Solving the Chan-Vese model by a multiphase level set algorithm based on the topological derivative

1st international conference on scale space and variational methods in computer vision

In this work, we specifically solve the Chan-Vese active contour model by multiphase level set methods. We first develop a fast algorithm based on calculating the variational energy of the Chan-Vese model without the length term. We check whether the energy decreases or not when we move a point to another segmented region. Then we draw a connection between this algorithm and the topological derivative, a concept emerged from the shape optimization field. Furthermore, to include the length terra of the Chan-Vese model;we apply a preprocessing step on the image by using nonlinear diffusion. We show numerical experiments to demonstrate the efficiency and the robustness of our algorithm.

Restoration of images with piecewise space-variant blur

We address the problem of space-variant image deblurring, where different parts of the image are blurred by different blur kernels. Assuming a region-wise space variant point spread function, we first solve the problem for the case of known blur kernels and known boundaries between the different blur regions in the image. We then generalize the method to the challenging case of unknown boundaries between the blur domains. Using variational and level set techniques, the image is processed globally. The space-variant deconvolution process is stabilized by a unified common regularizer, thus preserving discontinuities between the differently restored image regions. In the case where the blurred sub-regions are unknown, a segmentation procedure is performed using an evolving level set function, guided by edges and image derivatives.

space-time segmentation based on a joint entropy with estimation of Nonparametric distributions

1st international conference on scale space and variational methods in computer vision

This paper deals with video segmentation based on motion and spatial information. Classically;the nucleus of the motion term is the motion compensation error (NICE) between two consecutive frames. Defining a motion-based energy as the integral of a, function of the NICE over the object domain implicitly results in making an assumption on the MCE distribution: Gaussian for the square function, Laplacian for the absolute value, or other parametric distributions for functions used in robust estimation. However, these assumptions are generally false. Instead, it is proposed to integrate a function of (an estimation of) the NICE distribution. The function is taken such that the integral is the Ahmad-Lin entropy of the MCE, the purpose being to be more robust to outliers. Since a motion-only approach can fail in homogeneous areas, the proposed energy is the joint entropy of the NICE and the object color. It is minimized using active contours.

In the standard scale space approach one obtains a scale space representation u : R(d) x R(+) -> R of an image f epsilon L(2) (R(d)) by means of an evolution equation on the additive group (R(d), +). However, it is common to apply a wavelet transform (constructed via a representation U of a Lie-group G and admissible wavelet psi) to an image which provides a detailed overview of the group structure in an image. The result of such a wavelet transform provides a function g -> (U(g)psi, f)(L2(R)(2)()) on a group G (rather than (R(d), +)), which we call a score. Since the wavelet transform is unitary we have stable reconstruction by its adjoint. This allows us to link operators on images to operators on scores in a robust way. To ensure U-invariance of the corresponding operator on the image the operator on the wavelet transform must be left-invariant. Therefore we focus on left-invariant evolution equations (and their resolvents) on the Lie-group G generated by a quadratic form Q on left invariant vector fields. These evolution equations correspond to stochastic processes on G and their solution is given by a group convolution with the corresponding Green's function, for which we present an explicit derivation in two particular image analysis applications. In this article we describe a general approach how the concept of scale space can be extended by replacing the additive group R(d) by a Lie-group with more structure.

A geometric variational framework for simultaneous registration and parcellation of homologous surfaces

引用

1st international conference on scale space and variational methods in computer vision

作者： Lord, Nicholas A. Ho, Jeffrey Vemuri, Baba C. Eisenschenk, Stephan Univ Florida Gainesville FL 32611 USA

ISBN: (纸本)9783540728221

In clinical applications where structural asymmetries between homologous shapes have been correlated with pathology, the questions of definition and quantification of 'asymmetry' arise naturally. When not only the degree but the position of deformity is thought relevant;asymmetry localization must also be addressed. Asymmetries between paired shapes have already been formulated in terms of (non-rigid) diffeomorphisms between the shapes. For the infinity of such maps possible for a given pair, we define optimality as the minimization of deviation from isometry under the constraint of piecewise deformation homogeneity. We propose a novel variational formulation for segmenting asymmetric regions from surface pairs based on the minimization of a functional of both the deformation map and the segmentation boundary;which defines the regions within which the homogeneity constraint is to be enforced. The functional minimization is achieved via a quasi-simultaneous evolution of the map and the segmenting curve, conducted on and between two-dimensional surface parametric domains. We present examples using both synthetic data and pairs of left and right hippocampal structures;and demonstrate the relevance of the extracted features through a clinical epilepsy classification analysis.

Identification of grain boundary contours at atomic scale

Nowadays image acquisition in materials science allows the resolution of grains at atomic scale. Grains are material regions with different lattice orientation which are typically not in equilibrium. At the same time, new microscopic simulation tools allow to study the dynamics of such grain structures. Single atoms are resolved in the experimental and in the simulation results. A qualitative study of experimental images and simulation results and the comparison of simulation and experiment requires the robust and reliable extraction of mesoscopic properties from these microscopic data sets. Based on a Mumford-Shah type functional, grain boundaries are described as free discontinuity sets at which the orientation parameter for the lattice jumps. The lattice structure itself is encoded in a suitable integrand depending on the local lattice orientation. In addition the approach incorporates solid-liquid interfaces. The resulting Mumford-Shah functional is approximated with a level set active contour model following the approach by Chan and Vese. The implementation is based on a finite element discretization in space and a,step size controlled gradient descent algorithm.

Level set methods for watershed image segmentation

In this work a marker-controlled and regularized watershed segmentation is proposed. Only a few previous studies address the task of regularizing the obtained watershed lines from the traditional marker-controlled watershed segmentation. In the present formulation, the topographical distance function is applied in a level set formulation to perform the segmentation, and the regularization is easily accomplished by regularizing the level set functions. Based on the well-known Four-Color theorem, a mathematical model is developed for the proposed ideas. With this model, it is possible to segment any 2D image with arbitrary number of phases with as few as one or two level set functions. The algorithm has been tested on real 2D fluorescence microscopy images displaying rat cancer cells, and the algorithm has also been compared to a standard watershed segmentation as it is implemented in MATLAB. For a fixed set of markers and a fixed set of challenging images, the comparison of these two methods shows that the present level set formulation performs better than a standard watershed segmentation.

In this paper we look at how camera networks can be used in the healthcare industry for remote patient monitoring. This type of network would be installed in the home and have the ability to alert officials should an emergency arise. A network of this kind could be of benefit to many, and in particular to the growing number of elderly citizens by helping them to maintain their independent lifestyles as they mature. Camera networks play an important role in many other tasks as well, from surveillance to virtual environments. For this application, it is very important to consider how the camera network is set up. To this aim we explore the steps of designing and building a small-scale camera network, which incorporates background subtraction methods to monitor an individual's movement throughout the living space, and for this study is restricted to a single room. In the final implementation multiple cameras would be used to determine the internal and external parameters of each and to improve the background subtraction accuracy. In this paper we look at the use of a single camera to gather visual data and to investigate background subtraction techniques.

Combining different types of scale space interest points using canonical sets

scale space interest points capture important photometric and deep structure information of an image. The information content of such points can be made explicit using image reconstruction. In this paper we will consider the problem of combining multiple types of interest points used for image reconstruction. It is shown that ordering the complete set of points by differential (quadratic) TV-norm (which works for single feature types) does not yield optimal results for combined point sets. The paper presents a method to solve this problem using canonical sets of scale space features. Qualitative and quantitative analysis show improved performance over simple ordering of points using the TV-norm. © Springer-Verlag Berlin Heidelberg 2007.

A variational framework for spatio-temporal smoothing of fluid motions

1st international conference on scale space and variational methods in computer vision, SSVM 2007

ISBN: (纸本)9783540728221

In this paper, we introduce a variational framework derived from data assimilation principles in order to realize a temporal Bayesian smoothing of fluid flow velocity fields. The velocity measurements are supplied by an optical flow estimator. These noisy measurement are smoothed according to the vorticity-velocity formulation of Navier-Stokes equation. Following optimal control recipes, the associated minimization is conducted through an iterative process involving a forward integration of our dynamical model followed by a backward integration of an adjoint evolution law. Both evolution laws are implemented with second order non-oscillatory scheme. The approach is here validated on a synthetic sequence of turbulent 2D flow provided by Direct Numerical Simulation (DNS) and on a real world meteorological satellite image sequence depicting the evolution of a cyclone. © Springer-Verlag Berlin Heidelberg 2007.
