Image Compression Using the Wavelet Transform
Kaše, David ; Klíma, Ondřej (referee) ; Bařina, David (advisor)
This thesis deals with image compression using wavelet, contourlet and shearlet transformation. It starts with quick look at image compression problem a quality measurement. Next are presented basic concepts of wavelets, multiresolution analysis and scaling function and detailed look at each transform. Representatives of algorithms for coeficients coding are EZW, SPIHT and marginally EBCOT. In second part is described design and implementation of constructed library. Last part compare result of transforms with format JPEG 2000. Comparison resulted in determining type of image in which implemented contourlet and shearlet transform were more effective than wavelet. Format JPEG 2000 was not exceeded.

Educational Application of Compression Algorithms
Kaše, David ; Tříska, Vít (referee) ; Košař, Vlastimil (advisor)
This bachelor thesis studies the basic principles and methods of compression algorithms. After identification of these basic methods, a few algorithms are selected to represent these methods. For the selected algorithms is designed an aplication, which is then implemented for education with emphasis on visualization of algorithms steps. Application development takes into account the addition of additional algorithms.
