Rekonstrukce obrazu v digitální holografické mikroskopii s pomocí GPU

Image reconstruction in digital holographic microscopy on GPU
Abstract:
Cieľom tejto práce je implementovať a optimalizovať vybrané algoritmy spracovania obrazu, používané v digitálnej holografickej mikroskopii, na GPU. Ide o naväzovanie fáze 2-D signálu a o aproximáciu obrazu pomocou polynomiálneho povrchu. Tieto algoritmy sú popísané a použité optimalizácie sú zdôraznené. GPU implementácia je porovnaná s CPU implementáciou z hľadiska výkonu a presnosti na rôznych vstupných …more
Abstract:
The aim of the thesis is to implement and optimize chosen image processing algorithms used in digital holographic microscopy on the GPU. The algorithms are 2-D phase unwrapping and polynomial surface fitting. They are described and certain used optimizations are pointed out. The results chapter shows the performance and precision of the GPU implementation compared to CPU on various input images.
