I am a recent graduate in computer engineering from the Department of Computer Engineering, University of Peradeniya.

My main research interest ivolve around applying Machine Learning and Computer Vision techniques in biomedical context.
I am also interested in building low-energy pervasive sensing applications using Spiking Neural Networks (SNN) on event-based data obtained from neuromorphic vision sensors.

Group: Isuri Devindi, Sashini Liyanage
Project Page | Repository | Report
2023

A pre-packaged software solution containing a set of low-complexity algorithms for QRS-peak detection and ECG signal compression addressing the null-power consumption environments, along with a Spiking Neural Network implementation to classify ECG beats based on arrhythmia conditions.

Reconstructing Highly Degraded License Plates

Reconstructing Highly Degraded License Plates

Group: Isuri Devindi, Sashini Liyanage, Aminda Amarasinghe, N. Varnaraj
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

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.

Remote Proctoring System

Project Page | Repository | Video
2021

A single device which integrates the hardware and software components needed to conduct an examination in the currently implemented system, which will provide a seamless process for the proctors and students involved in an examination.

8-bit single cycle processor

8-bit single cycle processor

Group: Isuri Devindi, Dinura Dissanayake
Repository
2020

An 8-bit single cycle CPU with associated memory hierarchy. The processor includes an ALU, register file, control logic, forwarding unit, data memory, data cache, instruction memory and instruction cache simulated with Verilog HDL.
