A Multiplication-Free Algorithm and A Parallel Architecture for Affine Transformation

Affine transformation is widely used in image processing. Recently, it is recommended by MPEG-4 for video motion compensation. This paper presents a novel low power parallel architecture for texture warping using affine transformation (AT). The architecture uses a novel multiplication-free algorithm that employs the algebraic properties of the AT. LowRead More

A Parallel Multiplication-Free Algorithm and Architecture for Affine-based Motion Compensation

  Affine transformation is widely used in image processing. Recently, it has been recommended by MPEG-4 for video motion compensation. We present a novel low-power parallel architecture for texture warping using affine transformation (AT). The architecture uses a novel multiplication-free algorithm that employs the algebraic properties of the affine transformation.Read More

System on Chip: the Future of System Integration

System on chip: The future of the integration paradigm Syste`me sur une puce: le futur du paradigme de l’inte ́gration Wael Badawy The increase in the number of transistors that can be integrated on a single chip allows the integration of more functions. On the other hand, time-to-market pressures requireRead More

Low power very large scale integration prototype for three-dimensional discrete wavelet transform processor with medical application

We present a low-power 3-D discrete wavelet transform processor for medical applications. The main focus is the compression of medical resonance image (MRI) data, although the system could be used as a generic compression chip. The architecture eliminates redundant filter banks by using a central control unit to dynamically adjustRead More

A Low Power Architecture for HASM Motion Tracking

This paper proposes low power VLSI architecture for motion tracking that can be used in online video applications such as in MPEG and VRML. The proposed architecture uses a hierarchical adaptive structured mesh (HASM) concept that generates a content-based video representation. The developed architecture shows the significant reducing of powerRead More

A Low Power VLSI Architecture for Mesh-based Video Motion Tracking

This paper proposes a low-power very large-scale integration (VLSI) architecture for motion tracking. It uses a hierarchical adaptive structured mesh that generates a content-based video representation. The proposed mesh is a coarse-to-fine hierarchical two-dimensional mesh that is formed by recursive triangulation of the initial coarse mesh geometry. The structured meshRead More

A VLSI Architecture for Video Object Motion Estimation Using a 2D Hierarchical Mesh Model

This paper proposes a novel hierarchical mesh-based video object model and a motion estimation architecture that generates a content-based video object representation. The 2D mesh-based video object is represented using two layers: an alpha plane and a texture. The alpha plane consists of two layers: (1) a mesh layer andRead More

Applying FEA to Investigate the performance of Electrostatic Comb-Drive Actuators Utilized by on-a-chip systems

This study focuses on investigating the design parameters of lateral electrostatic comb-drive actuators, where the effect of these parameters on the actuation performance is explored using finite element analysis (FEA). This level of analysis is essential to the design process of system-on-a-chip microelectromechanical systems (MEMS) applications, where a comb driveRead More

An Optimal Call Admission and Bandwidth Reservation Scheme for Future Wireless Networks

The next generation wireless networks promises availability of a wide variety of services. To be supported successfully, it is necessary to provide quality of service (QoS) between end-systems with the resources whose cost is discouragingly high. This paper proposes a new scheme for call admission and bandwidth reservation for theRead More
