DFD have to be transmitted to the receiver, a well designed video coder should balance the bits used in these two A new motion field representation based on the boundarycontrol vector (BCV) scheme for video coding is examined in parts. Other factors of consideration in video coder design this work. With this scheme, the motion field is characterized include computational cost, hardware complexi...

—A concept for variable block-size transform coding is presented. It is called adaptive block-size transforms (ABT) and was proposed for coding of high resolution and interlaced video in the emerging video coding standard H.264/AVC. The basic idea of inter ABT is to align the block size used for transform coding of the prediction error to the block size used for motion compensation. Intra ABT e...

Majid Foodeei 1;2 and Eric Dubois 2;1 Abstract | In this contribution an entropy-constrained code-excited linear predictive quantizer (EC-CELP) is introduced. EC-CELP addresses the problems associated with high quality, low delay, low complexity, low bit rate source coding of sources with memory. The motivation comes from the applications in motion-compensated time varying image compression. As...

Proficient Content Based Image Retrieval system is a much needed system for plenty of image retrieval supporting applications, which retrieve images more rapidly from giant image databases. Block Truncation Coding (BTC) is one of the prominent and simple techniques used most of the time. This method is built on color properties of an image for image retrieval. In this paper a novel Static Thepa...

Arbitrary shaped coding is an important issue of MPEG-4. In this study, an efficient shaped coding method, called the boundary block-searching (BBS) algorithm that can enhance the coding efficiency of conventional padding schemes, is proposed. The proposed BBS algorithm assumes that boundary blocks have strong correlation even though they are not connected. For an input boundary block, the most...

We introduce the Markov Stochastic Block Model (MSBM): a growth model for community based networks where node attributes are assigned through Markovian dynamic. rely on HMMs’ literature to design prediction methods that robust local clustering errors. focus specifically link and collaborative filtering problems we new selection procedure infer number of hidden clusters in network. Our approache...

Abstract The development of computational thinking skills is attracting attention worldwide. use visual or block-based coding in primary schools has gained momentum. Yet, students' acceptance such environments been neglected the literature. This study presents a measurement instrument that will allow pursuing an endeavor. Technology Acceptance Model was used as guiding framework. A panel eight ...
