Figure 1: L 0 smoothing accomplished by global small-magnitude gradient removal. Our method suppresses low-amplitude details. Meanwhile it globally retains and sharpens salient edges. Even the high-contrast thin edges on the tower are preserved. Abstract We present a new image editing method, particularly effective for sharpening major edges by increasing(More)
Keywords: Smart grid Power communications Communication networks Communication protocols Grid standards a b s t r a c t The next-generation electric power systems (smart grid) are studied intensively as a promising solution for energy crisis. One important feature of the smart grid is the integration of high-speed, reliable and secure data communication(More)
A rising horizon in chip fabrication is the 3D integration technology. It stacks two or more dies vertically with a dense, high-speed interface to increase the device density and reduce the delay of interconnects significantly across the dies. However, a major challenge in 3D technology is the increased power density, which gives rise to the concern of heat(More)
Interconnection plays an important role in performance and power of CMP designs using deep sub-micron technology. The network-on-chip (NoCs) has been proposed as a scalable and high-bandwidth fabric for interconnect design. The advent of the 3D technology has provided further opportunity to reduce on-chip communication delay. However, the design of the 3D(More)
We show that motion blur in successive video frames is invertible even if the point-spread function (PSF) due to motion smear in a single photo is non-invertible. Blurred photos exhibit nulls (zeros) in the frequency transform of the PSF, leading to an ill-posed deconvolution. Hardware solutions to avoid this require specialized devices such as the coded(More)
In this paper we propose a preliminary framework for accounting for certain surface F 0 variations in speech. The framework consists of definitions for pitch targets and rules of their implementation. Pitch targets are defined as the smallest operable units associated with linguistically functional pitch units, and they are comparable to segmental phones.(More)
How fast speakers can change pitch voluntarily is potentially an important articulatory constraint for speech production. Previous attempts at assessing the maximum speed of pitch change have helped improve understanding of certain aspects of pitch production in speech. However, since only "response time"--time needed to complete the middle 75% of a pitch(More)
