Procedural content generation for games: A survey
Mark Hendrikx, Sebastiaan Meijer, Joeri Van Der Velden, Alexandru Iosup
Article No.: 1
DOI: 10.1145/2422956.2422957

Hundreds of millions of people play computer games every day. For them, game content—from 3D objects to abstract puzzles—plays a major entertainment role. Manual labor has so far ensured that the quality and quantity of game content...

Image retrieval with query-adaptive hashing
Dong Liu, Shuicheng Yan, Rong-Rong Ji, Xian-Sheng Hua, Hong-Jiang Zhang
Article No.: 2
DOI: 10.1145/2422956.2422958

Hashing-based approximate nearest-neighbor search may well realize scalable content-based image retrieval. The existing semantic-preserving hashing methods leverage the labeled data to learn a fixed set of semantic-aware hash functions. However, a...

GPSView: A scenic driving route planner
Yan-Tao Zheng, Shuicheng Yan, Zheng-Jun Zha, Yiqun Li, Xiangdong Zhou, Tat-Seng Chua, Ramesh Jain
Article No.: 3
DOI: 10.1145/2422956.2422959

GPS devices have been widely used in automobiles to compute navigation routes to destinations. The generated driving route targets the minimal traveling distance, but neglects the sightseeing experience of the route. In this study, we propose an...

SIFT match verification by geometric coding for large-scale partial-duplicate web image search
Wengang Zhou, Houqiang Li, Yijuan Lu, Qi Tian
Article No.: 4
DOI: 10.1145/2422956.2422960

Most large-scale image retrieval systems are based on the bag-of-visual-words model. However, the traditional bag-of-visual-words model does not capture the geometric context among local features in images well, which plays an important role in...

Identification of scene locations from geotagged images
Jong-Seung Park, Ramesh Jain
Article No.: 5
DOI: 10.1145/2422956.2422961

Due to geotagging capabilities of consumer cameras, it has become easy to capture the exact geometric location where a picture is taken. However, the location is not the whereabouts of the scene taken by the photographer but the whereabouts of the...

Region- and action-aware virtual world clients
Yichuan Wang, Ting-An Lin, Cheng-Hsin Hsu, Xin Liu
Article No.: 6
DOI: 10.1145/2422956.2422962

We propose region- and action-aware virtual world clients. To develop such clients, we present a parameterized network traffic model, based on a large collection of Second Life traces gathered by us. Our methodology is also applicable to virtual...

Spider: A system for finding 3D video copies
Naghmeh Khodabakhshi, Mohamed Hefeeda
Article No.: 7
DOI: 10.1145/2422956.2422963

This article presents a novel content-based copy detection system for 3D videos. The system creates compact and robust depth and visual signatures from the 3D videos. Then, signature of a query video is compared against an indexed database of...

Web-accessible geographic integration and calibration of webcams
Austin Abrams, Robert Pless
Article No.: 8
DOI: 10.1145/2422956.2422964

A global network of webcams offers unique viewpoints from tens of thousands of locations. Understanding the geographic context of this imagery is vital in using these cameras for quantitative environmental monitoring or surveillance applications....
