This paper presents an advanced screen content coding solution using color table and index map method. It is implemented on top of the High-Efficiency Video Coding (HEVC) Range Extension (RExt) standard draft version 5 [1], fully harmonized with the HEVC recursive quad-tree structure and also one of the promising tool under investigation for emerging HEVC based screen content coding extension. For...
The task of visual vocabulary construction plays an important role in the bag-of-words based pattern analysis and robotic applications. A discriminative vocabulary generation in unsupervised case is an open issue for reducing perceptual aliasing in image matching based applications. In this paper, we present a scheme to evaluate the discriminative power of each visual word quantitatively in terms...
In this paper we present a method for identification of temporal patterns that are predictive of events in a dynamic data system. The proposed new MRPS-HMM method applies a hybrid model using Reconstructed Phase Space (RPS) and stochastic state estimation via Hidden Markov Model (HMM) to search predictive patterns. This method constructs a multivariate phase space by embedding each data sequence with...
In this paper we present a method for detecting multivariate temporal patterns that are characteristic and predictive of significant events in a multivariate dynamic data system. A new hybrid RPS-GMM method is applied to identify patterns. This method constructs phase space embedding by using individual embedding of each variable sequences. We employ discriminative approach by applying Gaussian Mixture...
RS is a popular FH code whose chaotic features of frequency sequence is analyzed in this article and such a conclusion is achieved that RS code is of chaotic features in terms of frequency sequence. According to this conclusion, a method of FH prediction about the degree of incidence is suggested based on the phase space reconstruction of chaotic system. It is more accurate than the chaos prediction...
The studies on the assessment of urban landscape river health are scarce. The aggregative indicator approach, which is commonly used currently, has the deficiencies of burying the variance among the indicators and often results in imperfect answer. An integrated assessment procedure, combining the key limiting indicators with aggregative indicators, is put forward. The aggregative indicators system...
Tabular expressions have been used in industry for many years to precisely document software in a readable notation. In this paper, we propose a fault-based testing technique that traces the propagation of faults from the expression in each cell of a tabular expression to the output of the program under test. The technique has been formalized in the form of abstract test case constraints also represented...
This paper presents a new method, called multiple temporal pattern recognition (MTPR), that is capable of detecting multiple temporal patterns for characterizing and predicting events of interest in the time-evolving system data. The MTPR method embeds time series data into multiple phase spaces with various dimensions and time delays. Then it clusters the embedded data to detect the preliminary temporal...
