Block diagram for segmentation of eyeground images, based on the use of hybrid technologies for information processing is considered in this article. There has been proposed the use of two-stage filtration in frequency region for automated analysis of eyeground images. There has been also given a block diagram for segmentation of eyeground image in frequency region. In order to be analyzed the initial image is divided into typical segments. Method of amplitude quantisation of modes of corresponding frequencies has been used to increase quality of obtained image. Proposed method for analysis of eyeground image has been realized in the problem of revealing druses of optical nerve disk. Non-linear filtration by means of one-layer neural network for two-dimentional spectrum has been realized in this work. There has been also fulfilled visualization of the segment to be found by means of discrete Fourier inversion.
