We present a systematic study on the recognition of 3D gestures using spatially convenient input devices. Specifically, we examine the linear acceleration-sensing Nintendo Wii Remote coupled with the angular velocity-sensing Nintendo Wii MotionPlus. For the study, we created a 3D gesture database, collecting data on 25 distinct gestures totalling 8500 gestures samples. Our experiment explores how the number of gestures and the amount of gestures samples used to train two commonly used machine learning algorithms, a linear and AdaBoost classifier, affect overall recognition accuracy. We examined these gesture recognition algorithms with user dependent and user independent training approaches and explored the affect of using the Wii Remote with and without the Wii MotionPlus attachment. Our results show that in the user dependent case, both the AdaBoost and linear classification algorithms can recognize up to 25 gestures at over 90% accuracy, with 15 training samples per gesture, and up to 20 gestures at over 90% accuracy, with only five training samples per gesture. In particular, all 25 gestures could be recognized at over 99% accuracy with the linear classifier using 15 training samples per gesture, with the Wii Remote coupled with the Wii MotionPlus. In addition, both algorithms can recognize up to nine gestures at over 90% accuracy using a user independent training database with 100 samples per gesture. The Wii MotionPlus attachment played a significant role in improving accuracy in both the user dependent and independent cases.

A new hand-dorsa vein recognition method based on Partition Local Binary pattern (PLBP) is presented in this paper The proposed method employs hand-dorsa vein images acquired from a low cost near infrared device After preprocessing the image is divided into sub images LBP uniform pattern features are extracted from all the sub images which are combined to form the feature vector for token vein texture features The method is assessed using a similarity measure obtained by calculating the Chi square statistic between the feature vectors of the tested sample and the target sample Integral histogram method original LBP and Partition LBP with 16 32 64 sub-images are tested on a database of 2040 Images from 102 individuals built up by a custom-made acquisition device The experimental results show that Partition LBP performs better than original LBP Circular Partition LBP performs better than Rectangular Partition LBP and when the image was divided into 32 performs better than others

This research adopts "A pattern Language" as a basis, proposed by Christopher Alexander, an architectural theorist who thinks a designer can extend more design patterns if he can pass on the developed design knowledge and accumulate the results. On the other hand, the Agent-Oriented Design is a new generation method of programming design that mainly uses the script language as a basis for development and that is suitable to design the multi-agent application system. Based on the above research background, each "spatial object" in the space defined in this research is called "agent", and the so-called "pattern" refers to "a feasible way of assembly among agents of spatial objects". A pattern can be regarded as the one similar to "the concept of script function". Supposing each agent of spatial object can have its own behavioral mechanism, "coordinative agents" responsible for coordinative function of behavior need to be added if excellent coordination is required for action dependencies among the agents when a script function is executed;that is, to complete a "design goal". Therefore, the purpose of this research is to propose "a communicative and coordinative mechanism of agents of spatial objects" by establishing this pattern-oriented design agent.

Life and argues that the (relational) management of data can be understood as a chemical model. Whereas each data itself is consistent with atomic entities, each combination of data corresponds to a (artificial) molecular structure. For example, an attribute D inside a relational system can be represented by a nucleus ap sharing a cloud of values, which consists of so-called valectrons (the values for the column D). By using reaction rules like the selection of tuples or projection of attributes, a retrieve of molecules can be achieved quite easily. Advantages of the chemical model are no data types, a fast data access, and the associative nature of the molecules: this automatically supports a direct identification of patterns in the sense of data mining. A disadvantage is the need for restructuring that must eventually be done, because the incoming data stream is allowed to influence the chemical model. With this position paper, we present our basic concept.
