Representations and transformations of color spaces via quaternions
 Tichý, Radek ; Druckmüller, Miloslav (referee) ; Hrdina, Jaroslav (advisor)
This thesis deals with quaternions for edge detection, particularly on image processing represented in various color spaces. First, the key concepts and the quaternion algebra properties are mentioned, then some of the commonly used color spaces are described and afterwards the thesis dedicates to the basic filters for edge detection in grayscale image. After that there are presented the color filters that use quaternions for color edge detection in RGB color space. Towards the end, these filters are used for color edge detection in HSV color space.
