Variable transform block (TB) sizes cause high computational complexity at the HEVC encoder. In this paper, a fast residual quad-tree (RQT) structure decision method is proposed to reduce the number of candidate transform sizes. The proposed method uses spatial and temporal correlation information in the neighbor blocks to predict the depth of current RQT. In addition, an efficient all zero block...
Measurement uncertainty provides a quantitative reference to choose appropriate instruments and measurement methods. This paper focuses on the measurement uncertainty introduced by measurement instruments in frequency domain channel measurement systems. For frequency domain channel measurement, the measurement instrument, Vector Network Analyzer, need to be calibrated before measurement. The uncertainty...
This paper investigates the measurement uncertainty introduced by measurement instruments in frequency domain channel measurement systems. The uncertainty is a quantitative indication of the quality of the measurement results, so it provides a quantitative reference to chose appropriate instruments and measurement methods. The uncertainty analysis is based on Monte Carlo method. To account for the...
Background Mannitol and hypertonic saline are used to ameliorate brain edema and intracranial hypertension during and after craniotomy. We hypothesized that the agreement of measured and calculated serum osmolality during the infusion of hypertonic saline would be better than mannitol. The objective was to determine the accuracy of serum osmolality estimation by different formulas during the administration...
The band selection of multispectral remote sensing image is a key issue and hot topic in remote sensing image processing domain. Considering that the band selection results of methods are usually not satisfying, a novel remote sensing image band selection method based on independent component analysis is proposed in this paper. The proposed method determine the number of independent components according...
This paper proposes a new text categorization method based on the similar rough set and the fuzzy cognitive map (FCM). The method replaces casual relation with correlation relation in the fuzzy cognitive map, called correlation-FCM, for constructing text classifiers. Text categorization can be implemented by reasoning approaches based on fuzzy cognitive maps which include weights and correlation degrees...
