In this paper, Further Reduced Resolution Depth Coding (FRRDC) method is proposed as an improvement for the Reduced Resolution Depth Coding (RRDC) method that was used for Scalable Video Coding (SVC). Similar to RRDC, FRRDC is applied by using Down-Sampling and Up-Sampling (DSUS) of the depth data of the stereoscopic 3D video. The depth data is down-sampled before the SVC encoding and up-sampled after...
Malaysia has been recognized as one of the twelve nations endowed with rich biodiversity. Such huge number of species in the rain forest and sea are an important asset that need to be properly documented. Responding to these important needs, we have designed and evaluated a content based image retrieval system catered for marine life images. This paper investigates the effectiveness of various low...
Digital image watermarking is frequently used for many purposes, such as image authentication, fingerprinting, copyright protection, and tamper proofing. Imperceptibility and robustness are the watermark requirements of good watermarks. In this paper, we propose the Fast Walsh Hadamard transform (FWHT) combined with the Discrete Cosine Transform (DCT) as a new image watermarking scheme. The FWHT reorders...
Distribution of multimedia content through the internet has gain popularity with the advancement of multimedia technology through software application with different transmission capabilities. Current conventional system implementation works perfectly for a guaranteed network bandwidth. However, when the packet experience losses due to drop in bandwidth, it could not preserve an acceptable video quality...
Abstract This study presents an effective and robust time integration procedure for general anisotropic, thermal rheologically simple viscoelasticity, that is suitable for implementation in a broad spectrum of general purpose nonlinear finite element programs. It features a judicious choice of state variables which record the extent of inelastic flow (creep), a stable backward Euler integration step,...
A nonlinear transient heat transfer finite element model is developed to simulate the curing process of polymer matrix composites. Temperature distributions inside laminates can be evaluated by solving the nonlinear anisotropic heat conduction equations including internal heat generation produced by exothermic chemical reactions. Thermal properties are assumed to be both temperature and degree of...
