I am currently working as a Research Assistant at the Graphics and Vision (GrUVi) lab at SFU, where my work is mainly focused on creative shape modeling and design.
Research projects
Co-creative Modeling
ExquiMo (i.e., ExquisiteModeling), is a shape modeling tool based on the game of Exquisite Corpse. It is guided by the idea of improving the creativity of 3D shape designs through collaboration. (PDF, Data)

Semi-automatic Mesh Cutting
We developed a mesh cutting tool to manually draw the boundary of segmentation while assisting the user with semi-automatic rotation. Based on the current endpoint of the sketch, we predicted the potential subsequent position of the boundary point considering the minima rule. (PDF)

Shadow removal
Improving on a method for shadow removal from un-sourced imagery based on minimum entropy, we arrived at a shadow-free 3-band color image. More information can be found here: PDF.

Legibility classifier
Given a deformed letter in the English alphabet, we devised a model to automatically classify the letter as legible or illegible. The classifier would be helpful in measuring the usefulness of auto-generated calligrams. Our approach can be found here: PDF.

Drug MoA prediction
For my senior thesis, I worked with networks of drugs to predict unknown modes of action of drugs. I specifically focused on the unavailability of a specific similarity measure when connecting two distinct drugs in a drug network. I've proposed a "Friends of Friends" approach for similarity approximation by electing a mediator drug to indirectly find the similarity between a given drug pair. (Extended abstract)

Radar simulation
We developed a light-weight radar simulation for virtual maritime training environments that simulates the electromagnetic wave propagation of an actual radar system. The virtual radar, as we call it, is capable of detecting obstacles that fall within a particular radius of the ship which is navigated inside the virtual environment. Its mother project, Vidusayura, is funded by the National Research Council Sri Lanka. (PDF)

Virtual Eye
Virtual Eye is a sensor based mobile viewer which is able to interact with any remotely deployed virtual environment in real time. It serves as a virtual nautical telescope for Vidusayura maritime learning environment. More information can be found here. This project is affiliated with the Modelling and Simulation group at University of Colombo School of Computing.
