  1. 6. Quality Assessment for Halftone Images

    University essay from Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska fakulteten

    Author : Johnny Elmèr; [2023]
    Keywords : Image Quality; Halftoning; Subjective Image Quality Assessment; Subjective Testing; Objective Image Quality Metrics;

    Abstract : Halftones are reproductions of images created through the process of halftoning. The goal of halftones is to create a replica of an image which, at a distance, looks nearly identical to the original. Several different methods for producing these halftones are available, three of which are error diffusion, DBS and IMCDP. READ MORE

  3. 7. LiDAR Point Cloud De-noising for Adverse Weather

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Johan Bergius; Jesper Holmblad; [2022]
    Keywords : Semantic Segmentation; Lidar point cloud; CNN; GAN; CycleGAN; Unsupervised; LiOR; DSOR; DROR; WADS;

    Abstract : Light Detection And Ranging (LiDAR) is a hot topic today primarily because of its vast importance within autonomous vehicles. LiDAR sensors are capable of capturing and identifying objects in the 3D environment. However, a drawback of LiDAR is that they perform poorly under adverse weather conditions. READ MORE

  4. 8. Depth of field post-processing using neural networks

    University essay from Lunds universitet/Matematik LTH

    Author : Otto Holmström; [2022]
    Keywords : Technology and Engineering;

    Abstract : It is possible to create images from a computer model closely resembling those taken with a physical camera. To improve the photo-realism and perceived quality of a rendered image, it is often desireable to add realistic effects that do not appear in computer graphics due to the camera model. READ MORE

  5. 9. Generative Adversarial Networks in Lip-Synchronized Deepfakes for Personalized Video Messages

    University essay from Lunds universitet/Matematik LTH

    Author : Johan Liljegren; Pontus Nordqvist; [2021]
    Keywords : Generative Adversarial Networks; GAN; Lip-Synchronization; Deepfake; Deep Learning; Autoencoder; WGAN; WGAN-GP; L1WGAN-GP; Skip-Connections; FID-Score; Mathematics and Statistics; Technology and Engineering;

    Abstract : The recent progress of deep learning has enabled more powerful frameworks to create good-quality deepfakes. Deepfakes, which are mostly known for malicious purposes, have great potential to be useful in areas such as the movie industry, education, and personalized messaging. READ MORE

  6. 10. Image Processing in MRI Guided Real-TimeAdaptive Radiotheraphy - Upsampling and Segmentation of Target Volume and Organs at Risk

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Shreyas Shivakumara; [2021]
    Keywords : ;

    Abstract : Magnetic Resonance Imaging (MRI) is a useful medical imaging technique that is used for cancer treatment.The major drawback of this method is the relatively long scan time, limiting its use for real time tracking of a potentially moving target during the radiotherapy session.
