1	Nonattribution Properties of JPEG Quantization Tables Tuladhar, Punnya 17 December 2010 (has links) In digital forensics, source camera identification of digital images has drawn attention in recent years. An image does contain information of its camera and/or editing software somewhere in it. But the interest of this research is to find manufacturers (henceforth will be called make and model) of a camera using only the header information, such as quantization table and huffman table, of the JPEG encoding. Having done research on around 110, 000 images, we reached to state that "For all practical purposes, using quantization and huffman tables alone to predict a camera make and model isn't a viable approach". We found no correlation between quantization and huffman tables of images and makes of camera. Rather, quantization or huffman table is determined by the quality factors like resolution, RGB values, intensity etc.of an image and standard settings of the camera. identification of camera huffman table quantization table jpeg exif data correlation of camera and quantization

3	Aplikace pro geotagging fotografií / Photography Geotagging Application Kodeš, Daniel January 2011 (has links) This master thesis describes development of Photography Geotagging Application from an introduction to the issues, through the analysis and design to the resulting implementation. The reader should be able understand to issues of time in geotagging using the GPS tracks records. He will also understand where and how metadata are stored. The big part of thesis is dedicated to the implementation of application which leads the reader through building the application architecture, the photography representation and loading their metadata with program ExifTool. Gradually will be explained the convertors of coordinates and GPS track parsers, which are used to synchronization. The final application allows the user synchronize photography with GPS track and display them on the map.
4	Systém pro správu sbírek fotografií / System for Management of Photographic Collections Čermák, Pavel January 2014 (has links) This thesis deals with the management of digital photos by metadata contained in the photos. The thesis describes the structure of the formats JFIF, TIFF, RAW and EXIF format for storing metadata into photos. In the next part of this thesis is described the design and implementation of a simple photo management application. The main functionality of the application is focused on bulk editing EXIF metadata in the photos. In the conclusion of this thesis there's a proof of results and discussion about further extension options.
