1. Deep Perceptual Loss and Similarity
Sammanfattning : This thesis investigates deep perceptual loss and (deep perceptual) similarity; methods for computing loss and similarity for images as the distance between the deep features extracted from neural networks. The primary contributions of the thesis consist of (i) aggregating much of the existing research on deep perceptual loss and similarity, and (ii) presenting novel research into understanding and improving the methods.

4. En perceptuell och akustisk studie av svenskans koronaler i ett dialektperspektiv
Sammanfattning : The purpose of this dissertation is to contribute to a typology of the Swedish language as it was spoken in the entire Swedish speaking area around the year 2000. Specifically, the plan is to base this typology solely on different pronunciations of the four coronal consonants /t, d, n/ and /l/. LÄS MER
5. Perceptual and Squared Error Aspects in Speech and Audio Coding
Sammanfattning : In the process of quantization, speech and audio signals are changed. This thesis contains four papers concerned with comparing and minimizing different measures to quantify the changes introduced. Before quantization the signal can be transformed to another domain. Transforms related to the discrete Fourier transform allow for e. LÄS MER
