ABSTRACT:
The method according the invention allows the extracting raw data from an image resulting from a camera shot.It comprises determining, for each point of the image of a combination V0[C,L] of color components of the image, calculating, for each point of the image, of a value VN+1[C,L], iterating said calculating a predetermined number of times then taking into account the values of the final image VNfinal[C, L] in each point of the image, calculating for each point of the image of the difference D [C, L]=VNfinal[C, L]−V0[C, L], calculating of a noise contextual datum VS, correcting the extracted raw data D[C, L], with the contextual datum VS, calculating of a corrected value I*[C, L] taking into D*[C, L] and presenting the extracted data under a desired angle.
