Efficiency of search algorithms for the impression of a seal in the document image

The article deals with peculiarities in the search algorithm, which uses the Hough transformation, of the impression of a seal in the document image. The results of the program simulation and those of the analysis of effectiveness for the basic search algorithm and the modified one with the use of the brightness gradient are given

Keywords: Hough transformation, search algorithms, image processing, brightness gradient, program modeling.
