Theoretical Model of the Coding Error in MCWT Video Coders
In motion-compensated wavelet based video coders (MCWT), it is known that a precise motion estimation is necessary to minimize the wavelet coefficients energy. However, a motion v...

Broadcast Channels with Delayed Finite-Rate Feedback: Predict or Observe?
Most multiuser precoding techniques require accurate transmitter channel state information (CSIT) to maintain orthogonality between the users. Such techniques have proven quite fr...

A Novel Two-Stage Rate Control Scheme for H.264
— A new rate control algorithm for the H.264 encoder is developed in this work. There are several unique features in the proposed rate control scheme. First, a two-stage encoding...

Wave Haptics: Building Stiff Controllers from the Natural Motor Dynamics
— Haptics, like the fields of robotics and motion control, relies on high stiffness position control of electric motors. Traditionally DC motors are driven by current amplifier...

Joint source-channel rate control for pixel-domain distributed video coding
We study the scenario of pixel-domain distributed video coding for noisy transmission environments and propose a method to allocate the available rate between source coding and ch...
