Patent number: 9412020Abstract: Most of large-scale image retrieval systems are based on Bag-of-Visual-Words model. However, traditional Bag-of-Visual-Words model does not well capture the geometric context among local features in images, which plays an important role in image retrieval. In order to fully explore geometric context of all visual words in images, efficient global geometric verification methods have been attracting lots of attention. Unfortunately, current existing global geometric verification methods are either computationally expensive to ensure real-time response. To solve the above problems, a novel geometric coding algorithm is used to encode the spatial context among local features for large scale partial duplicate image retrieval. With geometric square coding and geometric fan coding, our geometric coding scheme encodes the spatial relationships of local features into three geo-maps, which are used for global verification to remove spatially inconsistent matches.Type: GrantFiled: November 9, 2012Date of Patent: August 9, 2016Assignees: Board of Regents of the University of Texas System, Texas State University, University of Science and Technology of ChinaInventors: Qi Tian, Wengang Zhou, Houqiang Li, Yijuan Lu

Silica nanoaggregates and organosilicon complexes and methods of forming them from biomass materials
Patent number: 9359214Abstract: By controlling the pre-treatment of biomass materials and pyrolysis conditions, silica samples with various surface areas and levels of crystallinity were synthesized. With proper treatment, biogenic silica nanoaggregate (25-30 nm in diameter) can be synthesized from biomass materials. The characterizations revealed that the silica nanoaggregates were composed of smaller primary silica nanoparticles (ca. 4.2 nm in diameter). Under controlled melting catalyzed by metal salt cations, the silica nanoaggregates may be fuse to form semi-crystalline porous silica frameworks with tunable pore size and structural integrity. Organosilicon complexes were synthesized from the bio derived silica nanoaggregates.Type: GrantFiled: February 28, 2012Date of Patent: June 7, 2016Assignee: Texas State University-San MarcosInventors: Luyi Sun, Weixing Wang -
