This paper deals with the technology of generation and identification of 2D IIR-filter characteristics. For the characteristic identification, small test fragments of an image are used; these fragments are formed from a distorted image using the prior information on the geometric form of objects. 2D IIR-filter is generated as parallel casual filters with a mask in the form of a quadrant. A distributed system architecture is proposed with consideration of data parallelism for high-resolution images and the parallel message passing with regard to the IIR-filter structure. The paper was prepared on the basis of the authors' report at the International Conference on Parallel Computing Technologies (PaVT-2010; http://agora.guru.ru/pavt).

Keywords: digital image processing, IIR-filter (infinite impulse response filter), identification, distributed computing
