Public Key Locally Decodable Codes with Short Keys
This work considers locally decodable codes in the computationally bounded channel model. The computationally bounded channel model, introduced by Lipton in 1994, views the channe...

A Linear Time and Space Algorithm for Detecting Path Intersection
For discrete sets coded by the Freeman chain describing their contour, several linear algorithms have been designed for determining their shape properties. Most of them are based ...

Efficient and low-complexity image coding with the lifting scheme and modified SPIHT
—In this paper, we propose an efficient and low complexity image coding algorithm based on the lifting wavelet transform and listless modified SPIHT (LWT-LMSPIHT). LWT-LMSPIHT jo...
