Original Abstract

This paper deals with the Matlab application used for the detection of the most common faults present on scanned copies of old optical sound tracks, using benefits of image processing toolbox. Algorithms developed for transversal scratches, longitudinal scratches and dirt blotches detection are descibed. The application allows user to load scanned optical sound track, review it using various analysis tools and perform detection of selected fault type, review each detection step results and, where possible, change detection parameters to achieve the best possible result. Binary masks according to detected faults serve as an output. Additional functions of track analysis are for example the zoom function, evaluation of gray levels across and along the track, evaluation of histogram and simulation of selected fault impact with help of 3D spectrograms. Detection results using described algorithms implemented in previously mentioned appli cation are presented and discussed.
