Finding the splitting vector for image resolution up-conversion
This paper proposes a new single-frame image upconversion approach that uses prior information. The proposed method overcomes the drawbacks of the Kondo 2001 where the class membe...

System Calibration and Statistical Image Reconstruction for Ultra-High Resolution Stationary Pinhole SPECT
For multi-pinhole SPECT, iterative reconstruction algorithms are preferred over analytical methods, because of the often complex multi-pinhole geometries and the ability of iterat...

New Results on Visibility in Simple Polygons
We show that (A), 14 points on the boundary of a Jordan curve, and (B), 16 points in convex position encircled by a Jordan curve, cannot be shattered by interior visibility domains...

Multi-stack Boundary Labeling Problems
The boundary labeling problem was recently introduced in [5] as a response to the problem of labeling dense point sets with large labels. In boundary labeling, we are given a recta...

Constrained image segmentation from hierarchical boundaries
In this paper, we address the problem of constrained segmentation of natural images, in which a human user places one seed point inside each object of interest in the image and th...
