Speeding up video encoding process is an important issue nowadays due to the high demand of increasing the video transmission speed for real-time video applications. Many algorithms and hardware implementations have been proposed for achieving such demand using pixel domain motion estimation. Moreover, much savings in computations and hardware complexity can be achieved using frequency domain motion...
A Fast Diamond Search (FDS) algorithm based on the conventional Diamond Search (DS) algorithm is proposed. Two computationally efficient algorithms are applied to the conventional DS in order to reduce the computations with an acceptable degradation in the coding efficiency. The first algorithm is the Internal Stop Search (ISS) that is used to reduce the internal redundant SAD (Sum of Absolute Difference)...
Cloud Computing becomes the next generation architecture of IT Enterprise. In contrast to traditional solutions, Cloud computing moves the application software and databases to the large data centers, where the management of the data and services may not be fully trustworthy. This unique feature, however, raises many new security challenges which have not been well understood. In cloud computing,...
Cloud computing becomes the next generation architecture of IT Enterprise. Clouds are massively complex systems. They can be reduced to simple primitives, that are replicated thousands of times, and common functional units. The complexity of cloud computing create many issues related to security as well as all aspects of Cloud computing. One of the most important issues is data security. Clouds typically...
Motion Estimation (ME) consumes up to 70% of the entire video encoder's computations and is, therefore, the main encoding-time consuming process. Using DCT along with Adaptive Padding (AP) in frequency domain are the recently evolved Frequency Domain ME (FDME) techniques that efficiently reduce the ME computational complexity. There are two main problems of using such conventional AP in the frequency...
