Modern hardware systems of processing the video data stream for color coding apply the principle of constant brightness proposed in the development of the NTSC color coding system. This principle, like its implementation, is not free from drawbacks: loss of information on the clarity of the encoded color images, degradation of clarity in achromatic details and images as the color saturation increases, etc. In addition, the use of video data decoding formats in digital video data processing systems, such As 4:2:2, 4:2:0, 4:1:1, distorts the decoded video image.
An alternative approach for encoding a color video stream is to apply the principle of constant color luminance. The work describes the coding according to the principle of constant color luminance. A comparative analysis of the transformed images is carried out with the help of the two principles given. The advantage of applying the principle of constant color brightness in digital video coding systems is shown. It is shown that using the principle of constant color brightness it is possible to obtain a gain of more than 6 dB.
The implementation of the principle of constant color luminance for real and integer modern hardware platforms is described. A comparative analysis of the realizations of the principles of constant brightness and constant color luminance was carried out, showing the advantage of applying the principle of constant color luminance for some modern processors.
The application of the principle of constant color luminance in digital video encoding systems can help improve the quality of recoverable color coded images.
The transformable designs of space basing are delivered into orbit in a folded state, which creates the task of their reliable disclosure. In this paper we propose to use an actuator in the form of electrical machines as the executive body. The use of this type of actuator allows controlling the process of deployment.
As a large-sized transformable structure we consider the space-based reflector. At present, the transfer of the machines from the folded state to the operation state is carried out by stages. The paper considers the joint implementation of two stages: the rotation of the root unit of the spoke and the extension of the intermediate unit. Mathematical models for rotational and translational motions are developed which take into account such parameters as bending and contraction of the spoke. Modeling and analysis of the results of different variants of the joint disclosure of the reflector elements are made: the use of the engine for each of the components of the motion and the use of centrifugal force for the extension of the spoke.
The application of the algorithm for correcting the control parameters is considered. One of the important advantages of the algorithm is the ability to carry control in real time. It can be used to calculate the reference control in algorithms based on the two-channel principle.
This paper is devoted to feature selection and evaluation in an automatic text-independent speaker verification task. In order to solve this problem a speaker verification system based on the Gaussian mixture model and the universal background model (GMM-UBM system) was used.
The application sphere and challenges of modern systems of automatic speaker identification were considered. Overview of the modern speaker recognition methods and main speech features used in speaker identification is provided. Features extraction process used in this article was examined. Reviewed speech features were used for speaker verification including mel-cepstral coefficients (MFCC), line spectral pairs (LSP), perceptual linear prediction cepstral coefficients (PLP), short-term energy, formant frequencies, fundamental frequency, voicing probability, zero crossing rate (ZCR), jitter and shimmer.
The experimental evaluation of the GMM-UBM system using different speech features was conducted on a 50 speaker set and a result is presented. Feature selection was done using the genetic algorithm and the greedy adding and deleting algorithm.
Equal error rate (EER) equals 0,579 % when using 256 component Gaussian mixture model and the obtained feature vector. Comparing to standard 14 MFCC vector, 42,1 % of EER improvement was acquired.
