Method, apparatus and program for image processing

A non-transitory computer-readable storage medium comprising instructions which, when executed by a computer, cause the computer to:

• obtain a set of image data, the set being associated with one or more parameters representative of one or more image capture characteristics for the set and comprising pixel intensity values representing image pixels having respective pixel locations in an image;
• and
• for a given pixel intensity value in the set:
• determine an estimated noise value based on at least:
• the one or more parameters associated with the set, and
• a representative intensity value derived from one or more pixel intensity values in the set;
• and
• associate the estimated noise value with the given pixel intensity value.

An image processing system comprising a data processor and data storage, the data storage comprising instructions which, when executed by the data processor, cause the data processor to:

• obtain a set of image data, the set being associated with one or more parameters representative of one or more image capture characteristics for the set and comprising pixel intensity values representing image pixels having respective pixel locations in an image;
• and
• for a given pixel intensity value in the set:
• determine an estimated noise value based on at least:
• the one or more parameters associated with the set, and
• a representative intensity value derived from one or more pixel intensity values in the set;
• and
• associate the estimated noise value with the given pixel intensity value.
