[email protected], [email protected], [email protected] Abstract: This paper is a literature survey paper of our system which will help advertisers to get some sort of feedback about their advertisement. Advertisement is a form communication which helps to promote a product in an attempt to induce consumers purchase that product. Advertisement are basically displayed to increase the awareness about brands that are introduced in the market or to demonstrate the differences between the products available and the competing products in order to increase their sell.Advertisement helps to get insight of the product. Now a days billboards are preferred to display advertisements in malls. Billboards are effective way of advertising as they are more attractive and noticeable. However it is not possible for advertisers to know the public response for those ads on the billboards thus creating a bottleneck. Our system helps in getting some chunk of that response from the people who are interested in the displayed ads and crunching that data to give advertisers a true feedback for their ads on the billboard. This system includes real-time detection of multiple faces and tracking of those detected faces which will be used to calculate the amount of time person spends in front of the given billboard. It also includes nose and eyes tracking to know whether the viewer's attention is at billboard or outside it. We will be even using calibrated stereo camera for depth estimation that is for knowing at what distance is the viewer from the camera. The timer will be implemented to know time spent by individual in front of the billboard. The data is being analyzed and converted in the form of statistics and visual information such as graphs to provide advertisers valuable feedback for their ads. The statistics which will be viewed after number of faces being detected and time average evaluation for each face which will help the advertiser with the scope of improvement in the advertisement and increase in profit.

INTRODUCTION. advertisement or announcement, a billboard is usually found Advertising is a form of communication which helps outdoors along roadways, malls etc where number of people people to know about the new products or services in the visit is large in number. Advantage of displaying market and help them to purchase the better ones by giving advertisement through billboards is it is more noticeable and the overview of the product. It plays a vital role in deciding reaches to large number of people as it is large in size and the growth of the company by means of sale, production, displayed in public places. Billboard advertisement can be revenue, popularity etc. Shopping centres, malls offer vast, placed wherever we feel it will have the high impact. This can often untapped opportunities to earn money by advertising be a huge advantage when we have a business we want to products, brands, services etc. As likely said malls are the draw traffic to rightly by some other path, or we have a shop better places to advertise because it does not emphasize only just down the road. on limited products but give user the exposure to numerous other products by making a variety of options available. Advertising is the way for advertiser to get engaged with the consumers on the issues related to product by detailing it. It can help to build trust between the customer and the product. Advertising is being viewed as a technique of mass promotion in which single message can reach to large number of people. Advertising is also being considered a one-way technique of marketing where the customer is not in position to immediately respond to the advertisement. If you want your advertisement to hit on the day a product launches or event is about to happen, this is the only vehicle you control completely. Advertisements are in various forms such as emails, newspapers, web pages, radio, television, magazines. Fig 1: System Overview Outdoor advertisements are actually the ones which reach to large number of people and can easily catch the attention of Nowadays billboards are the most trending ways to display an the person passing by it. They are displayed outdoor on roads, advertisement in malls because of its visual impact on the malls etc. Outdoor advertisements are in the form of user. Billboards are more appealing and make your hoardings, posters, billboards, electronic displays etc. A flat advertising more noticeable. This motivated us to develop a panel or we can call it as a board that holds some kind of International Journal of Engineering Science and Computing, March 2016 2775 http://ijesc.org/ system that helps them understand the response of the user to where they spend the maximum time in the store, when and the billboards placed in malls and in turn help them to what they shop and what they look at are all tools that help in understand the needs and interests of the onlooker.

    Multimedia Content Analysis: The Next Wave View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by CiteSeerX Nevenka Dimitrova Philips Research, 345 Scarborough Rd., Briarcliff Manor, NY 10510, USA [email protected] Abstract. We have witnessed a decade of exploding research interest in multimedia content analysis. The goal of content analysis has been to derive automatic methods for high-level description and annotation. In this paper we will summarize the main research topics in this area and state some assumptions that we have been using all along. We will also postulate the main future trends including usage of long term memory, context, dynamic processing, evolvable generalized detectors and user aspects. 1 Introduction After a decade of exploding interest in the multimedia content analysis and retrieval [1,6,8,15], there has been enough research momentum generated that we can finally reflect on the overall progress. The goal has been to develop automatic analysis tech- niques for deriving high level descriptions and annotations, as well as coming up with realistic applications in pursuit of the killer application. Meanwhile the MPEG-7 has standardized the description of metadata – data describing information in the content at various levels. Applications range from home media library organization that con- tains volumes of personal video, audio and images, multimedia lectures archive, con- tent navigation for broadcast TV and video on demand content. The tools have emerged from traditional image processing and computer vision, audio analysis and processing, and information retrieval. In this paper we will first present an overview of the active research areas in video content analysis in Section 2.

    Multimedia Tools and Applications https://doi.org/10.1007/s11042-019-07793-w Big data analytics for video surveillance Badri Narayan Subudhi1 & Deepak Kumar Rout2 & Ashish Ghosh3 Received: 1 September 2018 /Revised: 19 March 2019 /Accepted: 15 May 2019 # Springer Science+Business Media, LLC, part of Springer Nature 2019 Abstract This article addresses the usage and scope of Big Data Analytics in video surveillance and its potential application areas. The current age of technology provides the users, ample opportunity to generate data at every instant of time. Thus in general, a tremendous amount of data is generated every instant throughout the world. Among them, amount of video data generated is having a major share. Education, healthcare, tours and travels, food and culture, geographical exploration, agriculture, safety and security, entertainment etc., are the key areas where a tremendous amount of video data is generated every day. A major share among it are taken by the daily used surveillance data captured from the security purpose camera and are recorded everyday. Storage, retrieval, processing, and analysis of such gigantic data require some specific platform. Big Data Analytics is such a platform, which eases this analysis task. The aim of this article is to investigate the current trends in video surveillance and its applications using Big Data Analytics. It also aims to focus on the research opportunities for visual surveillance in Big Data frameworks. We have reported here the state-of-the-art sur- veillance schemes for four different imaging modalities: conventional video scene, remotely sensed video, medical diagnostics, and underwater surveillance. Several works were reported in this research field over recent years and are categorized based on the challenges solved by the researchers.

Since most of the recent advances regarding the extraction of information from images and video rely on computation heavy deep learning algorithms, there is a growing need for solutions that allow the deployment and use of new models on scalable and flexible edge architectures. In this work, we present Deep-Framework, a novel open source framework for developing edge-oriented real-time video analytics applications based on deep learning. Deep-Framework has a scalable multi-stream architecture based on Docker and abstracts away from the user the complexity of cluster configuration, orchestration of services, and GPU resources allocation. It provides Python interfaces for integrating deep learning models developed with the most popular frameworks and also provides high-level APIs based on standard HTTP and WebRTC interfaces for consuming the extracted video data on clients running on browsers or any other web-based platform.

Video surveillance plays an increasingly important role in public security and is a technical foundation for constructing safe and smart cities. *e traditional video surveillance systems can only provide real-time monitoring or manually analyze cases by reviewing the surveillance video. So, it is difficult to use the data sampled from the surveillance video effectively. In this paper, we proposed an efficient video detection object super-resolution with a deep fusion network for public security. Firstly, we designed a super-resolution framework for video detection objects. By fusing object detection algorithms, video keyframe selection al- gorithms, and super-resolution reconstruction algorithms, we proposed a deep learning-based intelligent video detection object super-resolution (SR) method. Secondly, we designed a regression-based object detection algorithm and a key video frame selection algorithm.

IV automatically analyzes the video stream and extracts useful information from images such as detected intruders. The typical applications are video motion detection, video pattern matching and auto tracking. Today, security departments deploy more and more surveillance cameras to watch broader areas closely 24 hours a day and 7 days a week. IP technology enables building open, reliable and scalable surveillance systems. While video data is increasing, one person can only watch a limited amount of video data. People quickly lose their ability to concentrate and suspicious movements on the screen are frequently overlooked. Intelligent Video works 24 hours a day without stopping, improving surveillance accuracy and effectiveness. Another way to use Intelligent Video is to change the video data to a gold mine for business. Customer behavior is recorded on the video and contains valuable information for improving marketing effectiveness, store operations, building layout designs, traffic patterns and more.
