Abstract
This paper present image coding which is gained many researchers attention in order to improve the quality of
image after the compression process. Since this is expended most computing resources and research which is related not
only to search for a mathematical transformation, but also to study the characteristics of visual perception of the image
features and fail-safe transmission of images via communication channels. There are many methods of image coding with
neural networks of 2D SOFM kohonen map have been suggested and investigated. The coding schemes are proposed
methods vector quantization as the original image, and the spatial frequency image component derived from the adaptive to
the contours of the two-dimensional analysis and synthesis. The calculation of the computational cost in compression based
on Kohonen maps. The methods are characterized by a high level of adaptation due to the introduction of educational stage
that provides for the increase of multiplication ratio and high quality of image restarting after coding. The modified method
of image multiplexing based on characteristic feature of the given method is vector digitizing of image components. This
paper considers the coding problem of photo realistic images, presented in a digital form. The characteristic feature of the
method is the application of pair exchange, this increases processing speed and sorting of data arrays. However the result
of proposed method is shown the image quality after compression processor. Using this approach the differences or lost
pixels between the image after and before compression processer are considered. The propose method may useful for
image representation and image coding researcher and such related field.
