IMAGE SMOOTHINGWITH MINIMAL DISTORTION
"... An innovative method that enhances detail in digital images by smoothing image pixels while introducing minimal distortion is described and tested. In particular, a 14 by 14 pixel region of a digital image is smoothed using a constrained Gaussian radial basis function method. This method centers on ..."

On Minimizing Distortion and Relative Entropy
"... Abstract—A common approach for estimating a probability mass function when given a prior and moment constraints given by is to minimize the relative entropy between and subject to the set of linear constraints. In such cases, the solution is known to have exponential form. We consider the case in wh ..."

Optimizing BitByBit Power for Minimal Distortion
, 2003
"... When transmitting a sampled signal digitally, an alternative to fixed power/bit is vary the power allocated to each bit to minimize signal distortion. We adjust the power here by allowing each bit interval's duration, whether a data bit or an errorcorrection bit, to vary and seek the set of ..."

1 Minimal Distortion Principle for Blind Source Separation
"... Abstract: Blind source separation (BSS) is a method for recovering a set of source signals from the observation of their mixtures without any prior knowledge about the mixing process. In BSS the definition of a source signal has an inherent indeterminacy; any linear transform of a source signal can ..."

Minimizing Distortion For MultiPath Video Streaming
 International Conference on Image Processing, Singapore

"... We present a video distortion model analyzing the performance of multipath routing for low latency video streaming, in congestionlimited ad hoc networks. In such environments, a single node transmitting multimedia data may have an impact on the overall network conditions and may need to limit its ..."

Abstract—The expected increase in the penetration of renewables in the approaching decade urges the electricity market to introduce new products in particular, flexible ramping products to accommodate the renewables ’ variability and intermittency. CAISO and MISO are leading the design of the new ..."

Both theoretical analysis and simulation results suggest that smartly selecting the parameters may substantially reduce the distortion cost. We believe our
Minimal Distortion Morphs Generated by TimeDependent Vector Fields
, 2008
"... A morph between two Riemannian nmanifolds is an isotopy between them together with the set of all intermediate manifolds equipped with Riemannian metrics. We propose measures of the distortion produced by some classes of morphs and diffeomorphisms between two isotopic Riemannian nmanifolds and, wi ..."

In particular, we consider the class of timedependent vector fields (on an open subset Ω of R n+1 in which the manifolds are embedded) that generate morphs between two manifolds M and N via an evolution
