The acquired data has different and complementary natures, combining geometry with visual attributes. For this reason, Kinect is a flexible tool that can be used in applications from several areas such as: Computer Graphics, Image Processing, Computer Vision and Human-Machine Interaction. In this way, the Kinect is a widely used device in industry (games, robotics, theater performers, natural interfaces, etc.) and in research. We will initially present some concepts about the device: the architecture and the sensor. We then will discuss about the data acquisition process: capturing, representation and filtering. Capturing process consists of obtaining a colored image (RGB) and performing a depth measurement (D), with structured light technique. This data is represented by a structure called RGBD Image. We will also talk about the main tools available for developing applications on various platforms. Furthermore, we will discuss some recent projects based on RGBD Images. In particular, those related to Object Recognition, 3D Reconstruction, Augmented Reality, Image Processing, Robotic, and Interaction. In this survey, we will show some research developed by the academic community and some projects developed for the industry. We intend to show the basic principles to begin developing applications using Kinect, and present some projects developed at the VISGRAF Lab. And finally, we intend to discuss the new possibilities, challenges and trends raised by Kinect.","PeriodicalId":239862,"journal":{"name":"2012 25th SIBGRAPI Conference on Graphics, Patterns and Images Tutorials","volume":"380 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114890621","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At the same time, the Web browser has become an application platform. Mobile+Cloud, the combination of mobile devices and cloud-based computing is changing how users produce, consume, and use computing resources. With the introduction and penetration of HTML5, and, in particular, its visual capabilities in the form of the Canvas element, the implementation of high-quality browser-based graphics has become a reality. Indeed, WebGL offers capabilities comparable to the traditional (desktop) OpenGL utilizing in browser computing resources. It is now feasible to have high performance graphics and visualization \"in your palm, \" utilizing a mobile device's browser as the graphics platform as well as the front end interface and the display. In the near future, graphics'\"heavy lifting\" on a cloud-based platform, coupled with a mobile client will afford high-performance graphics for most users most of the time. We argue that this will become the most common platform for computer graphics and visualization in the not too-distant future. We further argue that such platforms will democratize the use of advanced graphics and visualization and will revolutionize analysis and display of the growing amount of data we all face every day. The goals of this survey are to make the reader familiar with the underlying technologies that make this possible, including(but not limited to) cloud-based computing, mobile computing, their combination, HTML5 and the Canvas element, the Web Gland other graphics libraries, and general Web-based graphics and visualization.","PeriodicalId":239862,"journal":{"name":"2012 25th SIBGRAPI Conference on Graphics, Patterns and Images Tutorials","volume":"PP 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126400295","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
