Repository
| Report
| Video
2022
Demonstration on how traditional image processing techniques such as Otsu thresholding, morphological transformation, contouring, spatial and frequency domain filtering, and degradation modeling can be used to restore highly distorted images along with the limitations of the traditional image processing theoretical techniques.
Compiler for COOL language
Group: Isuri Devindi, Sashini Liyanage
Repository
2022
The combination of a lexer, parser, semantic analyser, and code generator that can be used to compile programs written in Cool programming language. All components were built using C++. Lexical Analyzer was built using a lexical analyzer generator called "flex" and the Parser using a helper tool called "bison" and a package for manipulating Abstract Syntax Trees.
