communicating with parents via applications while aren't actively running is quite a challenging demand. On the other hand, the addressed success of the Android supporting features provided a good candidate to support applications with real time information. Moreover the Android platforms supports efficiently customizable notifications, which allow applications based on Google Cloud Messaging (GCM) to specify the pushed events. In this paper, we look at different push messaging alternatives available for Android. Push messaging provides an important aspect of server to device communication, and we specifically focus on the integration of cloud computing with mobile devices through the use of push-based technologies. The paper presents a proposed notification system; ToParent, that actively provide alerts and messaging between parents and schools. Also, we investigate the performance of two relevant push technologies for the Android devices .The proposed system was implemented using Eclipse. The system has been tested and validated. Evaluation have proven that the proposed ToParent enabled better efficiency, and good overall satisfaction of both parties; parents and school administrations.

The proliferation of mobile devices such as smart phones and tablets with powerful audio-video features, image and video editing apps, and powerful sharing tools has served as catalyst for the deployment of mobile devices in both journalism education and practice around the world. A survey of mass communication students has revealed strong passion for mobile journalism as a professional career path. Respondents noted that mobile devices loaded with relevant apps carry an advantage over traditional cameras in terms of enabling video editing, mobility, and sharing when compared to standard cameras. The writers argue that mobile devices hold a huge promise for both journalism teaching and practice because of their ubiquity, mobility, multifunctionality, networkability, and professional output. On the other hand, the writers see some challenges in this area when it comes to public perceptions of professional journalism as based on ‘professionally-oriented' rather than ‘consumer-oriented' production gear and slow software enhancement by both device makers and app developers.

M-learning or mobile learning is defined as learning through mobile apps, social interactions and online educational hubs via Internet or network using personal mobile devices such as tablets and smart phones. However, in such open environment examination security is most challenging task as students can exchange mobile devices or also can exchange information through network during examination. This paper aims to design secure examination management system for m- learning and provide appropriate mechanism for anti- impersonation to ensure examination security. The users are authenticated through OTP. To prevent students from exchanging mobile devices during examination, system re-authenticates students automatically through face recognition at random time without interrupting the test. The system also provides external click management i.e. prevent students from accessing online sites and already downloaded files during examination.

We present a real-time rendering technique for photometric polygonal lights. Our method uses a numerical integration technique based on a triangulation to calculate noise-free diffuse shading. We include a dynamic point in the triangulation that provides a continuous near-field illumination resembling the shape of the light emitter and its characteristics. We evaluate the accuracy of our approach with a diverse selection of photometric measurement data sets in a comprehensive benchmark framework. Furthermore, we provide an extension for specular reflection on surfaces with arbitrary roughness that facilitates the use of existing real-time shading techniques. Our technique is easy to integrate into real-time rendering systems and extends the range of possible applications with photometric area lights.

Smart grid endpoints need to use two environments within a processing system (PS), one with a Linux-type operating system (OS) using the Arm Cortex-A53 cores for management tasks, and the other with a standalone execution or a real-time OS using the Arm Cortex-R5 cores. The Xen hypervisor and the OpenAMP framework allow this, but they may introduce a delay in the system, and some messages in the smart grid need a latency lower than 3 ms. In this paper, the Linux thread latencies are characterized by the Cyclictest tool. It is shown that when Xen hypervisor is used, this scenario is not suitable for the smart grid as it does not meet the 3 ms timing constraint. Then, standalone execution as the real-time part is evaluated, measuring the delay to handle an interrupt created in programmable logic (PL). The standalone application was run in A53 and R5 cores, with Xen hypervisor and OpenAMP framework. These scenarios all met the 3 ms constraint. The main contribution of the present work is the detailed characterization of each real-time execution, in order to facilitate selecting the most suitable one for each application.
