Multirate 3-D subband coding of video
We propose a full color video compression strategy, based on 3-D subband coding with camera pan compensation, to generate a single embedded bit stream supporting multiple decoder display formats and
Fast optical and process proximity correction algorithms for integrated circuit manufacturing
TLDR
The key contributions to the OPC field made in this thesis work include formulation of OPC as a feedback control problem using an iterative solution, and use of fast aerial image simulation for OPC, which truly enables full chip model-based OPC.
Iterative procedures for reduction of blocking effects in transform image coding
  • A. Zakhor

    IEEE Trans. Circuits Syst. Video Technol.
  • 1 March 1992
TLDR
An iterative block reduction technique based on the theory of a projection onto convex sets to impose a number of constraints on the coded image in such a way to restore it to its original artifact-free form.
Very low bit-rate video coding based on matching pursuits
TLDR
A matching-pursuit based motion residual coder which uses an inner-product search to decompose motion residual signals on an overcomplete dictionary of separable Gabor functions, providing detailed reconstructions without block artifacts.

  • 10 December 2002
TLDR
The video signature method is developed as a technique to summarize video efficiently for visual similarity measurements and it is demonstrated that this measure is well approximated by the volume of the intersection between Voronoi cells of similar clusters.
An optimization approach for removing blocking effects in transform coding
TLDR
The authors propose a new approach for reducing the blocking effect which can be applied to conventional transform coding without introducing additional information or significant blurring, and is based on the gradient projection method.

Multiple sender distributed video streaming
TLDR
This work proposes a receiver-driven protocol for simultaneous video streaming from multiple senders to a single receiver in order to achieve higher throughput, and to increase tolerance to packet loss and delay due to network congestion.
Real-Time Internet Video Using Error Resilient Scalable Compression and TCP-Friendly Transport Protocol
We introduce a point to point real-time video transmission scheme over the Internet combining a low-delay TCP-friendly transport protocol in conjunction with a novel compression method that is error
