Image-Based Frame Gating of IVUS Pullbacks: A Surrogate for ECG
Intravascular ultrasound (IVUS) is a catheter-based modality which is used to produce high-resolution, cross-sectional images of the interior of blood vessels. By capturing 2-D IV...

Efficient Edge-Based Methods for Estimating Manhattan Frames in Urban Imagery
We address the problem of efficiently estimating the rotation of a camera relative to the canonical 3D Cartesian frame of an urban scene, under the so-called "Manhattan World&...

Context-adaptive pixel based prediction for intra frame encoding
Intra prediction is one effective method to remove the spatial redundancies in intra frame coding. Better intra prediction will result in the residual with less energy, which will...

A Rate-Distortion Approach to Wavelet-Based Encoding of Predictive Error Frames
In this paper, we develop a framework for efficiently encoding predictive error frames (PEF) as part of a rate scalable, wavelet-based video compression algorithm. We investigate ...

An Adaptive Frame-Based Interpolation Method of Channel Estimation for Space-Time Block Codes in Moderate Fading Channels
Abstract -- The application of Orthogonal SpaceTime Block Codes (O-STBC) as the encoding scheme in the presence of "non-quasi-static" fading was considered. A simple and ...
