We present two graph-based algorithms for multiclass segmentation of high-dimensional data on graphs. The algorithms use a diffuse interface model based on the Ginzburg-Landau functional, related to total variation and graph cuts. A multiclass extension is introduced using the Gibbs simplex, with the functional s double-well potential modified to handle the multiclass case. The first algorithm minimizes the functional using a convex splitting numerical scheme. The second algorithm uses a graph...

One of the most fundamental problems in vision is segmentation; the way in which parts of an image are perceived as a meaningful whole. Recent work has shown how to calculate images of physical parameters from raw intensity data. Such images are known as intrinsic images, and examples are images of velocity (optical flow), surface orientation, occluding contour, and disparity. The principal difficulty with intrinsic images is that each by itself is generally underconstrained; they can only be...

A convenient representation for blob-like figures in an image consists of the orientation, length, and width of a bounding rectangle. One fast algorithm for producing such a bounding rectangle is based upon a dot product space. The analysis of the dot product space shape representation is improved to handle certain pathological cases, and it is shown how to generalize this analysis to accommodate different criteria for the goodness of the representation.

Brain MR image segmentation takes an important role in research and clinical application. Statistical method is effective in the segmentation, which is usually based on maximum a posterior (MAP). The key of MAP method is to estimate a prior probability of the segmentation. Multilevel logistic (MLL) model has been used in practice for the estimation. To farther improve the performance of the segmentation, a weighted MLL (WMLL) model is proposed in this paper. The simulated results show that the...

This report presents an abstract process model of 'well formed' discourse. The model is based on a hierarchical segmentation of utterances into distinct, but related and linked, context spaces. Context spaces are characterized by slots similar to case frames. The slots are functionally defined and they capture information both explicit and implicit in the dialogue. In a context space theory of discourse, a conversation is viewed as a sequence of conversational moves. A conversational move...

The primary goal of this research is to test the effectiveness of various image processing techniques applied to acoustic images generated in MATLAB. The simulated acoustic images have the same characteristics as those generated by a computer model of a high resolution imaging sonar. Edge Detection and Segmentation are the two image processing techniques discussed in this study. The two methods tested are a modified version of the Kalman filtering and median filtering.

Many computer vision problems can be formulated as computing the minimum energy states of thermal dynamic systems. However, due to the complexity of the energy functions, the solutions to the minimization problem are very difficult to acquire in practice. Stochastic and deterministic methods exist to approximate the solutions, but they fail to be both efficient and robust. This paper describes a new deterministic method--the Highest Confidence First algorithm--to approximate the minimum energy...

Experiments have been performed with the electron beam at the NRL linac in which confined explosives were partially irradiated to study how the reaction spreads radially from the hot central region to the cool outer regions. Four types of high explosives were studied: PBX-9404, PBXW-109, HBX-1, and TATB. Data were obtained with two sets of beam pulse parameters, and as a function of confinement window thickness. The results vary widely, from no reaction spreading at all in TATB to complete...

Slow spreading ridges are composed of ridge segments, which are fundamental units of magmatic accretion and tectonic deformation. The objective of this thesis is to characterize these tectonic processes, identify factors controlling segment propagation, and constrain lithospheric strength with deformation experiments.

A method for modeling images of natural terrain is developed and applied to the segmentation of aerial photographic data. An underlying stochastic structure based on linear filtering concepts provides a means of modeling the terrain in local areas of the image. Superimposed on this is a Markov random field that describes transitions from regions of one terrain type to another. Maximum likelihood and maximum a posteriori estimation is applied to estimate regions of similar terrain. Results of...

It shows that a robotic platform can build up and maintain a system for object localization, segmentation, and recognition, starting from very little. What the robot starts with is a direct solution to achieving figure/ground separation: it simply 'pokes...

In this paper, we propose an efficient multiscale approach for the segmentation of natural clutter, specifically grass and forest, in synthetic aperture radar (SAR) imagery. This method exploits the coherent nature of SAR sensors. In particular, we exploit the characteristic statistical differences in imagery of different clutter types, as a function of scale, due to radar speckle. We employ a recently introduced class of multiscale stochastic processes that provide a powerful framework for...

First, to automatically select the SM that best represents the object, and second, to accurately segment the image taking into account both the image...

Influencing one's adversary has always been an objective in warfare. However, to date the majority of influence operations have been geared toward the masses or to very small numbers of individuals. Although marginally effective, this approach is inadequate with respect to larger numbers of high value targets and to specific subsets of the population. Limited human resources have prevented a more tailored approach, which would focus on segmentation, because individual targeting demands...
