This paper presents a novel VQ structure which provides very good quality encoding for video sequences and exploits the computational savings gained from a fast-search algorithm. It uses an adaptive-search, variable-length encoding method which allows for very fast matching of a wide range of transmission rates. Both the encoding quality and the computational benefits from the fast-search algorithm are presented. Simulations show that full-search tree residual VQ (FTRVQ) can provide up to 3 dB improvement over a similar RVQ encoder on video sequences.

We describe a method of using a Lagrange multiplier to make a locally optimal trade off between rate and distortion in the motion search for video sequences, while maintaining a constant bit rate channel. Simulation of this method shows that it gives up to 3.5 dB PSNR improvement in a high motion sequence. A locally rate-distortion (R-D) optimal mode selection mechanism is also described. This method also gives significant quality benefit over the nominal method. Though the benefit of these techniques is significant when used separately, when the optimal mode selection is combined with the R-D optimal motion search, it …
Water And Land Use Planning For Some State Lands Near Moab, Utah, Eugene K. Israelsen, Lynn H. Davis
Water And Land Use Planning For Some State Lands Near Moab, Utah, Eugene K. Israelsen, Lynn H. Davis
Reports
In an attempt to apply better management principles to the control of state lands, the Division of State Lands asked for the study of two questions concerning state administered lands near Moab, Utah. The first question deals with the Moab and Spanish Valleys while the second question applies to Castle Valley some 10 miles northeast of Moab. The Mill Creek Development Project is proposed to provide additional water for agriculture and M & I use in the Moab and Spanish Valleys. The question for consideration is, "How much water from the Mill Creek Development Project Reservoir should the Division of …
