Since a soundtrack makes a video clip attractive, adding a soundtrack to a clip is one of the most important processes in video editing. To make a video clip more attractive, an editor of the clip tends to add a soundtrack considering its timing and climax. For example, editors often add chorus sections to the climax of the clip by replacing and concatenating musical bars in an existing song. However, in the process, editors should take naturalness of rearranged soundtrack into account. Therefore, editors have to decide how to replace musical bars in a song considering its timing, climax, and naturalness of rearranged soundtrack simultaneously. In this case, editors are required to optimize the soundtrack by listening to the rearranged result as well as checking the naturalness and synchronization between the result and the video clip. However, this repetitious work is time-consuming. [Feng et al. 2010] proposed an automatic soundtrack addition method. However, since this method automatically adds soundtrack with data-driven approach, this method cannot consider timing and climax which a user prefers.","PeriodicalId":269034,"journal":{"name":"ACM SIGGRAPH 2015 Posters","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127764543","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}

We demonstrate a framework for the Samsung Gear VR headset that allows developers to create a totally immersive AR & VR experience with no need for interfacing with external devices or cables thereby making it a truly autonomous mobile VR experience. The significant benefits of this system over existing ones are - a fully hands free experience where hands could be used for gesture based input, the ability to use the Head Mounted Display (HMD) sensor for improved head and positional tracking and automatic peer to peer network creation for communication between phones. The most important factor in our system is to provide an intuitive way to interact with virtual objects in AR and VR. And users should be able to switch from AR to VR world and vice versa seamlessly.","PeriodicalId":269034,"journal":{"name":"ACM SIGGRAPH 2015 Posters","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134318494","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}

We don't hear it the same way others do, and our brain treats it differently from any other sound we hear [Houde et al. 2002]. Yet its sonority is highly linked to our body and mind, and deeply connected with how we are perceived by society and how we see ourselves. The V3 system (Vocal Vibrations Visualization) offers a interactive visualization of vocal vibration patterns. We developed the hexauscultation mask, a head set sensor that measures bioacoustic signals from the voice at 6 points of the face and throat. Those signals are sent and processed to offer a real-time visualization of the relative vibration intensities at the 6 measured points. This system can be used in various situations such as vocal training, tool design for the deaf community, design of HCI for speech disorder treatment and prosody acquisition but also simply for personal vocal exploration.","PeriodicalId":269034,"journal":{"name":"ACM SIGGRAPH 2015 Posters","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134063215","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}

The processing and management of this massive amount of heterogeneous data consumes enormous resources. We propose an integrated pipeline for 2D/3D data registration aimed at film production, based around the prototype application Jigsaw. It allows users to efficiently manage and process various data types from digital photographs to 3D point clouds. A key step in the use of multi-modal 2D/3D data for content production is the registration into a common coordinate frame (match moving). 3D geometric information is reconstructed from 2D data and registered to the reference 3D models using 3D feature matching [Kim and Hilton 2014]. We present several highly efficient and robust approaches to this problem. Additionally, we have developed and integrated a fast algorithm for incremental marginal covariance calculation [Ila et al. 2015]. This allows us to estimate and visualize the 3D reconstruction error directly on-set, where insufficient coverage or other problems can be addressed right away. We describe the fast hybrid multi-core and GPU accelerated techniques that let us run these algorithms on a laptop. Jigsaw has been used and evaluated in several major digital film productions and significantly reduced the time and work required to manage and process on-set data.","PeriodicalId":269034,"journal":{"name":"ACM SIGGRAPH 2015 Posters","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115539387","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}

We propose a shape restoration pipeline consisting of appropriate methods for automatic fragment reassembly and shape completion.

Shadow Shooter expands the virtual game space to all the walls in a room just as in Jones' \"Room Alive\" [Jones et al. 2014]; however, it does not require large-scale equipment such as multiple projectors. It only requires the e-Yumi 3D device that consists of a real bow's components added to Willis's interface with a mobile projector [Willis et al. 2013].
