  • GML Database Based on Oracle XML DB

    Based on the study of XML documents storage in Oracle XML DB, this paper conducts a research on extending Oracle XML DB to store and manage GML documents. Meanwhile, owing to the defects that the XML DB cannot support the spatial index, an external R-Tree index is added to Oracle database to improve the efficiency of GML spatial query and operation. At the same time, with the help of NTS as well as with Oracle's own support XQuery, the spatial extension to XQuery in Oracle is proposed and implemented. Through the research of this paper, we provide a solution of GML database for GML storage, index and query.

  • Combination of Partition Table and Grid Index in Large-Scale Spatial Database Query

    The performance of retrieval and query of massive spatial data has been a bottleneck in GIS applications. Calculation and determination of the grid cell size is the key to grid index technology which generates obvious effects on improving query performance on large-scale geographic database. This paper studies how the grid cell size impacts on grid index performance indicators through a series of experiments. In essence, Partition Table and Partition Index is an abnormality of grid index which has large-scale grid cell. This article has combined the partition table and partition index with grid index through dividing the data by larger grid, thus each division forms an independent data storage partition and range query is converted into or limited to local query, consequently more effective multi-layered grid index has been created under the environment of huge amounts of data. Through experimental verification, testing results show that the combined index for the massive spatial data queries have obvious effects and can greatly improve the efficiency of spatial query.

  • Time efficiency optimization technique of mass data rendering by Mobile GIS

    Because of low processing speed of CPU and small memory space, time efficiency of portable hardware, where Mobile GIS is running, is low when processing the mass data. A variety of plans, which can improve the time efficiency of rendering the mass data by application software at user side of Mobile GIS, were studied in terms of development language selection, rendering process control, memory mapping, as well as special processing of different data formats. These technical plans were practiced in case studies based on the system platform of Windows Mobile and the development language of C++. Development strategies we got will improve the time efficiency of mass data rendering by Mobile GIS and make it easy to operate for users.

  • Sigma nigma: an image retrieval system

    Presents a system which retrieves images on the basis of automatically generated indexes (i.e. semantic image representations, obtained by automatic image analysis, indicating the content of the images). The system consists of two parts: an off-line indexing part and an on-line image retrieval part. The indexing component is used to automatically generate semantic representations of images so that the image retrieval component can use this information to enable image retrieval. The man-machine communication of the image retrieval component is based on an iconical graphical query language to accomplish geographical query specification for image access. Experiments have been carried out on three different sets of images from the following domains: MRI images of the chest, electronic schemas and topographic maps. The experiments show encouraging results especially for domains which have a high degree of formality in their pictorial expression, such as electronic schemas and topographic maps, and to a less extent for domains having a weak degree of formality such as MRI images of the chest.<<ETX>>

  • A Kind of Clustering Algorithm Based on N-Tree

    Due to the problem of the excessive time complexity in multi-dimension data- processing based on density algorithm, this paper proposes a clustering algorithm based on n-tree spatial index structure, which can realize the quick judgment of adjacent units of any unit through the reasonable encoding to the segmented units. By adopting the pruning in n-tree generating process, this algorithm can effectively save the cost of CPU and I/O. Compared with DBSCAN algorithm by different dimensions experiments, this algorithm can largely increase the capacity of processing massive, high-dimension set.

  • Spectral analysis and unsupervised SVM classification for skin hyper-pigmentation classification

    Data reduction procedures and classification via support vector machines (SVMs) are often associated with multi or hyperspectral image analysis. In this paper, we propose an automatic method with these two schemes in order to perform a classification of skin hyper-pigmentation on multi-spectral images. We propose a spectral analysis method to partition the spectrum as a tool for data reduction, implemented by projection pursuit. Once the data is reduced, an SVM is used to differentiate the pathological from the healthy areas. As SVM is a supervised classification method, we propose a spatial criterion for spectral analysis in order to perform automatic learning.

  • Spatio-temporal indexing of vector quantized video sequences

    Visual (image and video) database systems require efficient indexing to enable fast access to the images in a database. In addition, the large memory capacity and channel bandwidth requirements for the storage and transmission of visual data necessitate the use of compression techniques. Vector quantization (VQ) is an efficient technique for low bit-rate image and video compression. In addition, the low complexity of the decoder makes VQ attractive for low power systems and applications which require fast decoding. In this paper, we present an indexing technique for compressed video using vector quantization. Here, a video sequence is first compressed using VQ. Each frame is represented by a usage map, a set of VQ labels, and a set of motion vectors. The video sequence is partitioned into shots and the various camera operations and motion within each shot are then determined by processing the VQ label maps. Each shot is indexed using a spatio-temporal index. The spatial index refers to the spatial content of the representative frame of a shot, while the temporal index represents the temporal content of the shot. The spatial index is based on the codewords used to compress the representative frame, while the temporal index is based on motion and camera operations within the shot. The proposed indexing technique is executed entirely in the compressed domain. This entails significant savings in computational and storage costs resulting in faster execution.

  • Models and Optimization Methods of Spatial Query on Multi-platforms

    In this paper, the spatial query models of multi platforms are analyzed. A 2-level MBR filter spatial join method (2FSJM) is proposed, which improves the performance of multi-platforms, including Oracle Spatial, ArcSDE and the open source platform OGR/GEOS. The experiments on multi-platforms are implemented. The results show that the improvement is valid.
