Praktické řešení porovnání rastrového obrazu mincí nezávisle na rotaci

Abstract

This bachelor thesis is aimed with the possibilities of the comparison raster images of coins, where the main emphasis is placed on the elimination of image rotation. For the most part this work is aimed with the possibilities of a suitable pre-processing of image and the following rotation of coins, so that in the best case the image of the coin always well turned for further comparison. For this purpose is created an application for multiple pre-processing of images with the possibility of set parameters for the experimental testing over large collection of data containing around. 10000 coins. Each method is practice tested over a collection of pictures and the results of these tests are always included at the end of relevant chapters.
