The aim of this study is to establish cephalometric norms using Jarabak's analysis for an Iraqi community sample and to compare these norms with the norms used by Jarabak's analysis. In this study mean values of Jarabak's cephalometric analysis for Iraqi was determined. There are no previous studies establishing cephalometric norms for Iraqi population according to Jarabak's analysis and there are no previous studies published about Cephalic Index (CI) of Iraqi community.the present study identified the shape of the head for Iraqi community.The mean cephalic indices in Iraqi male and female were found to be 79.45 And 74.34 respectively, the shape of the head for Iraqi community is distinguished as Mesocephalic.The mean of Facial Proportion are significantly much less in Iraqi community (55.38% ) compared with Saudi community(64.65%),and also was significantly much less compared with Jarabak's norms (63.5%).The numbers of cases used in this study were 100 for females and 120 for males of young adults; the ages were between 18-32 years. The results of this study will be of importance in forensic medicine, anthropology and in genetics.The present study, the cephalic algorithm, was conducted through application c++ programming.

“…In this approach, only one halftoned color-quantized image is stored. To obtain a halftoned color-quantized image of smaller size, the available halftoned color-quantized image is first restored to its original [8], [9] or low-pass filtered to remove the high-frequency noise. The processed image is then downscaled and color quantized again to produce the image of desirable resolution.…”

Abstract-To reliably and efficiently deliver media information to diverse clients over heterogeneous networks, the media involved must be scalable. In this paper, a color quantization algorithm for generating scalable colorindexed images is proposed based on a multiscale error diffusion framework. Images of lower resolutions are embedded in the outputs such that a simple down-sampling process can extract images of any desirable resolutions. Images possessing this scalable property support transmission over the Internet which contains clients with different display resolutions, systems with different caching resources and networks with varying bandwidths and QoS capabilities. Unlike most of the color halftoning algorithms available nowadays, the proposed algorithm is not dedicated for printing applications but for color-indexed displays. It works with any arbitrary palettes of different size.Index Terms-Color index, color quantization, directional hysteresis, error diffusion, halftoning, multiscale processing, scalable media.
