Multispectral Image Processing
Li, You ; Juránek, Roman (oponent) ; Zemčík, Pavel (vedoucí práce)
With the rapid development of multispectral image imaging technology in recent decades, the images acquired by imaging systems not only contain the RGB color bands in daily life but also have multispectral color bands and high spatial resolution in multispectral image data. This makes the images contain rich information about the characteristic target regions. Image fusion is also an important branch in the field of image processing, where multiple images from the same region at the same height are fused into a single image. Then the correlation between the spectral information of the multispectral images is enhanced. So that the information in the image is not lost. This thesis contains a description of the design and implementation of a multispectral image system, preprocessing of multispectral images, the fusion of multispectral images, and principal component analysis. Finally, an evaluation of the whole system is presented.

Detekce živosti lidské ruky z multispektrálních snímků
Lebedeva, Polina ; Malaník, Petr (oponent) ; Sakin, Martin (vedoucí práce)
Tato bakalářská práce se zaměřuje na detekci živosti lidské ruky z multispektálních snímku. Hlavním cílem je návrh a implementace algoritmu pro rozpoznávání živé ruky a falzifikátů na základě analýzy snímků ruky osvětlené specifickými vlnovými délkami. V práci se popisují různé techniky pro extrahování důležitých rysů ze snímků, jejich zpracování a způsoby, jak se může určit živost.
