In this paper, an efficient content-based copy detection (CBCD) method using the signs of the Discrete Cosine Transform (DCT) coefficient (S-DCT) is proposed. The S-DCTs are extracted from DC images. The proposed method uses a small-size feature, i.e., 48 bits/image, nevertheless, it resulted in neither false-negatives nor false positives. The proposed method can handle common alterations in CBCD application, such as contrast and gamma changing, noise addition, resizing, and a slight shifting. It is confirmed that the efficiency and accuracy of the proposed method are superior to those using the MPEG-7 color layout descriptor, one of the smallest image descriptors.

This paper describes the effect of alpha, α and gamma,γ changes to the motion of photon in a Fiber Bragg Grating. The study has been successfully performed under Bragg resonance condition where the initial frequency of the light,W0 has the same value with the Bragg frequency, WB. The Stokes parameter is chosen to provide important information about the total energy and energy difference between the forward and backward propagating modes. The motion of a particle moving is shown with the classic anharmonic potential where the beta, β is set to zero due to power conservation along the grating structures.

In the past, efforts have been devoted to the amelioration of motion estimation algorithms to speed up motion compensated video coding. Now, efforts are increasingly being directed at exploiting the underlying architecture, in particular, single instruction, multiple data (SIMD) instruction sets. The resilience of motion estimation algorithms to various error metrics allows us to propose new high performance approximate metrics based on the sum of absolute differences (SAD). These new approximate metrics are amenable to efficient branch-free SIMD implementations which yield impressive speed-ups, up to 11:1 in some cases, while sacrificing image quality for less than 0.1 dB on average.

Skin surface roughness can be changed due to skin lesion progression. The evaluation of the damage of the skin is assessed on the base of clinical experience of dermatologists. Currently, the assessment of skin surface is made by running a finger across the skin. It is found that this tactile evaluation may result in inter and intra variations. The objective of our research is to develop an objective assessment tool in evaluation skin roughness. Psoriasis is used as a sample of skin lesion that can change skin surface roughness as its extents develop. 3D surface images of 120 psoriasis lesions scanned from 29 patients are analysed in the study. The lesions are previously grouped into four categorises based on its tactile characteristics by dermatologists. The proposed method converts the 3D images into 2D height maps. The 2D height maps are then fitted and filtered using averaging filter. Finally, Mean Square Error (MSE) between the fitted and filtered 2D height maps are computed and utilized as skin roughness descriptors. Results show that the proposed method has been able to differentiate each lesion according to its group perfectly.

Location estimation as one of the most popular research areas has been recently attended because of wide range of its applications. K Nearest Neighbor (KNN) is a basic deterministic algorithm for locating which is widely used in fingerprinting approach. The performance of the KNN can be improved extensively by employing appropriate selection algorithm. In this paper, a novel algorithm called Dynamic KNN (D-KNN) which uses Angle of Arrival (AOA) and KNN as a hybrid method is proposed. This method comparing with KNN algorithm with constant K, selects the best number of nearest neighbors dynamically. It utilizes the adaptive antenna system to determine the user locative area by intersection of several obtained AOA. The best K neighbors which are located in the determined area can be selected to employ in the KNN. Analysis and simulation results are reported the best overall performance of D-KNN in different conditions.

The Paper presents the outlines of the Field Programmable Gate Array (FPGA) implementation of Real Time speech enhancement by Spectral Subtraction of acoustic noise using Dynamic Moving Average Method. It describes an stand alone algorithm for Speech Enhancement and presents a architecture for the implementation. The traditional Spectral Subtraction method can only suppress stationary acoustic noise from speech by subtracting the spectral noise bias calculated during non-speech activity, while adding the unique option of dynamic moving averaging to it, it can now periodically upgrade the estimation and cope up with changes in noise level. Signal to Noise Ratio (SNR) has been tested at different noisy environment and the improvement in SNR certifies the effectiveness of the algorithm. The FPGA implementation presented in this paper, works on streaming speech signals and can be used in factories, bus terminals, Cellular Phones, or in outdoor conferences where a large number of people have gathered. The Table in the Experimental Result section consolidates our claim of optimum resouce usage.

The current trend set by service providers of enhancing the degree of provisions in IP networks while maintaining the optimum quality, has promoted many research activities. These activities include those which aim to introduce improved quality of services for popular Internet services and applications. In this paper, quality of services (QoS) of video transmission on Differentiated Services (DiffServ) with multiprotocol label switching (MPLS) network is being simulated and evaluated by a network Simulator, OPNET. The need of integration of MPLS with DiffServ particularly for the video traffic has been demonstrated in the simulation. The objective of this work is to study the influence of the QoS mechanism via DiffServ-MPLS on network parameters such as packet loss, delay and throughput for different video resolutions. The comprehensive study showed general improvement in the throughput and packet loss particularly of video transmission when using DiffServ-aware MPLS network as compared to when only MPLS or DiffServ is employed.

Identification of a system arranged by a variable speed drive, an induction motor, and a dynamometer is conducted. The system is considered as a MISO. The system has two inputs i.e. variable speed drive control voltage and load applied and one output that is speed. Input-output data is used to build a model. Multi-level periodic perturbation signal is considered to the inputs. By using system identification toolbox, process model provides good model and it is indicated by fit value. The result shows that by using multi-level periodic perturbation signal, simulation of the model gives close performance to the measured data.
