The adaptive filter for a one-dimensional signal for the reduction of the block effect and filtering method

摘要

it is a one-dimensional signal adaptive end of pipe and an adaptive filter of a one-dimensional signal is described.the adaptive end of pipe of a one-dimensional signal, a blockeffekt images can be reduced when a part of a predetermined size blocks is assembledincludes the following steps: applying a one-dimensional window of a predetermined size along the boundaries of blocksa predetermined gradientenoperation at each pixel within the one-dimensional window; calculate schwellwerten for each pixel within the one-dimensional fensagesby a predetermined function of a quantisierungsschrittes is produced; comparing the results of the gradientenoperation at each pixel within the window with the one-dimensionalthe calculated thresholda vergleichsergebnis as binary kantenkarte to generate a one-dimensional filterfensters; apply a predetermined size on the produced binary kantenkarte,in order to generate the binu00e4rwertes wichtungswerte using the one-dimensional filterfenster belongs; and performing a filtering using the generated wichtungswerte,in order to generate new bildpunktwerte.thus, the blockrauschen from the image are eliminated, and the blocks based on image is restored, so as to enhance the image.the compressed form is produced.
