Exploring Discrete Cosine Transform For Multi-Resolution Analysis, Safdar Ali Syed Abedi
Exploring Discrete Cosine Transform For Multi-Resolution Analysis, Safdar Ali Syed Abedi
Computer Science Theses
Multi-resolution analysis has been a very popular technique in the recent years. Wavelets have been used extensively to perform multi resolution image expansion and analysis. DCT, however, has been used to compress image but not for multi resolution image analysis. This thesis is an attempt to explore the possibilities of using DCT for multi-resolution image analysis. Naive implementation of block DCT for multi-resolution expansion has many difficulties that lead to signal distortion. One of the main causes of distortion is the blocking artifacts that appear when reconstructing images transformed by DCT. The new algorithm is based on line DCT which …
Scoresvg: A New Software Framework For Capturing The Semantic Meaning And Graphical Representation Of Musical Scores Using Java2d, Xml, And Svg, Geoffrey Alan Bays
Scoresvg: A New Software Framework For Capturing The Semantic Meaning And Graphical Representation Of Musical Scores Using Java2d, Xml, And Svg, Geoffrey Alan Bays
Computer Science Theses
ScoreSVG implements a three-tiered software architecture that generates musical scores in scalable vector graphics (SVG), something no other known music editor has done. SVG is non-proprietary XML-based format that renders graphical content into a web browser equipped with a SVG plugin. Scores in SVG can be scripted to produce interactive music theory examples, or make other graphical score changes impossible in any other format. Large music score editors such as Finale and Sibelius output to proprietary file formats, or Postscript (.ps) files that are not interchangeable or modifiable once created. Open source efforts such as LilyPond or Guido require the …

Delay And Power Reduction In Deep Submicron Buses, Sharareh Babvey
Computer Science Theses
As technology scales down, coupling between nodes of the circuits increases and becomes an important factor in interconnection analysis. In many cases like the deep submicron technology (DSM), the coupling between lines (inter-wire capacitance) is strong and the energy consumption caused by parasitic capacitance is non-negligible. In this work, we employ the differential low-weight encoding [1] to reduce energy and delay (transmission cost) on DSM buses. We propose an enumeration method that reduces the encoder table-size from O(2n) words to O(n) words, for an n-bit DSM bus, and so reduces the memory complexity significantly and facilitates energy and delay reduction …
