Method for processing a digital object and related system

System for processing a digital object, the system comprising:

• a unit for denoising an original object of a first type containing noise in order to obtain a denoised object of said first type;
• a unit for obtaining a quasi-white noise object of the first type from a difference between the original object and the denoised object;
• a unit for applying to the denoised object a first processing comprising a neighbouring processing transforming the values of an object element according to the values of adjoining object elements in order to obtain a transformed object of a second type, the first processing being such that it would have the effect of structuring the noise contained in the original object if it were applied to said original object;
• a unit for applying to the noise object a second white processing in order to obtain a quasi-white transformed noise object of the second type;
• and
• a unit for introducing the transformed noise object into the transformed object.

A non-transitory computer-readable storage medium with an executable program stored thereon, wherein the program instructs a processor to perform operations comprising:

• denoising an original object of a first type containing noise in order to obtain a denoised object of said first type;
• obtaining a quasi-white noise object of the first type from a difference between the original object and the denoised object;
• applying to the denoised object a first processing comprising a neighbouring processing transforming the values of an object element according to the values of adjoining object elements in order to obtain a transformed object of a second type, the first processing being such that it would have the effect of structuring the noise contained in the original object if it were applied to said original object;
• applying to the noise object a second white processing in order to obtain a quasi-white transformed noise object of the second type;
• and
• introducing the transformed noise object into the transformed object.
