21. Improving fingerprint biometrics by local symmetry and fusion
Sammanfattning : Fingerprint recognition and biometrics in general have been significantly gaining attention within the last years, not least due to the biometric passport that has been introduced all over Europe and the American immigration management system US-VISIT. The tasks of fingerprint recognition can be broken down to smaller entities, i.e. LÄS MER
22. Generalization under Model Mismatch and Distributed Learning
Sammanfattning : Machine learning models are typically configured by minimizing the training error over a given training dataset. On the other hand, the main objective is to obtain models that can generalize, i.e., perform well on data unseen during training. LÄS MER
23. Physical properties of chromospheric features : Plage, peacock jets, and calibrating it all
Sammanfattning : The chromosphere is a complex and dynamic layer of the solar atmosphere, largely dominated by the local magnetic field configuration. It acts as an important interface between the photosphere below it and the hot corona above. However, studying this layer is not straightforward, as it is largely transparent in optical wavelengths.

24. Efficient Image Retrieval with Statistical Color Descriptors
Sammanfattning : Color has been widely used in content-based image retrieval (CBIR) applications. In such applications the color properties of an image are usually characterized by the probability distribution of the colors in the image. LÄS MER
25. Interpreting the Script : Image Analysis and Machine Learning for Quantitative Studies of Pre-modern Manuscripts
Sammanfattning : The humanities have for a long time been a collection of fields that have not gained from the advancements in computational power, as predicted by Moore´s law. Fields like medicine, biology, physics, chemistry, geology and economics have all developed quantitative tools that take advantage of the exponential increase of processing power over time. LÄS MER
