Abstract
A method for processing a digital file of the images, video and/or audio type which comprises a phase for putting into line per color layer and/or per audio channel, digital data of any audio, image and video file, a compression phase using algorithm in which each compressed value VCn of position N is obtained by subtracting from the value Vn of same position N of the original file, a predetermined number of successive compressed values (VCn-1, VCn-2, . . . ) calculated previously, and a restoration phase using an algorithm in which each restored value VDn of position N is obtained by adding to the value VCn, of the same position of the compressed file, a predetermined number of successive compressed values (VCn-1, VCn-2, . . . ).
Claims7
A method for processing a digital file notably of the image, video and/or audio type, comprising
- a phase for putting into line per color layer and/or per audio channel, digital data of any audio, image and video file, a compression phase in which the values of said file are successively compressed by means of an algorithm in which each compressed value (VCN) of row N is obtained by subtracting from the value VN of same row N of the original file, a predetermined number of successive compressed values (VCN-1, VCN-2, . . . ) calculated previously, and
- a restoration phase in which each of the values of the compressed file is brought back to a value close to the corresponding value of the original file by means of an algorithm in which each restored value (VDN) of row N is obtained by adding to the value VCN, of same row of the compressed file, a predetermined number of successive restored values (VCN-1, VCN-2, . . . ).
