Even with the help of present schema design tools (e.g. graphical editors, EER model techniques, etc) the task of constructing any non-trival object oriented database schema (OODB) is immense. This paper describes a system, TYPSYS, which automatically produces a type hierarchy from information about the leaf object types (types at leaf level of the hierarchy) which are visible from the database...

Predictive coding provides a computational paradigm for modeling perceptual processing as the construction of representations accounting causes sensory inputs. Here, we developed scalable, deep network architecture predictive that is trained using gated Hebbian learning rule and mimics feedforward feedback connectivity cortex. After training on image datasets, models formed latent in higher are...

Supervised datasets play a central role as standards against which to benchmark long-term progress in computer vision. Over the past decade, the PASCAL [2] and Berkeley segmentation datasets (BSDS) [3] have filled these roles for the object detection and image segmentation tasks, respectively. The type of annotation available for each dataset determines the particular visual subtasks to which i...

Nested object annotation watermarking (NOAWM) has been introduced as a specialization within annotation watermarking, whereby hierarchical object relations are embedded in photographic images and object relations may be of visual-functional or visual-spatial nature [ViSc2006]. All previous work in the NOAWM domain has focused in this first category of relations, which denotes relationships of o...

This paper presents a fast method that computes deformations with fracturing of an object using a hierarchical lattice. Our method allows numerically stable computation based on so-called shape matching. During the simulation, the deformed shape of the object and the condition of fracturing are used to determine the appropriate detail level in the hierarchy of the lattices. Our method modifies ...

A join index hierarchy method is proposed to handle the “goto’s on disk” problem in objectoriented query processing. The method constructs a hierarchy of join indices and transforms a sequence of pointer chasing operations into a simple search in an appropriate join index file, and thus accelerates navigation in object-oriented databases. The method extends the join index structure studied in r...

This paper focuses on the issues of categorical database generalization and emphasizes the roles of supporting data model, integrated data model, spatial analysis and semantic analysis in database generalization. The framework contents of categorical database generalization transformation are defined. The paper presents an integrated spatial supporting data structure, a semantic supporting mode...

The growing number of video servers resulted in desperate need for eeective method to deliver data to users in a timely fashion. Centralized servers are not a cost-eeective solution because of geographical distribution of users. This paper addresses issues related to design of distributed video server (DVS) to support video-on-demand application for a large number of users. We present a hierarc...
