    • The invention can be used in a wide range of fields including space applications, for observing, measuring and surveying the earth surface with satellites, civilian and military aeronautics, for x-ray images and security applications, as well as in general industrial image processing and image generation applications. The invention uses the advantages of the wavelet transformation, a mathematical mapping between spaces, and in particular the advantages of interpolating wavelets, to improve the transmission of endless, continually growing, non-bordered images using a small amount of memory. The invented procedure and the proposed implementation of the procedure describe a complete wavelet transformation system which is used as a decorrelating transformation for digital or digitized input data. The invention also covers an inverse wavelet transformation system for reverting the wavelet transformation system operations.

    • In a process and unit for gradual decoding, archiving and graphic display of progressively decoded image data, time intervals between the time points of consecutive decoding steps, during which network users receive ever more refined image resolution when downloading image data from a central network server to the client computer using transferred and decoded partial data quantities ΔLi as preview images, are generated with abbreviated time spans that are optimized with respect to minimization of system usage by the decoding system. For this purpose, the receiving data rates for transfer of the individual partial data quantities, which are taken into account through improvements generated by the individual decoding steps of a quality metric showing the degree of image resolution and the temporary usage of the decoding system upon determination of the decoding time points. The wait times between the time points of directly consecutive decoding steps are calculated using statistical image quality parameters of received partial image data in such a manner that the decoding steps which do not lead to a perceptible improvement in the quality of a reconstructed image are suppressed.
