[ 1 ] - A Fast Block Size Decision For Intra Coding in HEVC Standard
Intra coding in High efficiency video coding (HEVC) can significantly improve the compression efficiency using 35 intra-prediction modes for 2N×2N (N is an integer number ranging from six to two) luma blocks. To find the luma block with the minimum rate-distortion, it must perform 11932 different rate-distortion cost calculations. Although this approach improves coding efficiency compared to the …
[ 2 ] - Fast Intra Mode Decision for Depth Map coding in 3D-HEVC Standard
three dimensional- high efficiency video coding (3D-HEVC) is the expanded version of the latest video compression standard, namely high efficiency video coding (HEVC), which is used to compress 3D videos. 3D videos include texture video and depth map. Since the statistical characteristics of depth maps are different from those of texture videos, new tools have been added to the HEVC standard for …

[ 4 ] - Compressed Domain Scene Change Detection Based on Transform Units Distribution in High Efficiency Video Coding Standard
Scene change detection plays an important role in a number of video applications, including video indexing, searching, browsing, semantic features extraction, and, in general, pre-processing and post-processing operations. Several scene change detection methods have been proposed in different coding standards. Most of them use fixed thresholds for the similarity metrics to determine if there was …
[ 5 ] - پیش‌بینی بقاء بیماران مبتلا به سرطان ریه با استفاده از سیستم استنتاج عصبی- فازی تطبیقی بهبودیافته
مقدمه: سرطان ریه منبع اصلی مرگ‌ومیر برای مردان و زنان در سراسر جهان می‌باشد. بیماری ریه توسعه و رشد غیرقابل‌کنترل سلول‌ها در یک یا هر دو ریه می‌باشد. تشخیص زودرس سرطان آسان نیست؛ اما اگر سریع تشخیص داده شود، قابل‌درمان است. هدف از این مطالعه، ساخت مدل بهینه پیش‌بینی کننده بقاء بیماران مبتلابه سرطان ریه بر اساس ویژگی‌های بیماران با رویکرد داده‌کاوی می‌باشد. روش: در این مطالعه توصیفی- کاربردی، از ا…
[ 6 ] - Predicting Survival of Patients with Lung Cancer Using Improved Adaptive Neuro-Fuzzy Inference System
Introduction: Lung cancer is the main cause of mortality in both genders worldwide. This disease is caused by the uncontrollable growth and development of cells in both or one of the lungs. Although the early diagnosis of this cancer is not an easy task, the earlier it is diagnosed, the higher will be the chance of treating. The objective of this study was to develop an optimized prediction model…
