Detection of image rotation and scaling differences using phase correlation
Meduňa, Tomáš ; Druckmüller, Miloslav (referee) ; Hoderová, Jana (advisor)
This thesis deals with detection of rotation and scaling differences between two similar images by using phase correlation. Necessary mathematical basis such as Fourier transform and its properties is described and demonstrated on examples. Obtained algorithm was used to create an illustrative application.

Accelerated Image Resampling Library
Hamrský, Jan ; Bařina, David (referee) ; Polok, Lukáš (advisor)
This work deals with the task of image scaling using GPU paralelization. Portion of text is devoted to signal processing and his affection of whole result including measuring it's quality. Describtion of the most important methods including super-resolution is given further in the text. An important part of this thesis is library implementing choosen methods with usage of paralelization on graphic chip. Achieved results of paralelization are demonstrated on set of speed tests.
