A Transformation System for Developing Recursive Programs
, 1977
"... A system of rules for transforming programs is described, with the programs in the form of recursion equations An initially very simple, lucid. and hopefully correct program IS transformed into a more efficient one by altering the recursion structure Illustrative examples of program transformations ..."

Where are the really hard manipulation problems? The manipulation phase transition
"... Voting is a simple mechanism to aggregate the preferences of agents. Many voting rules have been shown to be NP-hard to manipulate. However, a number of recent theoretical results have suggested that this complexity may only be in the worst-case and manipulation may be easy in practice. In this pape ..."

A Nonlinear Primal-Dual Method For Total Variation-Based Image Restoration
, 1995
"... . We present a new method for solving total variation (TV) minimization problems in image restoration. The main idea is to remove some of the singularity caused by the non-differentiability of the quantity jruj in the definition of the TV-norm before we apply a linearization technique such as Newton ..."

norms. Experimental results show that the new method has much improved global convergence behaviour than the primal Newton's method. 1. Introduction. During some phases of the manipulation of an image some random noise and blurring is usually introduced. The presence of this noise and blurring
A shape-based approach to the segmentation of medical imagery using level sets
- IEEE Trans. Med. Imag
, 2003
"... Abstract—We propose a shape-based approach to curve evolution for the segmentation of medical images containing known object types. In particular, motivated by the work of Leventon, Grimson, and Faugeras [15], we derive a parametric model for an implicit representation of the segmenting curve by app ..."

by applying principal component analysis to a collection of signed distance representations of the training data. The parameters of this representation are then manipulated to minimize an objective function for segmentation. The resulting algorithm is able to handle multidimensional data, can deal
The MPEG-4 video standard verification model
- IEEE Trans. Circuits and Syst. Video Techonol
, 1997
"... Abstract—The MPEG-4 standardization phase has the man-date to develop algorithms for audio-visual coding allowing for interactivity, high compression, and/or universal accessibility and portability of audio and video content. In addition to the conven-tional “frame”-based functionalities of the MPEG ..."

Integrating gesture recognition and direct manipulation
- In Proceedings of the Summer '91 USENIX Technical Conference
, 1991
"... CMU-ITC-91 i00 A gesture-based interface is one in which the user specifies commands by simple drawings, typically made with a mouse or stylus. A single intuitive gesture can simultaneously specify objects, an operation, and additional parameters, making gestures more powerful than the "cli ..."

interface. More interestingly, GRANDMA supports a new two-phase interaction technique, in which a gesture collection phase is immediately followed by a manipulation phase. In its simplest form, the phase transition is indicated by keeping the mouse still while continuing to hold the button down
The Manipulated Consensus:

Deformable Linear Object manipulation planning with contacts
"... Abstract—We consider the manipulation planning problem of a Deformable Linear Object (DLO) in free or contact space. We assume the DLO is handled by a gripper at one of its extremities and during the manipulating phase, the grasped end may change. The problem is solved by coupling dynamic simulation ..."

Learning to Predict Phases of Manipulation Tasks as Hidden States
"... Abstract—Phase transitions in manipulation tasks often oc-cur when contacts between objects are made or broken. A switch of the phase can result in the robot’s actions suddenly influencing different aspects of its environment. Therefore, the boundaries between phases often correspond to constraints ..."
