image abstraction is a method of enhancing or highlighting the visualization of main information contents of image and smoothing the other portion. It is quite important for many multimedia applications like cartooning and animation where symbolic presentation matters; hence it is an important part in the field of image processing. In this paper we are proposing a neural network based approach ...

Mobile devices, as a norm, are equipped with multiple network interfaces, viz. cellular, Wi-Fi and bluetooth, with Wi-Max networks on the horizon. These network interfaces have diverse as well as dynamic characteristics in terms of range, bandwidth and power [3]. Our measurement data of connectivity characteristics of WiFi and cellular networks, along with other recently reported research [1, 4...

In this paper, we define a general service abstraction for a network element. The service abstraction is defined in terms of a “service mapping,” which is a montotone operator that maps an arrival process to a lower bound on the corresponding departure process. We consider service mappings which are shift invariant, which includes the previously studied service curve model defined in terms of c...

This is a preliminary report on research towards the development of an abstraction-based framework for decision-theoretic planning using Bayesian networks. We discuss two problems: the representation of sets of probability distributions for Bayesian networks, and the issue of representing and abstracting actions using Bayesian networks. For the first problem, we propose the use of cc-trees to r...

In this paper, we introduce the concept of an exoskeleton as a new abstraction of arbitrary shapes that succinctly conveys both the perceptual and the geometric structure of a 3D model. We extract exoskeletons via a principled framework that combines segmentation and shape approximation. Our method starts from a segmentation of the shape into perceptually relevant parts and then constructs the ...

ion of Linear Consensus Networks with Guaranteed Systemic Performance Measures Milad Siami and Nader Motee⋆ Abstract—A proper abstraction of a large-scale linear consensus network with a dense coupling graph is one whose number of coupling links is proportional to its number of subsystems and its performance is comparable to the original network. Optimal design problems for an abstracted networ...

We have used various manual abstraction techniques to formally verify a transaction ordering property for an IO protocol over bus/bridge networks. In the context of network protocol verification, an abstraction is needed to reduce the unbounded number of network configurations to a small number of representative networks that can be checked using algorithmic methods. The manually derived abstra...
