Abstract
High Dynamic Range Imaging (HDRI) predstavuje expandujúcu sféru spracovania obrazu s netriviálnymi závislosťami k rôznym oborom ako syntéza obrazu, počítačové videnie, digitálna fotografia. Táto bakalárska práca sa zaoberá práve využitím HDRI v digitálnej fotografii. Konvenčné fotoaparáty dnes nie sú schopné zaznamenať plný tonálny rozsah scény. Preto ak chceme zachytiť scénu s vysokým dynamickým rozsahom, musíme zvoliť nastavením expozície iba časť tónov, ktoré budú korektne zachytené. Ostatná časť fotografie ostáva bez kresby. Metódou predstavenou a implementovanou v rámci tejto práce je možné na základe viacerých rôzne exponovaných fotografií vytvoriť HDR obraz odrážajúci reálne hodnoty tónov.
High Dynamic Range Imaging (HDRI) is an emerging field in image postprocessing with non-trivial relations to many different areas, such as image synthesis, computer vision, video and image processing, digital photography, special effects among others. This bachelor's thesis deals with the usage of HDRI in digital photography. Conventional digital cameras are not able to record the full tonal range of the scene. Therefore, if we want to capture a high dynamic range scene, by setting the exposure time we have to choose only a small range of tones which will be well depicted. The rest of the photograph will loose important detail. The method presented and implemented in the scope of this thesis enables us to create HDR picture with realistic values of tones out of several differently exposured photographs.
