In this paper, we consider saliency detection problems from a unique perspective. We provide an implicit representation for the saliency map using level set evolution (LSE), and then combine LSE approach with energy functional minimization (EFM). Instead of introducing sophisticated segmentation procedures, we propose a flexible and lightweight LSE-EFM

The RLE sparse level set representation has many beneficial characteristics: (1) highly scalable, (2) fast to access randomly, (3) sequential traversal of the narrow band is optimal, (4) approximate distance values are provided throughout the bounding volume, and (5) easily adapted to work with the large majority of existing level set methods developed

On the Integration of Fuzzy Level Sets
2015We study the integration of fuzzy level sets associated with a fuzzy random variable when the underlying space is a separable Banach space or a weak star dual of a separable Banach space. In particular, the expectation and the conditional expectation of fuzzy level sets in this setting are presented.

Mutual Segmentation with Level Sets
2006 Conference on Computer Vision and Pattern Recognition Workshop (CVPRW'06), 2006We suggest a novel variational approach for mutual segmentation of two images of the same object. The images are taken from different views, related by projective transformation. Each of the two images may not provide sufficient information for correct object-background delineation.

In many applications it is necessary to track a moving and deforming boundary on the plane from infrequent, sparse measurements. For instance, each of a set of mobile observers may be able to tell the position of a point on the boundary. Often boundary components split, merge, appear, and disappear over time. Data are typically sparse and noisy and the

On Polynomials with Related Level Sets
Canadian Mathematical Bulletin, 1970If p is a polynomial in one real variable and p(x) = p(-x) then p has only even powers of x and is thus a polynomial in x2. If p is a polynomial in n variables and p(x1, …, xn) = p(y1, …, yn) when x12 + … + xn2 = y12+ … + yn2 then p is a polynomial in q where q(x1, …, xn) = x12 + … + xn2.

Level Sets and Distance Functions
2000This paper is concerned with the simulation of the Partial Differential Equation (PDE) driven evolution of a closed surface by means of an implicit representation. In most applications, the natural choice for the implicit representation is the signed distance function to the closed surface. Osher and Sethian propose to evolve the distance function with

We propose a novel region based segmentation technique using dictionary learning. In a previous work we have developed a method which uses a set of pre-specified Legendre basis functions to perform region based segmentation of an object in presence of heterogeneous illumination.

Motion segmentation with level sets
Proceedings 1999 International Conference on Image Processing (Cat. 99CH36348), 1999Motion segmentation is an important problem in video processing and compression, and in computer vision. It is usually performed by either first estimating a field of motion parameters and then segmenting it, or by applying joint motion estimation and segmentation.
