Robust face recognition under various illumination environments is very difficult and needs to be accomplished for successful commercialization. In this paper, we propose an improved illumination normalization method for face recognition. Illumination normalization algorithm based on anisotropic smoothing is well known to be effective among illumination normalization methods but deteriorates th...

The adsorption behaviour of N20 on the Si(001)2 × ! surface at 300 K substrate temperature has been investigated by measuring in situ the surface conductance during the reaction process. For comparison we monitored in the same way the adsorption of 0 2 on the same surface which ultimately leads to the fiat band situation. The adsorption of atomic oxygen as released by decomposition of the N20 m...

In this paper, an adaptive motion vector smoothing scheme based on weighted vector median filtering is proposed in order to eliminate the motion outliers more effectively for improving the quality of side information in frame-based distributed video coding. We use a simple motion vector outlier reliability measure for each block in a motion compensated interpolated frame and apply weighted vect...

ANNARIMA that combines both autoregressive integrated moving average (ARIMA) model and artificial neural network (ANN) model is a valuable tool for modeling and forecasting nonlinear time series, yet the over-fitting problem is more likely to occur in neural network models. This paper provides a hybrid methodology that combines both radial basis function (RBF) neural network and auto regression...

Purpose This paper examines the determinants of bank income smoothing using loan loss provisions in United Kingdom or Great Britain from 1999 to 2017. Design/methodology/approach The study used ordinary least square (OLS) regression and applying HAC robust standard error correction test. Findings findings showed that UK banks use provision for purposes. Income is greater times high economic pol...

OXYGEN FAIL-SAFE SYSTEMS for anaesthetic gas machines have been advocated as standard safety features. 1-4 They are designed to prevent delivery of hypoxic gas mixtures in the event of an interruption or exhaustion of O~ pipeline or tank sources. In such a circumstance the fail-safe device causes all gas flow to cease, so alerting the operator of the apparatus to the problem. Some types of gas ...
