Image Compression Using Wavelets
 Mokrejš, Jiří ; Kyselý, František (referee) ; Říha, Kamil (advisor)
This bachelor´s thesis describes issues of wavelet compression, which is today already in common use mainly at work with digital photographs or other pictures. Saving of space regarding sizes of files is the main reason of that. There are main image formats and types of compression suitable for editing pictures desribed in this thesis. In case of lossy image compression, distortion occurs and blocking artefacts can be created. It is unwanted effect that´s why it is neccesary to use suitable data stream, compression´s rate or coding type. So the focus is on discrete wavelet transform, which uses so-called wavelets and the Haar´s wavelet is the best known of all. Next chapter of this work explores colour spaces, in which can be a picture displayed. In case of coding and encoding it is model RGB and YCbCr. Not least there is mentioned term of picture decomposition. It is possible to demonstrate mentioned functions on created java aplication, which is part of this bachelor´s thesis.
