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":"40 1","pages":"0"},"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}

Fryazinov","doi":"10.1145/2787626.2787660","DOIUrl":"https://doi.org/10.1145/2787626.2787660","url":null,"abstract":"With the increasing quality of real-time graphics it is vital to make sure assets move in a convincing manner otherwise the players immersion can be broken. Grass is an important area as it can move substantially and often takes up a large portion of screen space in games. Animation of grass is a subject to academic research [Fernando 2004; Perbet and Cani 2001] as well as a technology which is implemented in a number of video games. The list includes, but is not limited to, games such as Far Cry 4, Battlefield 4, Dear Esther and Unigine Valley. Comparing video games assets with reality, it can be seen that the current methods have a number of problems which decrease the realism of the resulting grass animation. These problems include: 1) the visible planar nature of grass geometry and 2) problems with the grass movement which include over-connectivity of grass blades in respect to their neighbours, no obvious wind direction and exaggerated swaying motions. In this paper we propose to increase realism of the grass by focusing on its movement. The main contributions of this work are: 1) Distinguishing ambient and directional components of the wind and 2) The method for calculating directional wind by using a grayscale map and wind vector. The grass was implemented with vertex shaders in line with the majority of methods described in academic literature (e.g. [Fernando 2004]) and implemented in modern games.","PeriodicalId":269034,"journal":{"name":"ACM SIGGRAPH 2015 Posters","volume":"130 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133274530","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":"16 1","pages":"0"},"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}
