This paper reviews Kunchenko's polynomials using as template matching method to recognize template in one-dimensional input signal. Kunchenko's polynomials method is compared with classical methods — cross-correlation and sum of squared differences according to numerical statistical example.
The paper considers the problem of processing and forecast of dynamic images in real time. The suggested approach to the formation of reference tunnel provides the technique, intended for information processing, realization of which laser beams centres are calculated with higher accuracy, route images are classified to provide more accurate forecast of their further behaviour.
Topology free structure of scanning electron microscopy images of heat treated, metallized compound semiconductor surfaces are studied using structural entropy based analysis. The scale dependence and the possible superstructures are determined by wavelet transforming the images before the localization type detection. The studied images are taken in-situ during a thermalization experiment, using GaAs...
This paper present the relationship between the performance of the analog-to-digital converter (ADC) and the digital FPGA and/or IC based π/4 DQPSK. As such, the ADC resolution and the ADC sampling rate are analyzed. As a result, ADC parameters for 20 Mb/s data rate were selected.
Thyroid diseases, in general, and in particular thyroid cancer can be detected by infrared built-in image processing. A good spatial resolution is needed to assess the specific patterns, but small signal-to-noise ratio and low contrast makes much difficult to achieve infrared image denoising and edge enhancement. This paper proposes an improved method of anisotropic diffusion filtering which reduces...
Biometric recognition significantly evolved during the last decade and today is used on daily basis. Despite active research in this area it is very hard for scientists to compare their results with others mainly because of different implementations and environment conditions. In this paper, we present modular biometric system based on universal schema of biometric recognition process. Modular architecture...
Construction of an embedded position measurement sensor based on the real-time image processing and a low-cost CMOS image sensor is presented in this work. Position measurement task is simplified with the use of assisted videometry concept — the target object is equipped with an additional marker (active or passive). An effective implementation of algorithm for the marker position estimation for Digital...
Optimum channel/frequency allocation problem in a general mobile radio networks is well-known to be NP-complete. The optimum general solution for a mobile radio network for even 2-channel case is not known. In this paper, we focus on the case L=2k where L is the number of channels/frequencies and k is a positive integer. In order to minimize the sum of the network level interference, we show that...
Wavelet transformation is widely used for image de-noising. In this article an improvement of image de-noising algorithm by authority of Zhang and Salary is presented [1]. Method proposed in this paper performs image de-noising by a properly trained artificial neural networks (ANN) in wavelet domain. For better quality of de-noising, multi-scale wavelet edge detection was used.
Virtual cultural heritage research in Bosnia and Herzegovina results with a number of virtual reconstructions and virtual museums (VM). Virtual Museums are online multimedia applications using various digital content and implementation technologies. This paper presents an overview of these technologies used in our projects and their efficiency from the user's point of view.
This work addresses the twin issues of overlapping and blocking artifacts in Distributed Video Coding side information (SI). These both emanate from the block matching algorithm (BMA) used for motion vector (MV) generation rather than pixel-wise processing. In temporal correlation exploitation and particularly in the formulation of higher-order piecewise temporal trajectory interpolation (HOPTTI),...
Background subtraction involves processing of a video sequence from a static camera to detect the foreground objects in all frames. This paper introduces a robust background subtraction technique, the Adaptive Local Threshold (ALT) algorithm, which it is based on the Approximate Median Filter (AMF). It has been applied to accurately extract the moving vehicles on complex weather traffic videos (i...
This paper presents speaker gender classification and segmentation. Such classification is frequently used in broadcast news domain. Because pitch is a feature that is difficult to calculate reliably in noisy environment, and because telephone speech is present in broadcast material, we focused on using general acoustic features for gender discrimination task. We also averaged the feature values to...
A method for digital image restoration, based on the algorithm of Lagrange multipliers, has many practical applications. We apply the method to remove blur in an image caused by uniform linear motion. This method assumes that linear motion corresponds to an integral number of pixels. Compared to other classical methods, this method attains a higher value of the Improvement in Signal to Noise Ration...
Nowadays where IP telephony and multimedia applications infiltrate our daily lives the comprehension of contributing services and protocols is essential for ITK technicians and engineers. Also new added functionalities are essential. Therefore we constructed a platform for multimedia applications prototyping based on IP technology and IP phones. Our educational IP telephony platform enables students...
