New algorithms for computing directional discrete Fourier transforms
New algorithms for computing the Discrete Fourier Transform (DFT) spectra along different directions are derived and implemented. For computing the DFT spectrum along any given di...

Image Compression Using the Wavelet Transform on Textural Regions of Interest
This paper suggests a new image compression scheme, using the discrete wavelet transformation (DWT), which is based on attempting to preserve the texturally important image charac...

Generalizing Cook's Transformation to Imperative Stack Programs
Cook's construction from 1971 [4] shows that any two-way deterministic pushdown automaton (2DPDA) can be simulated in time O(n), where n is the length of its input string, and...

An Efficient Perception-based Adaptive Color to Gray Transformation
The visualization of color images in gray scale has high practical and theoretical importance. Neither the existing local, gradient based methods, nor the fast global techniques g...

Multithreaded Geant4: Semi-automatic Transformation into Scalable Thread-Parallel Software
This work presents an application case study. Geant4 is a 750,000 line toolkit first designed in the mid-1990s and originally intended only for sequential computation. Intel's...
