This paper presents the intra prediction and mode coding of Versatile Video Coding (VVC) standard. standard was collaboratively developed by Joint Experts Team (JVET). It follows traditional architecture a hybrid block-based codec that also basis previous standards. Almost all features VVC either contain substantial modifications in comparison with its predecessor H.265/HEVC or were newly added...

Researchers have, in recent times, achieved excellent compression efficiency by implementing a more complicated algorithm due to the rapid development of video compression. As result, next model compression, High-Efficiency Video Coding (HEVC), provides high-quality output while requiring less bandwidth. However, intra-prediction technique HEVC requires significant processing complexity. This r...

HIGH PROFILE Tzu-Der Chuang, Yi-Hau Chen, Chen-Han Tsai, Yu-Jen Chen, and Liang-Gee Chen DSP/IC Design Lab., Graduate Institute of Electronics Engineering, National Taiwan University, Taipei, Taiwan Email: {peterchuang, ttchen, phenom, yjchen, lgchen}@video.ee.ntu.edu.tw ABSTRACT In this paper, we propose a novel two-stage intra prediction algorithm and hardware architecture that can support H....

This paper addresses the problem of converting intra coded video from H.264 to MPEG-2. Since these two coded formats have fundamental differences in regard to their transform block sizes and intra prediction modes, conversion between them is a challenging task. A fast frequency domain conversion method is proposed to convert the integer transform (IT) coefficients into discrete cosine transform...

introduction: doing chest x ray (cxr) for all trauma patients is not efficient and cost effective due to its low diagnostic value. the present study was designed aiming to evaluate the diagnostic accuracy of thoracic injury rule out criteria (tirc) in prediction of traumatic intra-thoracic injuries and need for cxr.  method: the present study is a prospective cross-sectional study that has been...

Intra-prediction is amethod for coding standalone frames in video coding. Until now, this hasmainly been done using linear formulae. Using an Artificial Neural Network (ANN)may improve the prediction accuracy, leading to improved coding efficiency. In this degree project, Fully Connected Networks (FCN) and Convolutional Neural Networks (CNN) were used for intra-prediction. Experiments were done...

BACKGROUND/AIMS Narrow band imaging (NBI) endoscopy can be used for gross differentiation between the types of colonic polyps. This study was conducted as a retrospective study for estimation of the interobserver and intra-observer agreement of the pit pattern of the mucosal surface and the accuracy of histology prediction. METHODS A total of 159 patients underwent complete colonoscopy and 21...
