Clustering via Random Walk Hitting Time on Directed Graphs
In this paper, we present a general data clustering algorithm which is based on the asymmetric pairwise measure of Markov random walk hitting time on directed graphs. Unlike tradi...

A scaled morphological toggle operator for image transformations
Scale dependent signal representations have proved to be useful in several image processing applications. In this paper, we define a toggle operator for binarization/segmentation...

The Hash History Approach for Reconciling Mutual Inconsistency
We introduce the hash history mechanism for capturing dependencies among distributed replicas. Hash histories, consisting of a directed graph of version hashes, are independent of...

Reconfigurable Parallel Sorting and Load Balancing: HeteroSort
HeteroSort load balances and sorts within static or dynamic networks. Upon failure of a node or path, HeteroSort uses a genetic algorithm to minimize the distribution path by optim...

Ghost-free High Dynamic Range Imaging
Most high dynamic range image (HDRI) algorithms assume stationary scene for registering multiple images which are taken under different exposure settings. In practice, however, the...
