Dynamic macroblock wavefront parallelism for parallel video coding
Journal of Visual Communication and Image Representation, 2015Detail performance analysis of the traditional macroblock row wavefront (MRW) parallelism.A new dynamic macroblock wavefront (DMW) parallelism.An efficient implementation of video encoder with DMW. Wavefront parallelism is effective for parallel video encoding thanks to its merits of low latency, no quality loss and high degree of parallelism.

Joint fractional Fourier analysis of wavefront-coding systems
Optics Letters, 2009The analysis of wavefront-coding systems is explored via the joint fractional Fourier signal representation (JFF) of the pupil function. The properties of the JFF of the pupil function are presented and are shown to be revealing with regard to the system response to defocus. Numerical examples that illustrate the properties are given.

Coded Shack-Hartmann Wavefront Sensor
2016Wavefront sensing is an old yet fundamental problem in adaptive optics. Traditional wavefront sensors are limited to time-consuming measurements, complicated and expensive setup, or low theoretically achievable resolution. In this thesis, we introduce an optically encoded and computationally decodable novel approach to the wavefront sensing problem ...

Wavefront Coded Imaging Systems for MEMS Analysis
International Symposium for Testing and Failure Analysis, 2002Abstract A new imaging technique called Wavefront Coding allows real-time imaging of three-dimensional structures over a very large depth. Wavefront Coding systems combine aspheric optics and signal processing to achieve depth of fields ten or more times greater than that possible with traditional imaging systems.
