This paper presents a new architecture of database to deal with the complex structure and large volume of the spatial data. The object-oriented technology, which has the powerful modeling ability to describe the complex objects, is used to model the spatial objects. The massive storage that is base on the tertiary storage device is preferred to the large volume of spatial data. The deductive ru...

Though the Internet provides a powerful platform for distributed access to data, current standards fail to encompass management of complex information. The ability to mediate between heterogeneous information formats is a key foundation on which more powerful information systems can be built. This paper outlines our efforts in creating a digital object architecture that facilitates the manageme...

The precise specification of software models is a major concern in the model-driven design of object-oriented software. Models are commonly given as graph-like diagrams so that graph grammars are a natural candidate for specifying them. However, context-free graph grammars are not powerful enough to specify all static properties of a model. Even the recently proposed adaptive star grammars cann...

The visual vocabulary is an intermediate level representation which has been proved to be very powerful for addressing object categorization problems. It is generally built by vector quantizing a set of local image descriptors, independently of the object model used for categorizing images. We propose here to embed the visual vocabulary creation within the object model construction, allowing to...

ii Abstract This thesis proposes an object-oriented query language that is more powerful than many existing query languages. The language is formally speciied and its expressive power is demonstrated by giving four translation schemes from other prominent object-oriented query languages. Further, this query language can be supported by a query algebra and both the query language and query algeb...

In this research, two techniques of pixel-based and object-based image analysis were investigated and compared for providing land use map in arid basin of Mokhtaran, Birjand. Using Landsat satellite imagery in 2015, the classification of land use was performed with three object-based algorithms of supervised fuzzy-maximum likelihood, maximum likelihood, and K-nearest neighbor. Nine combinations...

Abstract   In this paper, we propose a new method for kernel based object tracking which tracks the complete non rigid object. Definition the union image blob and mapping it to a new representation which we named as potential pixels matrix are the main part of tracking algorithm. The union image blob is constructed by expanding the previous object region based on the histogram feature. The pote...

     In this article we introduce the notion of textit{Fractal $omega$-operad} emerging from  a natural $omega$-operad associated to any coglobular object in the category of higher operads in Batanin's sense, which in fact is a coendomorphism $omega$-operads. We have in mind coglobular object of higher operads which algebras are kind of higher transformations. It follows that this natural $omeg...

ROL is a deductive object-oriented database system developed at the University of Regina. It supports important object-oriented features such as object identity, complex objects, classes, class hierarchies, multiple inheritance with overriding and blocking, and schema deenition. It also supports structured values such as functor objects and sets, providing powerful mechanisms for representing b...
