Design of algorithm for anonymization of ultrasound data
 Bugnerová, Pavla ; Hesko, Branislav (referee) ; Harabiš, Vratislav (advisor)
This master’s thesis is focused on anonymization of ultrasound data in DICOM format. Haar wavelet belonging to Daubechies wavelet family is used to detect text areas in the image. Extraction of the text from the image is done using a free tool - tesseract OCR Engine. Finally, detected text is compared to sensitive data from DICOM metadata using Levenshtein - edit distance algorithm.
