IMAGE COMPRESSION METHOD Russian patent published in 2013 - IPC H03M7/30 G06T9/00 

FIELD: information technology.

SUBSTANCE: image compression method, based on excluding a certain portion of information, wherein the information is excluded from the space domain through numerical solution of Poisson or Laplace differential equations, and subsequent estimation of the difference between the obtained solution and actual values at discrete points of the image; generating an array of boundary conditions, which includes a considerable number of equal elements which is compressed, and the image is reconstructed by solving Poisson or Laplace partial differential equations using the array of boundary conditions.

EFFECT: eliminating loss of image integrity, high efficiency of compressing images having large areas of the same tone or gradient and maintaining contrast of boundaries between different objects of an image.
