Adaptive Algorithm

The experiment results show that a high performance low cost system may be obtained by adapting algorithms and hardware to each other especially for the vision system. Thus configurable and flexible parallel architecture are the key concepts to design vision system. In addition the configurable and flexible parallel vision system provides a platform for developing application and experimenting with high

In this contribution, an adaptive algorithm based on evolutionary computation techniques is designed, developed and applied to the timetabling problem of educational organizations. Specifically, the proposed algorithm has been used in order to create feasible and efficient timetables for high schools in Greece. The algorithm has been tested exhaustively with real-world input data coming from many different high schools and has been compared with several other effective techniques in order to demonstrate its efficiency and superior performance. Simulation results showed that the algorithm is able to construct a feasible and very efficient timetable more quickly and easily compared to other techniques, thus preventing disagreements and arguments among teachers and assisting each school to operate with its full resources from the beginning of the academic year. Except from that, due to its inherent adaptive behavior it can be used each time satisfying different specific constraints, in order to lead to timetables, thus meeting the different needs that each school may have.

Accidents are one of the leading causes of fatalities around the world. An important indicator of survival rates after an accident is the time between the accident and when emergency medical personnel are dispatched to the scene. To eliminate the delay between accident occurrence and first responder dispatch is to use in-vehicle automatic accident detection and notification systems; we propose to develop an android application which will detect the occurrence of accident through android phone which is kept at the deck of the car. The android phone has inbuilt sensors such as accelerometer, rotational sensors etc. whose values will be analyzed for accident detection. Once accident is detected, the application will capture images from the front and rear camera of Android phone & GPS location will be recorded. This data will be combined in SMS and MMS and sent to pre-stored contacts which will inform authorities about accident. Moreover, different cars will have different accident dete...

Event detection is used to classify recorded gaze points into periods of fixation, saccade, smooth pursuit, blink, and noise. Although there is an overall consensus that current algorithms for event detection have serious flaws and that a de facto standard for event detection does not exist, surprisingly little work has been done to remedy this problem. We suggest a new velocity-based algorithm that takes several of the previously known limitations into account. Most important, the new algorithm identifies so-called glissades, a wobbling movement at the end of many saccades, as a separate class of eye movements. Part of the solution involves designing an adaptive velocity threshold that makes the event detection less sensitive to variations in noise level and the algorithm settings-free for the user. We demonstrate the performance of the new algorithm on eye movements recorded during reading and scene perception and compare it with two of the most commonly used algorithms today. Results show that, unlike the currently used algorithms, fixations, saccades, and glissades are robustly identified by the new algorithm. Using this algorithm, we found that glissades occur in about half of the saccades, during both reading and scene perception, and that they have an average duration close to 24 msec. Due to the high prevalence and long durations of glissades, we argue that researchers must actively choose whether to assign the glissades to saccades or fixations; the choice affects dependent variables such as fixation and saccade duration significantly. Current algorithms do not offer this choice, and their assignments of each glissade are largely arbitrary.
