1. 1. Virtual H&E Staining Using PLS Microscopy and Neural Networks

   University essay from Lunds universitet/Matematik LTH

   Author : Sally Vizins; Hanna Råhnängen; [2024]
   Keywords : Deep learning; Virtual staining; Skin tissue; Hematoxylin Eosin; H E; Pathology; Carcinoma; Point light source illumination; Neural Networks; GANs; Generative adversarial networks; CNNs; Convolutional neural networks; Relativistic generative adversarial network; Unet; Digital microscopy; Attention-Unet; Dense-Unet; Mathematics and Statistics;

   Abstract : 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.

3. 2. Virtual Staining of Blood Cells using Point Light Source Illumination and Deep Learning

   University essay from Lunds universitet/Matematik LTH

   Author : Joel Wulff; [2022]
   Keywords : Deep learning; virtual staining; blood; cells; GANs; Generative adversarial networks; CNNs; convolutional neural networks; ESRGAN; Unet; digital microscopy; Mathematics and Statistics;

   Abstract : 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

4. 3. Efficient Simulation and Rendering of Sub-surface Scattering

   University essay from Medie- och Informationsteknik; Tekniska högskolan

   Author : Apostolia Tsirikoglou; [2013]
   Keywords : subsurface scattering; SSS; translucent materials; BSSRDF; shader; V-Ray; Maya; better dipole; quantized-diffusion;

   Abstract : 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

5. 4. An Illumination Model for Realistic Rendering of Snow Surfaces

   University essay from Institutionen för informationsteknologi

   Author : Fei Liu; [2010]
   Keywords : ;

   Abstract : 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

6. 5. Clustered Importance Sampling for Fast Reflectance Rendering

   University essay from Institutionen för teknik och naturvetenskap; Tekniska högskolan

   Author : Oskar Åkerlund; [2008]
   Keywords : ;

   Abstract : 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
