Hierarchical Cell Structures for Segmentation of Voxel Images
We compare three hierarchical structures, S15, C15, C19, that are used to steer a segmentation process in 3d voxel images. There is an important topological difference between C19...

On the perimeter of fat objects
We show that the size of the perimeter of (, )-covered objects is a linear function of the diameter. Specifically, for an (, )-covered object O, per(O) c diam(O) sin2 , for a pos...

Range aggregate structures for colored geometric objects
A set of n colored objects (points/hyperboxes) lie in IRd . Each object has a weight associated with it. Given a query orthogonal range q, for each distinct color c of the objects...

Searching for Frequent Colors in Rectangles
We study a new variant of colored orthogonal range searching problem: given a query rectangle Q all colors c, such that at least a fraction of all points in Q are of color c, mus...
