Realistic Visualisation of Alcoholic Beverages Using Distributed Raytracing
Fabík, Jiří ; Maršík, Lukáš (referee) ; Polok, Lukáš (advisor)
This work is about a realistic visualization technique called raytracing. It studies its original form, its extensions and optimizations. Raytracing casts rays through pixels and follows their propagation in the scene, according to the physical laws. It enables rendering of correct shadows, reflections and refractions. Distributed raytracing serves for better visualization and advanced effects. One ray is replaced with a beam of rays that allows soft shadows, fuzzy translucency, depth of field and antialiasing. With the increasing number of rays, the render time rises as well, so it is needed to use some optimization techniques and tools. A way of using this rendering method for visualization of alcoholic beverages is also described.

Braille Reader
Fabík, Jiří ; Svoboda, Pavel (referee) ; Maršík, Lukáš (advisor)
This thesis deals with image processing, specifically scanned Braille documents. It is about recognition of Braille cells, followed by transferring to plain text. Braille dots are recognized on the basis of bright and dark parts, which are created during scanning. After connection to the characters, they are converted to plain text by means of the character set. It also locates positions of possible errors to make it easier to correct the final text.
