DEVICE FOR DATA COMPRESSION Russian patent published in 1997 - IPC

FIELD: computer engineering. SUBSTANCE: device has data compression units 1-3 on each processing level. Output of generalized data and generalization feature output are connected to information input and generalization feature input of adjacent higher-level unit. Each compression unit has local center generator 4, subtraction unit 5, adaptive non-regular threshold sampling unit 6, sampler 7, generalized data calculation unit 8, generalized feature generator 9. Another claim of invention describes device design in which adaptive regular sampling unit 10 and adaptive non-regular non-threshold sampling unit 11 are introduced. EFFECT: increased speed, increased compression ratio. 4 cl, 1 tbl, 11 dwg
