1. Virtual H&E Staining Using PLS Microscopy and Neural Networks
University essay from Lunds universitet/Matematik LTHAbstract : Histopathological examination, crucial in diagnosing diseases such as cancer, traditionally relies on time- and resource-consuming, poorly standardized chemical staining for tissue visualization. This thesis presents a novel digital alternative using generative neural networks and a point light source (PLS) microscope to transform unstained skin tissue images into their stained counterparts.

2. Virtual Staining of Blood Cells using Point Light Source Illumination and Deep Learning
University essay from Lunds universitet/Matematik LTHAbstract : Blood tests are an important part of modern medicine, and are essentially always stained using chemical colorization methods before analysis by computational or manual methods. The staining process allows different parts of blood cells to be discerned that would be unnoticeable in unstained blood. READ MORE

3. Efficient Simulation and Rendering of Sub-surface Scattering
University essay from Medie- och Informationsteknik; Tekniska högskolanAbstract : In this thesis, a new improved V-Ray subsurface scattering shader based on the improved diffusion theory is proposed. The new shader supports the better dipole and the quantized diffusion reflectance model for layered translucent materials. READ MORE

4. An Illumination Model for Realistic Rendering of Snow Surfaces
University essay from Institutionen för informationsteknologiAbstract : In this thesis work, several prominent visual effects of a snow surface under a strong light source, for instance, the sun, have been identified and modeled, which includes glittering, micro shadows and regional translucency due to subsurface light scattering. The glittering effect was implemented using blooming technique which makes candidate pixels’ colours bleed into their neighbours. READ MORE

5. Clustered Importance Sampling for Fast Reflectance Rendering
University essay from Institutionen för teknik och naturvetenskap; Tekniska högskolanAbstract : In realistic image synthesis, a major challenge is how to account for largescale, complex lighting environments in an ecient and robust way. This thesis presents a simple and ecient method for bidirectional importance sampling from large-scale illumination sources. READ MORE
