Tiivistelmä
The main aim of the thesis was to develop a free software application for processing surveillance videos. Methods discussed in this thesis are mainly incorporated in the developed application. The open source Avisynth environment is intensively used both in the application for filtering video clips and in the thesis for gaining more deeper understanding of how video processing works. In this thesis I focus mostly on processing digital video material. Digital imaging is usually much more accurate than analog, but because the lack of storage capacity makes video compression necessary, the quality of video is often significantly decreased.
Before starting actual programming process, it was necessary to find out what features are essential for software used in forensic video editing. In this task the guidance given by forensic experts in NBI play big role. Main tools used in this project were: Python 2.6 as basic programming tool, PyQt 4.0 was used creating GUI for the software, Avisynth provides the tools for video editing, FFMPEG is being used for video compression, PDF library is being used for creating PDF files.
Open source software created in this project, enables all basic functions needed in forensic video processing. This sofware was named ForeVid for it's Forensic video editing features. With this software it is possible to resize, sharpen and cut video. Avisynth that is being used for powering video editing features, offers wide variety of filters. In ForeVid the user can take still photos and create videos or PDF documents. /Kir11
