Intelligent Scissors for Image Composition
- In Computer Graphics, SIGGRAPH Proceedings
, 1995
"... We present a new, interactive tool called Intelligent Scissors which we use for image segmentation and composition. Fully automated segmentation is an unsolved problem, while manual tracing is inaccurate and laboriously unacceptable. However, Intelligent Scissors allow objects within digital images ..."

, rather than simply the strongest edge in the neighborhood. Boundary cooling automatically freezes unchanging segments and automates input of additional seed points. Cooling also allows the user to be much more free with the gesture path, thereby increasing the efficiency and finesse with which boundaries
Interactive segmentation with intelligent scissors

"... M any organizational blueprints have beensubmitted as the basis for restructuring the United Stateshealth system, but only three basic models have a reasonable chance of being implemented: (1) the Professional Model, the name I have applied to the existing American health system, (2) the Central Pla ..."

in recent months. Yet no one can say for certain what a truly competitive health market would be like, because in no instance do HMOs command a large enough segment of the health market to make their competitive influence felt. In a general way, the effectiveness of these models can be compared simply
Back to the Beginning: Persistence and the Cross-Section of Corporate Capital Structure, The Journal of Finance, forthcoming
"... We examine the dynamic behavior of corporate capital structures in order to determine the empirical relevance of recent theories. We begin by showing that capital structure is highly persistent, so much so that the cross-sectional distribution of leverage in the year prior to the IPO is largely unch ..."

unchanged almost twenty years later. Moreover, our analysis suggests that market timing (Baker and Wurgler (2002)) and inertia (Welch (2004)) are unlikely explanations for the observed cross-sectional variation in capital structures, which exists prior to firms ’ IPOs. Rather, our results indicate
Brief Segments
, 1991
"... While the tones of Mandarin are conveyed mainly by the Fa contour, they also differ consistently in duration and in ampli-tude contour. The contribution of these factors was examined by using signal-correlated noise stimuli, in which natural speech is manipulated so that it has no Fa or formant stru ..."

Partly Supervised Uighur Morpheme Segmentation
"... Abstract. This paper introduces Uighur morpheme segmentation, which is a basic part of the comprehensive effort of the Uighur language corpus compilation, conducted at Xinjiang University in cooperation with Kyoto University. Uighur is an agglutinative language with word structures formed by product ..."

REGION-LEVEL MOVING OBJECT SEGMENTATION BY GRAPH LABELING
"... In this paper we propose a method for the detection and localization of moving objects. The change detection problem in the pixel domain is formulated by two zero mean Laplacian distributions. Furthermore, the image is split in homogeneous colour regions and their inter-frame mean absolute differenc ..."
Abstract

difference is used to describe the change detection problem in the region level by two Gamma distributions. The pixel and region based change detection statistics are used to classify the colour regions as “changed ” or “unchanged” with high confidence. These initially labeled regions constitute the “seeds
Segmentation-based regularization of dynamic SPECT reconstructions
- in IEEE Medical Imaging / Nuclear Science Conference, 2009
"... Abstract-Dynamic SPECT reconstruction using a single slow camera rotation is a highly underdetermined problem, which requires the use of regularization techniques to obtain useful results. The dSPECT algorithm We test this approach with a digital phantom simulating the kinetics of Tc99m-DTPA in th ..."

Furthermore, in two cases where the segmentation was intentionally done incorrectly, the spatially regularized reconstructions were still as good as the non-regularized ones. In general, the segmentation-based regularization improves TAC quality within ROIs, as well
Segmentation decreases the magnitude of the tilt illusion
"... In the tilt illusion, the perceived orientation of a target grating depends strongly on the orientation of a surround. When the orientations of the center and surround gratings differ by a small angle, the center grating appears to tilt away from the surround orientation (repulsion), whereas for a ..."

for segmentation/perceptual grouping. For example, in three-dimensional (3-D) space, an occluding ring in front of a border between target and context would make the border ambiguous and actually encourage the grouping of the center and surround. This would leave the filtering input unchanged in the Schwartz model
SEGMENTATION AND APPEARANCE MODEL BUILDING FROM AN IMAGE SEQUENCE
"... In this paper we explore the problem of accurately segmenting a person from a video given only approximate location of that person. Unlike previous work which assumes that the appearance model is known in advance, we developed an iterative expectation-sampling (ES) algorithm for solving segmentation ..."

This appearance model remains unchanged during a short time period, although the object can articulate. Thus, we can perform the ES iteration not only for a
