This paper describes a new color segmentation based on a normalized RGB chromaticity diagram for face detection. Face skin is extracted from color images using a coarse skin region with fixed boundaries followed by a fine skin region with variable boundaries. Two newly developed histograms that have prominent peaks of skin color and nonskin colors are employed to adjust the boundaries of the sk...

The subset of yij relevant to computing the correction term are those strictly bounded by the axes (see diagram Fig.1(a)). The differential equation for a variable referring to a given point on this diagram will involve the variable itself, the variable for the point diagonally down and right (via δ and β), and the variable associated with the point vertically above (via ν) see diagram Fig.1(b)...

In this paper, we present a variable bit rate control method for speech/audio coding, under the constraint that the total bit rate of a super-frame to be a constant. The proposed method uses a trellis diagram for optimizing the overall quality of the super-frame. In order to reduce the computational complexity, the trellis diagram uses approximation by ignoring the encoder memory state between ...

A variable selection procedure in regression analysis using a normalized entropy measure was firstly proposed 1996, by Amos Golan, George Judge and Douglas Miller, the book Maximum Entropy Econometrics – Robust Estimation with Limited Data. To best of authors’ knowledge, idea has not been explored literature since then, despite many noteworthy advantages that have pointed out Golan coauthors, s...

one of the most intensive occurrences of magmatism in iran was in the middle jurassic period. among the granitoid intrusions in this period as discrete bodies or complexes can be pointed to aligoodarz, alvand, astaneh, boroujerd, malayer, and chah-dozdan in the sanandaj-sirjan zone; shir-kuh and ayrakan in the central iran zone; shah-kuh, sorkh-kuh and kalateh-ahani in the lut block. these gran...
