The topic of the paper is important for the analysis of photo images when aiming to restore the initial form of an image. This paper examines a geometrically deformed photographed image, characterized by the lattice structure. Generally, the photographed image is minimally distorted (deformed). This feature is more common for regular geometric objects, such as squares, circles and straight lines. This paper aims to develop restoration procedure of geometrically deformed images, characterized by the lattice structure; to test the functioning of geometric transformations; to suggest the optimal method of image restoration, and to visually evaluate the quality of restored images. The paper presents an image restoration scheme. Detailed methods of each stage of the restoration procedure and their mathematical expressions are comprehensively outlined in the present work. Intermediate results of image processing are also provided. For this purpose, a specialized base of geometrically distorted images has been created for experimental studies Conclusions about restoration procedure of geometrically deformed images and separate stag-es of the employed methods are drawn based on the obtained results. Moreover, work-related literature is presented in this paper. |
