In this work, we present a novel method for accurate affine transformation estimation of image regions. We illustrate the benefits of using such a method in a point matching mechanism that enables locating large amount of point matches with high geometric precision and low rate of false matches. Recent publications have shown that considering the affine transformation model of local regions, is extremely...
The importance of the analysis and understanding of the network traffic has constantly been increasing due to insights that this provides towards determination of user behaviour and resource usage. The data analyses in order to determine the related parameters are performed by selection of a small subset of the complete flow data due to data privacy and heavy computational/memory load issues. That...
An intrusion detection system (IDS) inspects all inbound and outbound network activity and identifies suspicious patterns that may indicate a network or system attack from someone attempting to break into or compromise a system. A networkbased system, or NIDS, the individual packets flowing through a network are analyzed. In a host-based system, the IDS examines at the activity on each individual...
The heart is the most important of the vital organs and heart diseases may cause fatal consequences. Abnormal heart sounds called murmur may be a precursor of many serious heart diseases. Cardiac auscultation is a basic technique to easily diagnose murmur disease. Auscultation can be supported by using computer aided automatic diagnosis systems to fast and accurate diagnosis. These systems are useful...
Script identification is a complex real life problem for automation of printed or handwritten document processing. The task becomes more challenging when it comes about a multi script/lingual country like India. For the development of OCR for a particular language the script needs to be identified first. That is why development of a script identification system is a pressing need. Till date no such...
This paper presents a comparison between different signal processing algorithms applied to a gyro-based computer head mouse for persons with movement disorders. MEMS-gyros can be used to sense the head movement and rotation. However, the measured gyro signals are influenced by noise, offset, drift and especially temperature drift. Thus, there is a need to improve the signal by signal processing algorithms...
Lot of applications today employ multipliers to do many simple and complex jobs, from mathematical calculations to signal processing. But we only employ lower order compressors for this operation. This gives us lot of delay. The proposed paper puts to usage, higher order compressors for the same purpose. This results in reduced delay and improves efficiency greatly.
Constraint optimization exists in many natural-computation applications, including neural and evolutionary computations. A key observation on the constraints of many of these application problems is that they are highly structured and involve variables with strong spatial or temporal locality. Based on this observation, large-scale problems in these applications can be partitioned by their constraints...
Cognitive radio (CR) is a technology that addresses the problem of scarcity of spectrum and paves the way for efficient use of the same. In recent times, it has been observed that most research is focused on building theoretical models which are backed mostly by simulation results. In order to successfully support any theoretically developed model, it is necessary that the algorithm be tested in practical...
The talk deals with a new paradigm for multimedia search based on content. We present an alternative approach to classical search engines for information retrieval which can be used for large and generic multimedia repositories. We introduce an incremental evolution scheme within a collective network of (evolutionary) binary classifier (CNBC) framework. The proposed framework addresses the problems...
Sensor arrays have been used in a variety of sensing and communications applications. The spatial dimension can be utilized for user separation and improved reception through the placement of multiple antenna elements at the receiver and/or the transmitter and appropriate signaling when possible. Further, the ubiquity of wireless transmitters has provided the opportunity for location-based services,...
With the vigorous development of technology, more and more people rely on various computer and 3C products. Computer can enrich our live to make our thinking more colorful, but it is limited to the indoor environment because computer is not easy to carry anywhere, even for the notebook. For this reason, more kinds of 3C products with a small size have gradually increased then become the primary choice...
Play is a vital activity in which children observe the world, learn new concepts and experiment with them. Even though the social aspect of play is very important, the computer science community has struggled to address it. Digital playgrounds have been built in which children can play in technologically enhanced installations, but the detailed study of the social component of play within these installations...
Dataflow methods are widely used for the design and implementation of signal processing functionality in cyber-physical systems. Systematically integrating instrumentation methods into dataflow-based design processes is important to facilitate trade-off assessment and tuning of alternative scheduling strategies. Such instrumentation-driven scheduler development is particularly important for dynamically...
This paper described the signal from the eye muscles that is called electrooculogram which is generated at different eye movement's directions and levels. The eye movement signal data is captured by using Al/AgCl electrodes and passed through the g.USBamp from G.TEC Medical Engineering GMBH eye movement data collection. The eye movement data is passed to the Matlab/Simulink software for data analysis...
Social signal processing has the ambitious goal of bridging the social intelligence gap between computers and humans. Nowadays, computers are not only the new interaction partners of humans, but also a privileged interaction medium for social exchange between humans. Consequently, enhancing machine abilities to interpret and reproduce social signals is a crucial requirement for improving computer-mediated...
With the help of pervasive computing, nowadays it is possible to gather user preference of physical items based on natural interaction, i.e., recognizing and recording user's actual choosing behavior by sensors, then analyzing the history to learn his/her current preference. In this paper, we propose a method based on this idea and implement a prototype to collect and apply the dietary preference...
Data acquisition and measurement engineering can get the operation status of machine, detect the potential threat and failure preLiminarily and predict the Life of machine for equipment management.
