We present a novel approach for generating stylized artistic rendering of caricatures from a given face image,with the ability to map any one of the main six expressions and control the degree of its expressiveness on the generated caricature. Our method achieves this by manipulating the facial appearance and expressivity of the caricature,using quadratic deformation model representations of facial expressions.A stroke-based non-photorealistic rendering(NPR) engine is developed to generate the output caricature that appears to be a sketch of the original *** NPR engine segments the defined rendering path and generates rectangular strokes that approximate each segment. The stroke properties arc computed by applying geometric image moments on each *** enhance the overall appearance of the caricature,extra strokes are randomly positioned around the rendering *** results show that from an input neutral facial image,expressive rendered caricatures are generated for the facial expressions neutral,smile,sad,fear,surprise,disgust, and *** approach produces very expressive artistically rendered caricatures,and could lead to future research directions in further extending the method to produce pencil sketch rendering of images or rendering 3D characters to generate cartoon-like 3D characters.

Fuzzy control is a nonlinear control method;its performance depends on the fuzzy control rules, quantification factor and the scale factor. Because these multiple objectives are influence with each others, therefore it is very difficult to ensure the control effect only rely on expertise's experience. In this paper, dynamic evolutionary algorithm is adopted to optimize the multi-objectives in fuzzy controller. In dynamic evolutionary algorithm, based on the competitive relationship between particles' free energy and entropy in the phase space system, a new option strategy is put forward which is used to maintain species diversity;furthermore, multi-parent crossover operator is selected. This operator selects some individuals to form a space and then do searching in this space. This algorithm has strong ability to find the solutions of the problem, and it also run quickly compared with other traditional algorithms. Simulation results show that fuzzy controller optimized by the algorithm has good steady-state response time, steady-state error and overshoot. ©2010 IEEE.

Spatial Audio Coding (SAC) is an emerging technology with a distinguishing feature of delivering good even excellent audio quality at monotonic or stereo bitrate of conventional perceptual transform coders. By a systematic exploitation of spatial hearing, Binaural Cue Coding illustrates the power and potentials of SAC in the future for intelligent multimedia services. MPEG Surround, receiving cumulative efforts from industry and academy, strives to build a SAC system with great versatility and high quality. The initial test results of MPEG Surround show its performance advantage over conventional state-of-the-art coders in a wide range of coding configurations.

This paper proposes a mobile station (MS)-controlled fast MAC-layer handover (HO) scheme to reduce the HO latency in Mobile WiMAX. Based on the received signal strength (RSS) from any Base Station (BS), the MS can estimate its present distance from that BS. This capability allows the MS, through utilization of the broadcast messages by its Serving BS (SBS) and through few scannings of the Neighbouring BSs (NBS), to self-track its own direction of motion relative to the SBS and the NBSs and thus look ahead to perform an intelligent choice of the Target BS (TBS) for the impending HO. Simulation studies have shown a considerable reduction in the HO latency in the proposed method.

In this contribution, we present a new application based on fuzzy linguistic information to evaluate the quality of digital libraries. The quality evaluation of digital libraries is defined using users' perceptions on the quality of digital services provided through their Web sites. We assume a fuzzy linguistic modeling to represent the users' perception and apply automatic tools of fuzzy computing with words based on some weighted aggregation operators to compute global quality evaluations of digital libraries.

The current researches to improve the reliability of operating systems have been focusing on the evolution of kernel architecture or protecting against device driver errors. In particularly, the device driver errors are critical to the most of the complementary operating systems that have a kernel level device driver. Especially on special purpose embedded system, because of its limited resources and variety of devices, more serious problems are induced. Preventing data corruption or blocking the arrogation of operational level is not enough to cover the entire problems. For examples, when using device drivers, the violation of function's call sequence can cause a malfunction. Also a violation of behavior rules on system level involves the same problem. This type of errors is difficult to be detected by the previous methods. Accordingly, we designed a system that traces system behavior at runtime and recovers optimally when errors are detected. We experimented in Linux 2.6.24 kernel operating on GP2X-WIZ mobile game player.

Healthcare organisations using the European Foundation for Quality Management (EFQM) Excellence Model for self-assessment have found an opportunity to work more effectively and a powerful driver for improvement. Nevertheless, when these organisations address self-assessment processes for the first time the initial effort needed presents many difficulties. The aim of this paper is to offer a consensus support methodology based on fuzzy logic under a linguistic approach that would undoubtedly contribute to conduct self-assessment processes with questionnaires. We assume qualitative evaluation, through linguistic labels, to facilitate the individual responses, and we use the concept of fuzzy majority to calculate the measures which guide the consensus reaching process.
